Need to find a better solution for your customer service woes? Line hunting can help you offer faster and more reliable customer support. Here is everything you need to know about line hunting and hunt groups.

What is Line Hunting?

Line hunting — also known as call hunting, hunt groups, and call routing — is a business phone system strategy that connects calls to multiple phone lines either simultaneously or one after the other. The idea behind line hunting is to ensure that no call goes unanswered and callers don’t have to endure long waiting times.

How Does a Hunt Group Work?

Hunt groups work by letting calls run through a sequence of phones or let them ring on multiple devices at the same time to ensure an operator answers. For instance, an incoming call may ring on multiple phone lines and devices, also called simultaneous ringing or ring groups. Or, you can have calls go through a sequence of agents until someone answers the call, also known as sequential ringing. In both cases, if no one answers, the call is sent to voicemail as a last resort.

The best part of using line hunting or hunt groups is that the caller has no idea that the call is traveling to different lines or agents. In other words, they are not aware that the first two rings may go to one agent and the next two to the next agent in line.

As a business, you have complete control over how you want your calls to move through the system. Additionally, depending on your provider, you may even be able to control how many rings each line gets before it moves to the next agent.

Combining Ring Groups and Hunt Groups

Businesses can use both ring groups and hunt groups to their advantage. Line hunting ensures that the call travels through a sequence to get to the next available agent while ring groups ring on multiple devices so that the first available employee can answer.

Fortunately, with VoIP numbers, businesses do not have to choose between one or the other call routing option. With both solutions available, your office will be prepared to answer calls quickly, reducing wait times and missed calls.

The Role Hosted VoIP Plays

A VoIP phone system can help your business improve customer service and caller experience by using advanced communication tools like call routing and international forwarding options. Furthermore, employees and agents who are part of these groups do not have to present in the same office or location to use the service. This is because VoIP works over the internet, enabling users to connect no matter their location or device.

Types of Line Hunting

There are a few different types of line hunting that you can implement in your office. Let’s look at these in more detail.

1. Multiline hunting
With multiline hunting, multiple phone lines work as a single group. When a call comes in, if a line is busy, the call moves to the next available one. The caller hears a busy signal only if none of the lines on the group are available.

2. Linear hunting
Agents are listed in a line or sequence. The incoming call travels through this line and if the first line is busy, the call moves to the next available line. This continues down the sequence until someone answers.

3. Circular hunting
In circular hunting, also known as round-robin routing, calls go down the sequence and start at the beginning of the line, if no one answers them. In this type of hunting, calls move down the sequence and start from the beginning again, even if an agent in between becomes available.

4. Most-idle hunting
In this type of hunting, calls are sent to the line that has been idle the longest. This is a good way to maintain balance and distribute the workflow across representatives.

What Is a VoIP Integration?

Voice over IP enables users to make and receive business calls from any location and through any device. This means your team can make calls from their computer or laptop while in the office or working remotely. All that is required is a stable internet connection. VoIP stores and transmits data securely in the cloud making it easy, safe, and convenient to use.

But the best part about VoIP is that it integrates comfortably with cloud-based applications and software. This is a great advantage over plain old telephone service. VoIP integrations let users switch between tools to store, share, and sync data between them. Doing so can cut down on time spent doing mundane, manual processes while keeping all your important data easily available.

16 Benefits of VoIP Integrations for Business

Any company that works with a VoIP integration or UCaaS will tell you that there are countless benefits of integration with their business phone system. Some top benefits of VoIP integrations include:

  1. Allowing users added versatility to multitask efficiently.
  2. Enabling call center agents to collaborate and share data and files.
  3. Seamlessly connect computers and telephones.
  4. Streamlining communications by unifying essential tools.
  5. Allowing users to stay connected from any device and any location.
  6. The ability to scale as needed.
  7. Having one centralized, unified platform for all essential business tools.
  8. Supporting remote working for distributed teams.
  9. The ability to receive live visibility and updates of call center activity.
  10. The ability to support a call center-type business.
  11. Easy set-up and management.
  12. The ability to innovate, customize, and adjust as your business needs evolve.
  13. Reducing monthly communication-related bills.
  14. Gaining access to local, national, and international numbers to boost global expansion and reach.
  15. Increasing office productivity and efficiency by streamlining workflows.
  16. The possibility of adding as many VoIP integrations as desired.

