Gone are the days of using an outdated and expensive phone service to make international calls. There’s a better way to call your customer overseas. VoIP offers a more reliable and feature-rich solution with cost-savings along the way.

Is VoIP Good for Calling Internationally?

Yes, voice over IP (VoIP) works great for international calling.

The technology has been around for years. But in the past, you needed a level of technical knowledge to use VoIP. But nowadays, making international calls with VoIP is easier than ever.

Throughout its early history, VoIP was also primarily used by residential users and people in developing countries that wanted to call overseas. But in the last few decades, more and more businesses have started using VoIP for business calling.

With a fast and easy setup, you can use this solution across multiple devices. As long as you have a stable internet connection and sufficient bandwidth, you can make high-quality international calls through VoIP.

Benefits of Calling Internationally with VoIP

So, why should you use VoIP for international business calling?

• High-quality calls
When making business calls, call quality is of the utmost importance. The best VoIP providers will ensure excellent call quality when making international calls.

• Two-way calling and local caller ID
Our VoIP solution enables you to call internationally with a local number. This means that your team can make calls to anywhere in the world and show a local number that corresponds to the country they’re calling. This will improve connection rates and leave a callback number if the call is missed.

• Portability
Whether your agents work from a central office, overseas, or remotely, they’ll be able to make international calls with your VoIP service. And to add to that, agents can make calls on the go using multiple devices.

• Reliability
Provided you have the right setup in place, VoIP is very reliable. Many providers guarantee upwards of 99.9% availability, and some providers even boast zero downtime.

If something goes wrong, issues with VoIP are easier to troubleshoot than with an on-premises system.

• Affordability and cost-savings
Affordability is one of the major benefits of using VoIP to call internationally. Because calls are delivered over an internet connection, calls are cheaper than traditional PSTN calls. This cost-savings is passed from provider to customer.

• Scalability
VoIP allows you to add and remove lines and users as needed. Don’t worry if the global ambitions of your business slow down. You can just pause the VoIP service and pick it back up when ready.

In addition to the benefits above, installation and maintenance costs are traditionally lower when using VoIP compared to traditional on-premises phone systems.

How Do I Use VoIP to Make International Calls?

To make international calls using VoIP, you must enter a plus sign or dial-out prefix, the country code, and the phone number you want to call.

For example, if you want to call a phone number in the United States from overseas, you would enter + 1 and then the subscriber number you want to reach. Make sure to include the subscriber’s area code.

It’s that simple. You can do it using an IP phone, computer, or app on your mobile phone. In today’s day and age, the user experience is quite seamless.

Are International Calls Free With VoIP?

International VoIP calls are not free — the charge depends on the countries involved. However, using VoIP for international calling is typically far cheaper than using a traditional phone service.

As you probably know, traditional phone service providers can charge an arm and leg for international calling. So, if you want to make cheap international calls, VoIP is the best way to do that.

In fact, VoIP providers can be up to 90% more cost-effective than traditional phone service providers for international calling. For many countries, international VoIP calls can cost as little as 2 cents per minute.

But it depends on your provider, the package you choose, and the countries you call.

What is the Best VoIP Provider for International Calls?

If you’re looking for a VoIP provider to use for your international calling needs, there are a few factors to evaluate. While you’ll find many different providers in the market, not all of them provide the same services. So, you’ll need to consider the specific needs of your business and make an informed decision.

Similarly, when it comes to international calling, not all VoIP providers use the same termination and routes to deliver calls. Some providers will try to cut costs and use low-quality routes.

Here at United World Telecom, we use only the highest quality routes to deliver international calls. In addition, we have a state-of-the-art global telecom network with multiple layers of redundancy.

With the growing popularity of VoIP phone services, more and more businesses are using VoIP to communicate reliably and cost-effectively. This includes businesses trying to expand their global reach and grow in target markets.

Voice over IP or cloud telephony makes it easy to communicate across geographical areas via the internet. However, restrictions and unreliability can interrupt this comfort if your VoIP phone system is not properly optimized or compliant.

In this article, we’ll discuss optimizing VoIP for India — from understanding regulations to implementing best practices.

Using VoIP in India

While VoIP runs sufficiently well on its own, the best way to make the most out of your VoIP phone system is by optimizing it. To do this, you’ll need to:

• First, understand local VoIP regulations to maintain compliance,
• And second, build your VoIP infrastructure with the right tools and strategies.

Together, this will optimize your phone system so it connects and terminates calls effectively without any interruption. After all, without the ability to properly communicate with customers, how will your business grow?

