5.6. SIP Trunk Group

This section describes the steps for administering a trunk group for communication between

Communication Manager and Session Manager.

Step Description

Issue the command add trunk-group n, where n is an unallocated trunk group and

configure the following as shown in the display screen below:

 Group Type – Set to the Group Type field to sip.

 Group Name – Enter any descriptive name.

 TAC (Trunk Access Code) – Set to any available trunk access code.

 Service Type – Set to tie.

 Signaling Group – Set to the Group Number field value configured in Section

5.5. (i.e., 60)

two SIP trunk members for the duration of the call. The license file installed on the system

controls the maximum permitted.
