What is SIP Trunking?

TalkAssure SIP trunking is a fast and easy way to increase the number of concurrent calls you can make through one internet connection. SIP trunks remove the physical aspect of a phone line – their virtual phone lines are cloud-based and infinitely scalable.

SIP trunking provides you with added flexibility, improves business continuity and offers substantial cost-savings over traditional telephony services. By utilising SIP Trunks within a converged voice and data network, you can dynamically allocate bandwidth from voice calls to other needs such as web traffic – when you need it.

How SIP Trunking works

SIP (Session Initiation Protocol) is a signalling communications protocol used to create, manage and terminate multimedia communication sessions in an IP-based network.

A session could be a simple two-way telephone call, or it could be a collaborative multi-media conference session. Once the session is set up, further protocols/software (e.g. codecs) are required to convert the audio stream over SIP.

SIP trunking provides virtual telephone lines over a high-speed IP network, connecting to an IP PBX. In Telappliant’s case, this is a VoIPOffice (i.e. a hosted PBX). Thus, all the customer needs is a fast internet connection, and this, in turn, dictates the number of concurrent calls to be made.
