SIP Trunks

Glossaries

Term	Definition
SIP Trunks	Session initiation protocol (SIP) trunks act as a bridge between a PBX and the public telephone network. If a client has their own PBX and we are supplying them with connectivity, then staff making calls would reach the public telephone network via a SIP trunk that connects to our core network. For example, if a client wanted to make a call then the call data would go from their VOIP phone to their PBX using the local network. The data would then travel from the PBX to the exponential e core network via the EDD and from the core network to the public telephone network via SIP.