Key Features of VoIP Integrations

Now, what you can do with these integrations depends on your VoIP provider and what they offer. Some will offer a comprehensive set of calling features and analytics while others only offer a few select essential functionality. Here are some of the most common VoIP features to expect with your integrations:

1. Voice Calling

VoIP integrations let users make and receive calls through the internet. And when paired with a local, toll-free, or international number, your team can comfortably make local and international calls at relatively low rates. Plus, you benefit from VoIP features such as outbound calling, international call forwarding, and more.

2. Cloud Storage

VoIP providers offer cloud storage to help you securely store data for long periods. However, storage capacity and duration vary. Yet, this can help your phone system store and back up files, data, or call recordings on the cloud where they remain easily accessible.

3. Click-to-Call

Click-to-call generally works with most web browsers or software. This tool lets your team quickly call any number they find online or through their application. When they click the number, the call is placed through their VoIP device or softphone.

4. Contact Lists

This feature synchronizes your contacts across different platforms. This keeps customer information up-to-date and relevant, no matter where your teams access them. If contacts are not up-to-date or easily accessible, you can expect errors. So, such a feature leads to faster and more accurate customer service.

5. Voicemail, SMS, Fax

A voicemail transcription or voicemail-to-email feature sends voicemail messages and transcripts to users’ emails. You can then access these messages from anywhere. You can do the same with SMS and faxes. This way, you have documentation of voicemails, messages, and faxes securely stored.

6. Screen Pops

When calls come in, a ‘pop-up’ that displays customer information will turn up on the relevant agent’s screen. This provides the necessary context for the call, prepping the agent to respond optimally.

7. Call Recording

This feature lets you record incoming and outgoing calls and store recordings for future reference. You can use these recordings for training, documentation, analyzing trends, and more.

8. Data Sync & Call Reports

One of the most common features of VoIP integrations is the ability to automatically sync call and caller data. And most providers will offer that along with detailed call reports and analytics to help you understand your business’ call traffic.

8 Types of VoIP Integrations

There are a variety of VoIP integrations that can work well with your business phone system. However, which VoIP integration will boost your office’s productivity depends on what you are trying to achieve. Here are 8 types of integrations to consider:

1. Customer Relationship Management (CRM)

CRMs are mostly used to track customer contacts and their history with the company, track calls, SMS, faxes, emails, and so on. However, most CRMs available still depend on users manually and individually entering information.

A VoIP CRM integration can improve and streamline this process by automatically syncing communication-related details within your desired CRM.

This would increase efficiency by reducing the time spent entering this information accurately.

2. Helpdesk Software

Helpdesk software or customer support software serves as a central hub for managing and addressing customer inquiries and issues. It typically has features like ticket management, query escalation, multi-channel support, collaboration tools, etc.

Helpdesk integrations combine VoIP and customer support software to better equip your teams to provide quality and responsive customer support.

It helps you keep track of all customer interactions and communications in one place. At the same time, it offers users multiple channels and options to provide timely support.

3. Contact Center Software

This type of VoIP integration is designed to add call center and contact center capabilities to your business applications. With features like advanced call routing and call reporting, your teams can better handle incoming calls and increase efficiency.

For example, advanced routing and ACD can help route callers to the right destination within your organization. Similarly, the click-to-call feature will make it easy for your teams to place quick outbound calls.

These integrations bring call center functionality to your existing phone system.

4. PBX Integrations

You can also integrate VoIP into your existing PBX system. This gives you the ability to upgrade your legacy phone system by adding modern VoIP functionality to it. With VoIP and PBX working together, you can benefit from more global coverage, reliable call quality, secure voice network, and more.