Restrictions to Pay Attention to

While VoIP telephony is not illegal in India, there are a few restrictions. And if you plan on doing business within the country, then you need to understand how VoIP works there. These regulations are overseen by the Telecom Regulatory Authority of India (TRAI) and the Department of Telecommunications (DoT).

Here are the key restrictions in India to pay attention to:

• No call routing should happen against the interest of the local PSTN service provider with respect to toll bypass.
• IP to PSTN/landline calls are not allowed — cannot terminate VoIP calls to PSTN lines in India
• Cannot use VoIP gateways within India
• IP phones should work only within their VoIP infrastructure and should not connect to the public network or WAN.
• Calls that run through PSTN gateways should never connect directly to a VoIP phone or VoIP PSTN gateway in a different geographical location

*Note: Regulations and restrictions mentioned in this article are current at the time of publishing and are subject to change.

VoIP in India: What is Allowed?

The above restrictions may seem discouraging but remember that VoIP is legal in India to a certain extent. With that in mind, what is allowed?

• Calls between two VoIP phones (IP to IP) in the same region or different geographical locations
• Calls from VoIP to PSTN gateway in the same geographical area.

What Does This Mean for Businesses in India Using VoIP?

So, how do these restrictions impact businesses in India? Let’s look at different use cases:

1. You have a company in India and solely do business with prospects within the country.

In this case, VoIP is legal if the prospects you call also use VoIP or internet telephony. Don’t try calling from VoIP to PSTN or landlines.

2. You have a company in India but solely do business internationally.

In this case, you can make IP calls to any international location as long as the call originated from IP and terminated to IP.

3. You have a company outside of India and want to do business locally.

You will need an Indian local phone number to make calls to customers in the country. However, these calls must display the true caller ID, which is the ID of the caller’s location. In other words, masking your caller ID to display a local number is illegal.

Thankfully, VoIP providers that work closely with local Indian telecom operators can get you a solution that works within India’s caller ID regulations. In most cases, they establish local points of presence (PoPs) and route calls through local routes instead of international routes, respecting local PSTN setups.

Optimizing for VoIP in India: Factors Affecting VoIP Call Quality

Now that we’ve understood how VoIP works in India, let’s look at how to optimize your VoIP phone system.

Optimizing for VoIP in India means three things:

1. Make sure you meet all necessary VoIP network requirements
2. Troubleshoot common call quality issues and
3. Use the right VoIP phone service.

First, let’s look at the different VoIP network requirements and many factors impacting call quality:

1. Internet quality and bandwidth usage
2. VoIP codecs
3. Quality of Service (QoS) settings
4. VoIP phone service provider

1. Internet Quality and Bandwidth Usage

For any VoIP service to function efficiently, you need a stable and reliable internet connection and enough bandwidth. This is simply because VoIP calls travel over the internet.

So, first, check your internet speed using online testing tools. Remember that you will need to set aside quite a bit of bandwidth for only VoIP calls. Other activities such as browsing, email checking, web surfing, additional applications, etc., can reduce how much bandwidth is left for calls to travel efficiently. And if you have low bandwidth, you will have slower speeds and a lower-quality voice.

According to the FCC, VoIP calls require internet speeds that have less than 0.5Mbps (minimum download speed) download. Note that this is the minimum requirement.

To calculate the bandwidth needed for your VoIP system, you need to understand your business’ call flow and other internet activities. Consider these:

• How many phone lines do you need?
• How many calls will occur concurrently?
• Will other applications run simultaneously on the same network?
• What upload/download speed does your ISP provide?
• What voice codecs does your VoIP/ISP provider offer?

Next, use this chart to determine how much bandwidth is recommended for your approximate concurrent calls. For high call quality, the recommended range of bandwidth for each concurrent VoIP call is anywhere from 85-100Kbps.

Number of Concurrent Calls	Bandwidth Recommended
1	100 Kbps
5	500 Kbps
10	1 Mbps
15	1.5 Mbps
20	20 Mbps

You can also check with your VoIP provider to understand what they recommend for their particular service. Then, ensure your ISP is able to provide what your office needs to make VoIP efficient.

2. VoIP Codecs

Next, you want to make sure that you use the right codecs for voice and audio. VoIP codecs digitize voice signals into data packets (compression). Once transported, the codecs convert them back to voice (decompression).

This process of compressing and decompressing voice signals directly impacts call quality. And if not done properly, it can lead to latency, jitter, packet loss, and more. So, you and your VoIP provider need to work together to ensure codecs are adjusted properly to improve voice quality and reduce bandwidth usage.

