Chapter 1: Overview
Trunk Circuit Originated Calls
A call coming from a Trunk Circuit may be switched to either the data network as a VoIP call, a Line Circuit,
or trunk typically for connection to a termination device on the users premises such as a PBX. The routing
decision made by the Tenor CMS is based upon your configuration and the dialed number.
Figure 1-3 Trunk Circuit Call Routing
Intra-trunk Routing - “Hairpinning”
As a result of intra-trunk routing, incoming calls from a particular Trunk Circuit are switched by Tenor CMS
to be routed back out the same trunk circuit routing group.