5. Web and Video Conferencing

VoIP can also be integrated into web-based conferencing platforms. Think: Google Meet, Zoom, or even your in-house developed conferencing app.

This integration enables participants to join audio or video conferences through VoIP technology. It simplifies the process of hosting and attending virtual meetings and webinars. And it replaces the need for physical, traditional phone lines with more flexible communication technology.

6. Voice APIs

VoIP APIs are another common integration most providers offer. Application Programming Interfaces (APIs) allow developers to integrate and build systems that cater to specific business needs.

Your IT team can use voice or telephony APIs to integrate VoIP functionality into their custom applications or websites. This provides flexibility to create custom solutions tailored to your communication needs. And you can add key features such as click-to-call features, voicemail transcription, or call recording.

7. Mobile App Integration

More recently, you’ll find VoIP integrated into mobile apps. This allows users to make voice or video calls over the internet directly from the app. WhatsApp is a great example. These apps often use a data connection to transmit calls.

VoIP mobile integrations provide mobility and flexibility, enabling users to communicate using their smartphones and tablets from anywhere. Plus, you can quickly convert any app into one with communication-related capabilities.

8. Unified Communications (UC) Integration

UC VoIP integrations focus on adding multiple communication channels into one platform. Common channels include instant messaging, video conferencing, voicemail, fax, and email.

Some of these will have transcription abilities or send-to-email options. This way, users can switch seamlessly between these channels to communicate and collaborate. And they can quickly connect from any location or device. Your teams can increase productivity by centralizing communication tools, making it easier for teams to collaborate and share information.

As “business in the cloud” grows more and more common across industries, users are looking at integrations to increase efficiency and reduce costs. This is where unified communications as a service (UCaaS) and contact center as a service (CCaaS) come in.

Contact Center Versus Unified Communications: What’s the Difference?

CCaaS and UCaaS are business communication technologies. And while there are key differences between the two types of technologies, they work best when combined.

The main difference between UCaaS and CCaaS is that UCaaS focuses on internal communication and collaboration while CCaaS focuses on customer interaction. However, by bundling the two technologies into one cloud platform, you can save on communication costs. This means a monthly predictable bill and no need for extra hardware.

What is UCaaS?

UCaaS or unified communications as a service consolidates a business’ communication tools and applications into one unified cloud-based platform. Communication tools include voice, video, instant messaging, and conferencing. Additionally, they come with features such as call forwarding and routing, interactive voice response, voicemail-to-email and fax-to-email, and more.

A business’s IT team purchases these solutions to improve internal communication. These solutions can help businesses improve their office phone systems and streamline workflow by encouraging collaboration, flexibility, and mobility. UCaaS is similar to platform as a service, PaaS; where UCaaS makes unified communications available to businesses of all sizes.

What is CCaaS?

Contact center as a service or CCaaS also enables multichannel communication through one cloud-based platform. In other words, it is a call center software hosted in the cloud. Your CCaaS provider will create and maintain the software that allows you to enhance customer experiences.

With CCaaS, instead of the IT team, purchasing decisions are led by sales managers and leaders. This is because CCaaS solutions are geared towards sales and customer support. These solutions focus on creating easy methods for agents and employees to connect with clients and leads. Some common features include skill-based routing, customer authentication, outbound calling, etc.

How to Integrate Unified Communications Into Your Contact Center

To integrate unified communications into your contact center, follow the below steps:

1. Find the right provider for a voice and data network:

To get the combined benefits of UCaaS and CCaaS, you need a reliable voice network and/or phone system provider. This is usually a business phone service provider that provides your business with its international toll free service, VoIP numbers, and so on.

2. Choose the best features for your needs:

Browse through different features and services offered by your provider. You may even consider a virtual call center software that gives you access to standard and premium features such as call reports, direct inward dialing, call recording, IVR, and more.

