SIP - What is a SIP Trunk

What is a SIP Trunk?

SIP trunking is Voice over Internet Protocol (VoIP) and streaming media service based on the Session Initiation Protocol (SIP); which Internet telephony service providers (ITSPs) deliver telephone services to customers equipped with SIP-based private branch exchange (IP-PBX) and Unified Communications facilities.
With SIP trunks their is two different terminologies used to describe the number of possible calls. These different terms are “trunks” and “channels”, and often used interchangeably. That being said, from a technical configuration stand point a trunk is the connection and channel is a line.

General terminology applied to our service

By default all of our SIP plans come with 1 trunk and 1 channel; allowing you to make and receive up to 1 calls at the same time. These calls can be to or from any number assigned to your trunk. The number of channels per trunk can be increased based on your requirement; and most telephone systems allow you to have multiple trunks for more flexibility.