Now, which codecs are best for VoIP? The general consensus is that G.711 offers the best call quality. Although, most providers also accept G.729 (low bandwidth alternative) or G.722 (not offered by most). Here’s a chart for reference:

Codec	Bitrate	Bandwidth Usage
G.711	64 Kbps	87.2 Kbps
G.722	48-64 Kbps	80 Kbps
G.729	8 Kbps	31.2 Kbps

3. Quality of Service (QoS) Settings

You can also use QoS to optimize your VoIP system and fix voice quality issues by prioritizing network traffic that passes through the router. Through this process, you give more bandwidth value to VoIP calls over other kinds of traffic.

This means your calls don’t compete with web browsing or streaming. And, by extension, you reduce network congestion so that inbound and outbound calls are not affected.

To change your QoS settings, you’ll need to work with your ISP and VoIP provider to get exact instructions for your particular setup. However, implementing QoS changes does not take very long and you can expect it to work in your favor soon.

4. VoIP Phone Service Provider

This one goes without saying: Optimizing for VoIP in India is incomplete without the right VoIP phone service provider.

The above-mentioned tips will help you build a good foundation for VoIP. However, without a reliable provider, your call quality can experience issues leading to dropped calls, calls that don’t connect, and so on.

Plus, if you have an unresponsive provider – or one who is hard to reach – you’ll end up having to troubleshoot quality issues on your own. This can prove tricky if you do not have an in-house IT or telephony engineering team.

Lastly, since VoIP in India is a slightly tricky affair, you want to make sure you work with a provider who knows what they are doing. You want a VoIP provider that has been working in the country for a long time and understands the different regulations and restrictions well.

This will require some research, but as you shop around, look out for telecom companies that have been doing this for a few decades. Ask them how they comply with these regulations and provide reliable connectivity. This will also help you determine the company’s responsiveness and credibility.

Traditional phone systems are holding your business back from increased growth, efficiency, savings, flexibility, and more. This is why companies — from small businesses in the US to tour packages in Europe — switch to VoIP, as it offers everything from scalability to affordability. So, if you’re looking to cost-effectively upgrade your business communication, voice over IP is the solution for you.

In this article, we’ll cover why and how to switch to VoIP, and dive deeper into reasons to migrate.

• When to Migrate to the Cloud
• VoIP vs PSTN
• 6 Reasons to Move to VoIP
• How to Switch to VoIP

When to Migrate to Cloud Communication?

High monthly bills, issues with call quality, and unacceptable downtime are all clear signs that it’s time to modernize your legacy system and switch to VoIP.

But, what are the less obvious indicators that an upgrade to your system is necessary? Here are some questions to consider:

• Do you manage global or remote teams?
• Can your current phone system support your failover, disaster recovery, or business continuity plans?
• Are you planning to expand to new markets or regions? Or, do you already have customers in different countries?
• Is it hard and time-consuming to make changes to your current system as needed? Specifically, with call routing and forwarding capabilities?
• Do you need features like IVR, caller ID management, or call recording to provide a more efficient and enhanced service to customers?

Even if you answered yes to only one of these questions, you would benefit from a VoIP phone system. And in most cases, your business benefits in more than one way.

From connecting your distributed teams to offering increased functionality, a voice over IP solution can help you accomplish business goals while also improving business processes – all under one platform.

Landlines vs VoIP: The Difference in How They Work

But what if you have a landline phone system set up? And how are landlines different from VoIP?

Let’s start by defining the difference between traditional landline systems and voice over IP networks. This will not only help you better understand elements of the migration process, but also the above mentioned reasons to switch.

When you make a call using a landline, it travels via the Public Switch Telephone Network (PSTN). And this long-standing telephone network uses physical phone lines and switching centers to connect your calls.

Since VoIP is a cloud-based service, it operates differently than traditional systems that rely on landline connections and the PSTN. In fact, voice over IP transmits calls to your desired destination using an internet connection and packet-switching technology.

In other words, the main difference between VoIP and PSTN systems is – the first uses digital pathways to transmit calls, whereas the second uses physical phone lines.