3. Provide excellent customer service:

Use these features to create better customer experiences. Some ways you can do so include:

    • Offering multichannel support (voice, video, email, live chat, text message)
    • Using automation to create a faster and more productive workflow
    • Utilizing features to create a robust business phone system for internal and external communication

5 Benefits of UCaaS and Contact Center Collaboration

So, why does your business need a UCaaS and CCaaS collaboration? Here are the top 5 benefits of combining or integrating unified communications into your contact center.

1. More internal collaboration

With these technologies combined, different teams or departments within your office can work smoothly with each other. For instance, your marketing and sales teams must work together to determine the right leads and the right way to approach those leads. Being able to communicate easily and share information in a fast and secure manner can boost such collaboration.

2. Enhanced customer experience

With advanced communication features, you can strive to offer better customer service and caller experience. You can quickly forward callers to the right department or agent via your IVR system or through skills-based routing. You can also offer multichannel support for users who do not prefer phone conversations. Furthermore, a well-designed IVR system may even be able to reduce call wait times by providing troubleshooting help via prerecorded messages or sending callers to voicemail. Either way, the goal is to make the experience better for callers so that you retain these customers.

3. Lower communication costs

When bundled, you do not need additional expensive equipment or hardware to support both technologies. You can use your existing devices and phone system. Additionally, having both systems on the same platform ensures you have only one predictable bill per month instead of multiple bills. All of this helps reduce your monthly business communication costs which can result in significant savings for local as well as international businesses.

4. Enable remote working

Since both UCaaS and CCaaS work on cloud technology, you and your teams can work from any location and any device. This gives way to remote contact centers, virtual call centers, as well as distributed teams to work effectively even when working remotely.

5. Low IT maintenance

Finally, since these systems work over the cloud and are usually hosted by your provider, your business won’t have to worry about the costs of managing a data center. You merely rely on your provider, saving more in communication-related costs.

How to Measure and Improve VoIP Call Quality

Posted on by Luke Genoyer

A well-functioning business VoIP system ensures that your business stays connected with customers and clients, no matter where you are located. But an important part of using VoIP numbers or a VoIP phone system is to make sure your call quality is efficient and not compromised. In this post, we will look at how to measure and improve VoIP call quality.

What Are the Most Common Issues With VoIP Call Quality?

Before we delve into how to measure and improve  VoIP call quality, it is imperative to first understand what are the causes of poor VoIP quality. There are a few different factors affecting the quality of your voice over IP system. Fortunately, these VoIP issues are easy to fix.

So, what are the major causes of poor VoIP quality?

1. Latency

Latency refers to lag or delay that occurs between a speaker and receiver. In other words, there is a delay between the time the speaker says something and the receiver hears it. This results in echoes or speakers speaking over each other. While latency doesn’t affect the VoIP call quality, it does make it difficult to communicate effectively, leading to frustration and confusion.

2. Jitter

Jitter occurs when a data packet is delivered later than the rest of the packet. VoIP and SIP calls occur through the transmission of data packets from one user to the next. A data packet can take various paths through the interweb to reach its destination. Furthermore, all the packets may not take the same path which can lead to one or two packets arriving later than the rest. High levels of VoIP jitter can result in bad call quality and missing or jumbled audio.

3. Packet loss

Packet loss refers to the loss of data packets during transmission. There are a few different types of packet loss:

  • Completely lost and never reaches the destination
  • Arrived late, therefore discarded
  • Contain errors, therefore discarded
  • High packet loss leads to bad call quality as pieces or chunks of audio are missed or are hard to decipher.

4. Poor internet connection

Since VoIP calls occur over the internet, having a strong internet connection is essential to the proper functioning of your business phone system. If your ISP is optimized merely for surfing the internet and uploading or downloading files, then you won’t have even bandwidth for speedy VoIP connections and transmission of data packets. You can use online speed testing tools to get a good understanding of your internet capabilities such as:’

  • Upload speeds
  • Download speeds
  • Jitter times, etc.

How is VoIP Quality Measured?

