What Is SIP Trunking? A Helpful Guide

de Eleanor Manning (2018-09-29)


Businesses constantly search for solutions that reduce their cost and improve their operations. With the globalized business environment, the need to have an effective communication channel has led to the advent of VoIP technologies. Over the years, the communication infrastructure has gradually evolved and nowadays you hear different jargons that are enabling businesses to implement unified communication (UC) technology.

One of the widely implemented technologies is SIP trunking. Session Initiation Protocol or SIP trunking provides companies a channel that connects their PBX to the public switched telephone network (PSTN). It enables you to have all the communication features, such as video, voice, and data on a single location in the form of instant messaging, video conferencing, voicemails, and more.

How Does it Work?

If you are already using a VoIP solution, the next reasonable step is to figure out how you can connect it to the cloud hosting service. LAN with limited bandwidth will not support your VoIP system. The limited internet speed of your existing plan will not be enough to provide a smooth flow of communication.

This is where SIP comes. It serves as an additional feature; a direct line to your SIP trunk provider that goes past the regular internet service provider. With this technology, it is better not to use a regular internet connection if you want to get a reliable and high-quality communication experience.

SIP trunking enables the delivery of a voice call, along with unified communication features using an IP network. It provides a substitute for a traditional telephony system. By using this technology, a person can make a call to a PSTN network without any telephone lines. You can set up a connection with the help of a hosted PBX solution.

There are three things you have to look at when implementing a SIP trunking technology. First of all, you need to have a telephony system that is compatible with SIP trunking. The second is a border element that acts as a bridge and provides a connection between the PSTN and the enterprise network. Last but not the least, you need to have a reliable SIP trunk provider that offers a compatible solution for your existing systems and understands the network requirement.

These elements enable the smooth functioning of your communication infrastructure and allow you to have a good communication experience.