Let’s take a closer look at other key differences between VoIP and PSTN:

	VoIP	PSTN / Landline
Connectivity	Make calls via the internet, faster transmissions	Make calls via landlines / physical cables and switching centers
Quality	Higher call quality, with clearer sound; can fluctuate depending on your IP network	Average, consistent call quality
Flexibility & Mobility	Highly customizable; place calls from any location and device	Less customization; place calls from only one location
Features	Variety of advanced calling features	Limited features
Price	More affordable than PSTN (even with international calling)	Expensive (especially for international communication)

6 Reasons to Switch to VoIP

So, why should you make the switch to VoIP? Let’s take a look at 6 reasons to migrate:

1. Save BIG

Voice over IP is an affordable solution for both small businesses and enterprises, especially when compared to legacy systems. This is because it doesn’t rely on physical phone lines, meaning you stand to avoid high international and long-distance calling fees. And since you don’t need additional equipment or routine maintenance to use the service, VoIP also reduces your overhead costs.

2. Access to Advanced Communication Features

Unlike traditional phone networks, many VoIP services include access to additional features that are only available through the cloud. This not only increases the functionality of your system, but also helps you provide a more effective service.

3. Higher Call Quality

Since cloud telephony uses digital pathways instead of copper phone lines, calls travel faster while delivering a clearer, higher-quality sound.

4. Flexibility & Mobility

Typically, you can manage your communication stack through your VoIP provider’s online control panel. In other words, your phone system is accessible and manageable from any location or device.

5. Connect Global Teams

As you can access VoIP from anywhere in the world, it’s the perfect solution for businesses looking to connect international, distributed, offshore, or remote teams.

6. Increased Scalability

Voice over IP is a highly scalable solution. You can upgrade or downgrade your service as needed, all without changing your entire system.

How to Switch to VoIP? 7 Steps

Now, let’s go through the migration process and discuss how to switch to VoIP. Here are the 7 steps we will cover:

• Plan Your Switch
• Test Your Internet Network
• Prepare Your Infrastructure
• Sign up with a Reliable Provider
• Select VoIP Hardware
• Train Your Teams
• Install VoIP and Configure Features

1. Plan Your Switch

Transitioning to cloud communications is typically a straightforward process, especially if you have an effective plan in place. And a well-thought-out plan always begins with defining your communication needs.

Here’s a checklist to help you identify them:

• Establish an overall budget. How much are you willing to spend on equipment, features, add-ons, plans, and so on?
• Figure out your pain points with your current phone system. What do you wish you could add or change about it?
• Outline your business goals for the next 5 years. How can a new phone system help you achieve these benchmarks?
• Determine your desired services and features. Which ones are essential, and which ones are just nice to have?
• Decide on your deployment method. Do you plan on modernizing your existing infrastructure or replacing it completely?
• Consider your average number of calls, number of users/lines, call traffic behavior, and so on. Do you expect these data points to stay consistent or fluctuate over time?

2. Test Your Internet Network

One of the most important VoIP network requirements is a stable internet connection with adequate bandwidth for your specific call traffic. Without a reliable IP-network, you could run into voice service issues. For this reason, many providers recommend a high-speed broadband connection.

To ensure your network can handle simultaneous calls and to achieve the best call quality, it’s vital to test your internet. You can do so by running a speed test. You can find these online, and they are usually free to use. These tests analyze your IP network’s latency, download speed, and upload speed.

After reviewing these data points, you’ll know how many calls your network can actually handle. Note: You need 100 kbps per line for most voice services. If your current internet connection can’t handle your business’ average call traffic, reach out to your ISP and upgrade your bandwidth before switching to VoIP.

3. Prepare Your Infrastructure

Once you’ve figured out your bandwidth requirements, you must evaluate and prepare your current infrastructure.

Start by cataloging damaged equipment or outdated hardware that you wish to replace. This way, when it’s time to purchase new equipment, you know exactly what you need.

During this step, you should also consider the following:

• Wired connections vs Wi-Fi – Although VoIP works with wireless networks, it is often recommended that users use wired, Ethernet cables instead. This is because wired connections are more reliable and help prevent congested networks. We recommend using Cat 5e or Cat 6 Ethernet cables.

• Multiple routers vs switches – Using multiple, general-purpose routers to connect your devices to the internet can affect call quality, contribute to a congested network, and prompt other technical issues. That’s why many providers suggest using network switches instead, as they extend the functionality of your router. This means, you don’t need multiple routers on your network, so you experience less congestion, delay, and better call quality.

• VLAN – A VLAN configuration can help improve VoIP performance and avoid network traffic congestion, meaning a lower chance of voice quality issues. Consider setting one up, especially if you operate a medium-sized business or enterprise.

• SIP ALG – Considering disabling the SIP ALG feature on your router, as it may contribute to multiple VoIP problems such as one-way audio or dropped calls.

