Term Definition
Software as a Service

Software as a Service (SaaS) is a software delivery method over the Internet. The software is hosted remotely, so organisations do not need to invest in additional hardware. Software as a Service removes the need for organisations to handle the installation, set-up and often daily upkeep and maintenance, meaning leaner and more responsive IT resources.

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.

Session Initiation Protocol

Session Initiation Protocol (SIP) enables calls to be routed via the Internet rather than a telephone Network.