The Mean Opinion Score (MOS) is the leading tool to measure VoIP call quality. MOS measures subjective call quality and its scores range from 1 (bad VoIP quality) to 5 (excellent VoIP quality).

Some standards and metrics to consider when measuring VoIP include:

  • The ITU standards P.861 (PSQM) and P.862 that state how MOS scores should be calculated.
  • The ITU standard P.563 that calculates call quality passively and includes an R factor to estimate a MOS score.
  • PESQ and PAMS methods that need a license from Psytechnics.
  • Cisco IOS that has built-in tools to measure metrics and estimate MOS during test calls.

How Do I Test VoIP Quality?

In order to test VoIP call quality, you will have to monitor network latency, jitter, and packet loss. VoIP quality tests will enable close monitoring of calls. Call details, activity reports, and alerts can help you identify areas that need improvement or solutions.

What is a Good MOS Score?

MOS measures VoIP quality by assessing the user’s opinion of the call’s quality to score it. On a scale of 1 (bad) to 5 (excellent), a good score for VoIP calls falls between 3.5-4.2 range. This is what a MOS chart looks like:

MOS Quality Issue
5 Excellent Perfect quality
4 Good Less perfect; may include some loss of quality
3 Fair Slightly strained quality
2 Poor Strained quality
1 Bad Heavily strained quality

7 Ways to Improve VoIP Call Quality

So, how can you improve VoIP quality, and what are some helpful troubleshooting methods? Here is a list of 7 ways to fix your VoIP call quality:

1. Check your internet speed

The first step to ensuring high VoIP call quality is choosing the right internet service provider. Make sure you have enough bandwidth for VoIP calls and regularly test your internet speed using online testing tools.

2. Check network & equipment configuration

One of the top troubleshooting methods is to check if your network and equipment are properly configured. A network that is not properly configured can negatively affect call quality. This is especially true if you are transmitting voice and data.

3. De-jitter your VoIP

Jitter is often a result of network congestion, packet lags, configuration issues, etc. The best way to combat jitter is to invest in a de-jitter buffer such as a router or Edge device that receives a Real-Time Protocol (RTP).

4. Check your cabling

Most of the current cabling for phone communication and data transmission is a CAT 5 or higher. Ensure your phone system has the right wiring and cabling for its purpose.

5. Choose good handsets

Another quick and easy troubleshooting method is to get new and improved headsets. Low-quality headsets can easily hinder call quality and make simple communication difficult and unclear. Get good headsets for your employees so they have the best tools to work with.

6. Avoid hubs on your local access network (LAN)

A LAN with multiple hubs can result in low call quality. The recommendation is that each phone is individually connecting to the switch.

7. Determine whether “crackling” is because of faulty wiring or hardware problems

Lastly, if you are experiencing “crackling,” it is important to identify where it is coming from so you can fix it appropriately. Are all lines experiencing crackling? Are cords not properly or tightly plugged in? And so on.

Voice over IP security is something you must pay close attention to. In this detailed guide, we will cover everything that you need to know about voice over IP security and encryption.

Are VoIP Calls Secure?

While voice over IP is fairly secure, there is still a possibility that hackers may target and compromise your VoIP system. To avoid such security breaches, VoIP security should be taken seriously and steps must be taken to ensure a secure VoIP phone system.

The 6 Most Common Vulnerabilities of Your Voice Over IP System

In order to best secure your VoIP numbers against hackers, you must be aware of the different VoIP security vulnerabilities and types of attacks possible. Here are the top Voice over IP security vulnerabilities to be aware of:

1. Default security settings
VoIP credentials need to be configured accurately. Your web phone is essentially a smartphone that has computer-like capabilities. Instead of using default settings and passwords, users should configure secure credentials to avoid vulnerabilities.

2. Using VoIP over WiFi
Using shared WiFi or networks can often cause security breaches. And since VoIP systems need an internet source — mostly WiFi — to work effectively, there is a chance of the security being compromised when using a public or shared WiFi connection instead of a secure office connection.