4. Sign Up with a Reliable Provider

Next, you’ll need to sign up with a reliable VoIP provider. This involves in-depth research and comparisons between brands to ensure you get the best cloud phone service for your needs and goals.

Review each provider’s:

• Pricing plans and models, including annual, monthly, pay-as-you-go, per-minute, per-user, and per-line billing
• Free trial or demo offerings
• Setup, activation, or other hidden fees
• Activation times
• Available services, features, and add-ons
• VoIP requirements
• Compatibility with existing equipment and third-party applications
• Country coverage
• Distributed data centers and Points of Presence (POPs)
• Service Level Agreements (SLA) and Terms of Use
• Network reliability and uptime guarantee
• Crisis management initiatives and disaster recovery plans
• VoIP security, encryption protocols, and service monitoring practices
• Contract requirements
• Customer and technical support services
• Telecom and industry experience
• Case studies and customer reviews

It will take some time to collect and compare this information. But, this is arguably the most important step when making the switch to VoIP. And that’s because your provider contributes to the quality, security, and reliability of your phone service.

Look for providers that will work with you to craft the best solution for your business and are quick to handle any issues that arise.

5. Select VoIP Equipment

The VoIP equipment you select will vary depending on your existing infrastructure and chosen deployment method.

If you plan on modernizing your legacy phones, you’ll need:

• VoIP gateways or adapters for each device
• Ethernet cables to connect the gateways to your router or switch

If you want to replace your traditional desk phones with VoIP-compatible ones, you’ll need:

• IP phones (There are many options on the market from IP conference phones to wireless IP devices; Pick the one that fits your budget and communication needs).
• Ethernet cables for internet connection

If you prefer to use other equipment like computers, you’ll need:

• Softphone feature
• IP-enabled devices such as smartphones, tablets, laptops, computers, etc.

Other optional equipment includes:

• VoIP headsets
• Microphones

The great thing about VoIP is that you don’t need a ton of equipment. All you need to get started is a stable internet connection, IP-enabled device, and a VoIP service with the softphone feature. So, the equipment and hardware you select really depend on your communication needs and preferences.

6. Train Your Teams

Whenever you introduce new hardware, software, methods, and so on into the workplace, provide employee training and give your teams time to adjust.

Walk your staff through features and provide them with resource materials. Make sure to start training before you fully switch to VoIP, so employees are ready to go when you migrate. You might consider creating a process flow diagram that outlines all the steps involved in using the new VoIP system. This diagram can serve as a visual guide for your employees, helping them understand how to navigate the system and troubleshoot common issues effectively.

In most cases, VoIP services are simple and intuitive. This means a smooth onboarding experience for you and your teams.

7. Install and Configure VoIP

Now, it’s time to set up your VoIP system. This is another step that varies depending on your provider, existing hardware, and deployment method.

First, plug in and connect all your equipment, if you haven’t already done so. Then, log in to your provider’s control panel to add users and set up your desired features. If your provider offers a suite of features, prioritize configuring the ones you identified as essential.

If you still aren’t sure which features to set up, here are some suggestions to get you started:

• Customized Greetings – establish a professional and welcoming brand voice.
• IVR & Call Flow Designer – help guide callers to their desired destination.
• Call Routing – send calls to an alternate destination based on date, time, location, etc.
• Failover Forwarding – maintain business continuity by sending unanswered calls to a backup location.
• Call Recording – record calls for training, liability assurance, or liability purposes.
• Voicemail Messages & Voicemail to Email – personalize voicemail prompt and conveniently forward messages to your email.

Once you’ve added users and configured your chosen communication features, your VoIP system is officially operational.

For specific fixes for these problems, check out our VoIP troubleshooting guide.

Steps to Optimize Your VoIP Network

Now, when it comes to improving and optimizing your VoIP network, you have multiple options. The key is to identify the problem and then find the best solution. In some cases, your VoIP provider can help. And in other cases, you’ll need to rectify the problem yourself.

So, really, you can start by contacting your provider or running tests on your own. Let’s go over how you can optimize your VoIP network and different factors to keep in mind:

Related: How to Achieve the Best VoIP Call Quality for Your Business?

1. Adhere to VoIP Network Requirements

To properly set up a VoIP phone system, you must pay attention to network requirements that enable VoIP to function effectively. This includes:

• Using the right equipment
• Having adequate network bandwidth
• Using wired connections over wireless networks (WiFi)
• Setting up QoS for data prioritization
• Network monitoring and testing
• Securing and encrypting the network.

