What is SIP Trunk Services?

Session initiation protocol (SIP) is a service that involves sending voice and other types of communications over the internet. SIP became more popular over the old Public Switched Telephone Network (PSTN) that most businesses relied on. 

The problem with PSTN is that there needs a physical connection between two points to complete means of communication. This means that calls relied on traditional copper phones phone lines. 

SIP Trunks are phone lines that utilize the internet to receive and make phone calls. This means you can make phone calls all over the world with ease and not having to be patched through an extension.

SIP trunks rely on a packet switch network. Packet switch networks break down voice calls into digital packets, which are sent through a network to the final call destination.

Without SIP trunking, your business will need to rely on separate pieces of data and voice communication. These old systems aren’t able to handle large volumes of calls. This will eventually lead to problems with a business’ continuity and customer service reliability.

SIP Trunking is fast and reliable. You can quickly initiate call routing and recording, use multimedia messaging, instantly exchange data, and hold video conferences.
