Rather than pay for peak capacity all year round, you can scale up or down your Public Switched Telephone Network (PSTN) connectivity service, depending on how busy you are.

Session Initiation Protocol (SIP) is used to provide voice over IP (VoIP) connectivity between a Private Branch eXchange (PBX) and the Public Switched Telephone Network (PSTN). Global SIP is an alternative to Integrated Services Digital Network (ISDN30) that uses your data network to route your PSTN traffic. It can help improve organisational flexibility, offer additional resilience and operational efficiency whilst helping to reduce costs.
A SIP channel is the capacity needed to carry a single telephone call and is an attribute of both a trunk and a trunk group. The number of channels determines how big a trunk or trunk group is.
A SIP trunk is the connection to a PBX with a designated number of channels. This channel capacity is also called the trunk’s Call Admission Control (CAC).
A SIP trunk group in turn also has a designated number of channels and is a container for trunks. So trunks sit in trunk groups and multiple trunks can sit in the same trunk group. This capability is useful if you want to separate a set number of channels for your business or your contact centre.
Global SIP offers in-built resilience at no extra cost, routing calls to an alternative (stand-by) site if your primary site becomes unavailable. Some providers will charge for stand-by channels, but BT only charges for channels in use at any time.
