Frequently Asked Questions

What is a SIP Trunking Service?

SIP trunking service connects your PBX system or unified communications platform to the public switched telephone network (PSTN) over an internet connection. Instead of using traditional phone lines, it sends voice calls, video conferencing, messaging and SMS over a single IP connection. It offers cost-effective outbound calling and inbound toll-free numbers while maintaining real-time call quality and uptime.

Unlike many SIP trunking service providers, iTeraTEL owns and operate our own network and are fully licensed as a proposed competitive local exchange carrier (CLEC) by the Canadian Radio-television and Telecommunications Commission (CRTC).

A SIP trunk can handle multiple calls at once, depending on the number of channels assigned. Each channel supports one incoming or outgoing call and businesses can scale the number of channels based on call volume.

The primary benefits of SIP trunks compared to Primary Rate Interface (PRI) are cost savings, cloud flexibility, and scale. Because SIP trunks are elastic, businesses can scale SIP services up and down to meet demand easily.

In addition, cloud-based voice like SIP removes the need for fixed overhead costs and on-premise equipment. The infrastructure costs for SIP trunking are also lower because SIP eliminates the need for primary rate interfaces (PRIs), which requires enterprises to buy lines in bundles of 23. PRI customers who need 10 lines have to buy a bundle of 23, leaving 13 unused. SIP trunking, however, can be purchased in whatever number of units a business requires.