A good way to optimize your VoIP network is to ensure you’ve done the above-mentioned best practices. These will create a healthy environment for your VoIP phone system.

We’ll talk about some of these in more detail below. Additionally, we put together a comprehensive guide to VoIP network requirements to help you get started.

2. Contact Your VoIP Provider

For a quick resolution — especially if you don’t have in-house network or voice engineers — it may help to first contact your provider. Since they know the network requirements needed to run VoIP properly, they can let you know how your current setup is failing.

They can also provide additional testing and monitoring services to identify the problem and offer solutions accordingly. They should already be monitoring your service, so it is easier for them to determine what is causing the issue.

If you want to exhaust all your self-service options before calling your provider, try the suggestions listed below.

3. Run VoIP Connectivity and Speed Tests

To remedy potential issues and optimize your VoIP network, you first need to know what’s wrong. The quickest way to determine a problem is by running speed and internet connectivity tests on your network. VoIP tests measure the speed, jitter, and latency of your internet connection. Similarly, you can even use a ping test to assess where exactly is the delay or issue occurring within your network or phone system.

Now, some VoIP providers offer their own tools that you can use. But others will direct you to different tools that they trust. Check with your provider about what they recommend or look online for internet, ping, and VoIP tests.

4. Identify VoIP Issues

After you run these tests, you’ll get scores for latency, jitter, packet loss, upload speed, and download speed. This will give you a clear idea of how your network is performing. If any of these scores are outside the acceptable range, you will experience issues with call quality.

Another way to identify VoIP issues is by manually monitoring call quality for jitter, delays, audio issues, etc. You can use MOS scores to get user opinions of a call’s quality – something like this:

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

Then, you can go back and investigate each call using call detail records, activity reports, and alerts. And you can make this process more effective using a call recording feature, as you can actually listen to the calls with low MOS scores to identify the issue.

Once you determine if the issue is latency, jitter, delays, audio problems, etc., you can fix it. Our VoIP troubleshooting guide (linked above) has different solutions you can implement to resolve these issues.

5. Increase Bandwidth

For voice services and VoIP calls, you need at least 85-100 kbps per call. This number increases when you have additional, concurrent calls. And all of this does not factor in other internet usage and traffic, such as streaming, checking emails, running chat, etc.

Refer to the below table to calculate how much bandwidth you will need for concurrent voice calls:

Number of Concurrent Calls	Bandwidth Recommended
1	100 Kbps
5	500 Kbps
10	1 Mbps
15	1.5 Mbps
20	20 Mbps

So, if your business does not have adequate bandwidth, your VoIP network won’t be optimized, and you’ll experience network congestion. As a rule of thumb, try using only 80% of your available bandwidth for all internet-related activities, VoIP calling included. And when you begin to exceed that limit, upgrade your bandwidth.

6. Invest in Quality Hardware

Another way to upgrade your VoIP network is by updating your hardware and equipment. Outdated, legacy equipment may have limited functionality and can degrade over time. Plus, newer software and technologies work better with newer hardware. Consider making the following upgrades if you don’t already have them:

Cabling — Use Cat 5e, Cat 6, or Cat 7 Ethernet cables.

Power — Use a Power over Ethernet (PoE) switch for efficient delivery of data and power to over one wired connection

Infrastructure — Switch to wired connections if currently using WiFi.

Routers — With features like

• Dual and Tri-Band Frequency — Transmit traffic at 2-3 frequencies, so you can separate VoIP traffic from others.
• MU-MIMO — Multi-user, multi-input, multi-output that enables each device to have its own data stream connected to the router.
• WiFi 5 (802.11ac) or WiFi 6 — Higher the wireless, the better.
• VoIP QoS — Prioritize voice traffic over other traffic.

IP devices — Deskphones, computers, and laptops built to support web calling.

7. Consider Creating a VLAN

Finally, consider adding a VLAN or virtual LAN on top of your existing internal local network. Then, you can put VoIP devices on the VLAN and all other traffic on the LAN. And you can configure the VLAN to give the highest broadcast priority to voice packet transmission by applying QoS settings via VLAN tagging.

VLAN tagging tells which packet belongs to the VLAN specifically and can help separate voice traffic from other traffic passing through your network. Your internal IT team can help you set this up within your infrastructure. However, you can also work with your ISP for professional help.

Optimizing VoIP for Business Communication

VoIP phone systems go a long way to ensure your business can communicate with customers reliably. And this is why many B2B enterprises choose to add IP telephony to their communication stack. But that includes setting it up properly and checking every now and then for potential issues.