3. Attacks on the network
Similar to the WiFi being hacked, one’s user network can also be disrupted and breached. There are various types of network attacks. Attacks on one’s business phone network can directly impact their VoIP security.

4. Remote eavesdropping
In most cases, when your system is vulnerable or attacked, hackers have the ability to eavesdrop on confidential and private information. This information can then be used against your company, either via blackmail or by selling it to the competition.

5. Viruses infecting the system
The internet can be easily invaded by viruses and malware. Any internet application and device associated with it is therefore prone to viruses and security breaches. And since VoIP uses the internet, it too remains vulnerable to such attacks.

6. VoIP phishing
Phishing, also referred to as vishing, is a concept similar to catfishing. With VoIP phishing, when a call is made, the caller pretends to be from a credible organization and inquires about private or sensitive information. These callers often perform VoIP phishing by gaining information about you and your company which makes them appear as legitimate and credible. This creates a false sense of security which may result in sensitive information being shared.

How to Recognize a VoIP Attack

So, how do you know if your VoIP phone system has been attacked? Here are a few key indicators of a VoIP security breach:

1. Huge monthly bills
Has your monthly VoIP bill increased dramatically and unexpectedly? If so, there’s a good chance that your VoIP system has been attacked. Hackers are able to make a call’s IP similar to one recognized by your system. This allows them to use your VoIP infrastructure to make multiple calls without being charged.

2. Suspicious call history
Similar to the above issue, if your call history is irregular and doesn’t fit the number of calls your business is making, it is likely that a hacker is using your system to make calls. To combat this, keep tabs on your call history, check it regularly, and make note of unrecognized call patterns and disparities.

3. Redirected internet searches
If a search through your VoIP system has been redirected to an unknown or unwanted page or website, then it is a sign of your internet system being hacked. Always remember to log out of the system when users are done.

Is Voice Over IP More Secure Than PSTN?

VoIP can be more secure than PSTN depending on the measures your business and your VoIP provider take to protect it. This leads us to the next section that details various methods to increase VoIP security for your business phone system.

Are VoIP Calls Secure?

How to Protect Your VoIP System

There are various policies that businesses can implement to have a secure VoIP system. Encrypting voice traffic and running regular security checks are the best ways to protect your VoIP calls. Let’s look at the top best practices for voice over IP security:

12 Best Practices to Secure Your VoIP System

1. Encrypt voice traffic
Voice encryption is of utmost importance. Encrypt voice traffic and other traffic that moves through your VoIP system using encryption techniques.

2. Encrypt WiFi
Besides encrypting your voice traffic, you should also encrypt your WiFi providing it with maximum security from breaches.

3. Use a VPN
A virtual private network or VPN adds an additional layer of security. A VPN protects calls occurring over mobile or wireless networks and is a good solution to keep your system secure for on-site as well as off-site workers.

4. Strong passwords
This goes without saying. Make an effort to understand your security system, change default security settings, use strong passwords, and change passwords regularly.

5. Run regular security checks
Conduct regular security checks to test your system and see how it responds and how your security measures perform. Look for backdoors, vulnerabilities, or traces of past hacks.

6. Enable Network Address Translation (NAT)
Network address translation (NAT) is a router feature. This feature gives your VoIP system and devices associated with it a private IP address that is only visible on your LAN. It, therefore, acts as a wall between your system and the internet, making it difficult for outsiders to view your IP address. If they can’t view the IP address, then they can’t use it to hack your system.

7. Close Port 80 With a Firewall
VoIP devices — especially phones — on a local access network need ports to connect to the internet. A port is an active channel located on a router. Port 80 or the Hypertext Transfer Protocol is a port on the router that has HTTP traffic. HTTP traffic is the kind that is used on most websites. This is why port 80 is prone to easy hacking. Use a firewall to close your port 80 so that hackers can’t use it to access the web interface.

8. Keep systems and software up-to-date
Whether it is the computers’ operating systems or anti-virus software, keeping these systems and software up-to-date is crucial to security and protection. You may even consider using an intrusion prevention system or VoIP firewall to add additional layers of security.

