Have you heard about VoIP and are you unsure if it's the best option for your company? Then you must know What is VoIP and How Does it Work?

The modern way to make phone calls is using this widely used business phone service, especially for small and medium-sized enterprises looking to interact more effectively.

This blog post explains what VoIP is, how it functions, and how to choose the best VoIP provider if you're thinking about making calls without a physical landline. 

What is VoIP and How Does it Work?

VoIP may have a complicated name, but its fundamental workings are really simple. Let's examine VoIP's operation step-by-step:

Step 1 - Registration

Session Initiation Protocol (SIP) registration is a process that runs on an IP network that allows your VoIP phone or software to register with a VoIP server. Knowing that your device is online and prepared to take calls, the server logs its IP address along with other pertinent data.

When someone attempts to call you, the server knows where to route the call after your device is online and configured to accept calls.

Step 2 - Establishing a Connection

Your VoIP device makes a SIP INVITE request to the VoIP server when you dial a number. Information about the caller and the intended receiver is included in this request.

By locating the recipient's VoIP device—or, if they're using an adaptor, their standard phone—and establishing the connection between them, the server serves as a middleman.

Step 3 - Voice Data Transmission and Receiving

An analogue-to-digital converter (ADC) transforms the analogue sound waves in your voice into digital data while you talk. Next, the digital data is divided into tiny packets.

Using protocols like User Datagram Protocol (UDP) and Real-time Transport Protocol (RTP), these packets are sent across the internet. A Digital-to-Analog Converter (DAC) on the receiving end gathers the packets, reassembles them in the proper order, and converts them back into analogue sound waves.

In this case, codecs (coder-decoders) are quite important. Prior to transmission, they compress the audio data to make it easier to handle over the internet, and upon receipt, they decompress it to maintain audio quality. Frequently used VoIP codecs include G.711, G.729, and Opus.

Ultimately, your voice is heard by the recipient via the speaker or headset on their device.

Step 4 - Ending the Call

A SIP BYE message is issued to the VoIP server after the call ends and one of the parties hangs up. After that, the server ends the session, disconnects the devices, and releases the resources that were utilised during the conversation.

Understanding the inner workings of VoIP is beneficial, but as a business, all you really need is a trustworthy VoIP phone service that handles all the backend infrastructure so you can concentrate on building relationships with your clients rather than worrying about the details.

What is VoIP and How Does it Work: Equipment You Need

What is VoIP and How Does it Work: Best Practices

VoIP opens up a world of options for contemporary communication, but making the most of it takes some knowledge. Let's look at some best practices to make sure your VoIP system runs well.

1 - Recognise Typical VoIP Problems

You may frequently run into problems with bandwidth, latency, and jitter in VoIP during regular business operations.

For VoIP calls to function well, there must be enough bandwidth available. For genuine discussions, keep jitter and latency under 30 ms and 150 ms, respectively.

Audio gaps or distortions may result from packet loss, which occurs when certain data packets are unable to reach their intended recipient. Ensuring seamless communications requires a packet loss rate of less than 1%.

2 - Make Your Network More Efficient

To guarantee clear calls even when there is a lot of network traffic, use the Quality of Service (QoS) settings on your router to give VoIP traffic priority over other data.

Keep your network in good health as well. Make sure you have adequate bandwidth on your internet connection for VoIP calls and other data requirements. For more dependability, think about connecting VoIP devices over wired connections wherever available.

For best results, keep the firmware on your network equipment updated. You should also regularly inspect your network to find and fix any possible problems.

3 - Assemble Your Team And Use The Appropriate Tools.

The user experience and call quality are greatly enhanced with high-quality VoIP phones and headsets. Select dependable and cosy gear that meets the demands of your group.

Provide a quick orientation to the VoIP system for your staff. It is important for everyone to know how to use the features efficiently, as this enhances teamwork and communication.

4 - Maintain The Security Of Your System

To proactively detect and resolve such issues before they create significant interruptions, make use of monitoring technologies. For added security against unwanted access, make sure your VoIP software and firmware are up to date, use secure passwords, and turn on encryption whenever you can.

5 - Create Room For Working Remotely.

Give your remote workers precise instructions on how to set up a home office that works well for VoIP calls. This covers suggestions for setting up your computer, connecting to the internet, and turning down background noise.

For remote workers, a Virtual Private Network (VPN) can increase security and even improve call quality by encrypting their internet data and offering a more reliable connection.