9. Avoid international calling, unless needed
Unless your company works in international business and calling internationally is crucial to its operations, it is a good practice to disable international calling. However, if your business needs to call internationally, then make sure to check call records and history often to ensure there are no irregularities.

10. Consider remote device management
Remote device management enables remote access to a device which can then be wiped if the employee quits or is fired, or if the device is stolen. Whether your business issues laptops or implements a remote device management policy, ensure you activate remote device management on devices used by employees.

11. Educate users about VoIP security
It is important that all users of your VoIP phone system understand how the system works and how to keep it secure. Take time out to educate your employees about VoIP security and best practices.

12. See something, say something
By educating employees about VoIP security, you can train them to observe and notice irregularities or suspicious activity which they can then report to you. Such suspicious activity should then be brought to the notice of your VoIP provider.

Most Common VoIP Encryption Methods

In order to encrypt your VoIP traffic, you need to first understand how VoIP and SIP work together. SIP technology or Session Initiation Protocol in a VoIP phone system begins and ends a call session. SIP vulnerability occurs when a hacker invades the SIP process and uses it to eavesdrop on the call, collect sensitive information, and more. To secure your VoIP system, you must first secure your SIP transmission. Here are some VoIP encryption methods to consider:

  • Transport Layer Security (TLS)

Typically, this type of security is used to encrypt a VoIP SIP system when sessions begin and end. TLS keeps your VoIP secure by authenticating a security certificate and encrypting the information transmitted between two or more parties.

  • Secure Real-Time Transport Protocol (SRTP)

Typically, this type of security is used for high bandwidth VoIP usage. For example, you can use SRTP to secure voice calls and avoid bad or low call quality. SRTP protects voice data and information during the call by encrypting the call and adding message authentication within the channel.

  • Physical Protection

Lastly, you want to protect your company’s data from unhappy employees and other users who may have physical access to your VoIP system and hardware. The best way to avoid privacy and security breaches, such as the ones mentioned above, is to limit access to your system and enable remote device management.

Here we will look at how these phone systems differ so you can make a better decision for your company.

Understanding the Difference Between VoIP and PSTN

Technology has advanced greatly over the past two decades, enabling exceptional options for businesses in regards to their communication systems. When researching business phone systems for your communication needs, you will come across voice over IP (VoIP) and public switched telephone network (PSTN) as two major options. But how do you decide which is better for your communication needs? Here we will look at the difference between VoIP and plain old telephone service.

How Does VoIP Work?

Voice over IP or VoIP, transmits voice messages via the internet. With VoIP, voice gets converted into digital signals and then get transferred from one end-point to the next using secure network protocols. Upon reaching the recipient, the signals get converted back to voice messages.

Since VoIP is not attached to a physical line, users with a VoIP phone system can make and receive calls from any location and any device. All they need is a stable internet connection. Additionally, VoIP numbers or virtual phone numbers also route calls over the internet, letting companies do business with target countries without increasing expenses. You also get access to a suite of cloud communication features.

VoIP system costs are considerably less, as well. Users can easily scale up or down, as needed, without buying new lines or paying for additional equipment. In fact, there are no set-up or installation fees. And you won’t even need new equipment. VoIP proves to be more cost-effective, especially considering the features available and international calling.

Is IP Better than PSTN?

PSTN connects callers through a circuit-switched telephone network. This type of phone system has been used for years. When used, calls are transmitted through a network from one end-point to the next. The call quality is generally excellent.

Businesses using PSTN will need a different physical phone for each employee. The costs for desk phones can skyrocket to $300 per phone! Plus, you must then deal with installation and clunky hardware.

On the other hand, the cost for one SIP trunk ranges from $20-$30. This can be used by many employees. Plus, there’s no any set-up/installation and maintenance costs.

Small businesses with 10 or fewer employees can benefit from a VoIP phone system. However, even when the business size grows, they would be better served with a cloud PBX.
