To use trunk groups you must also do the following:
You must assign a trunk group ID to the VoIP gateway E1/T1 B-channels on the Trunk
Group Table. For information on how to assign a trunk group ID to a B-channel, refer
to Section 5.5.7 on page 82.
You can configure the Trunk Group Settings table to determine the method in which
new calls are assigned to channels within the trunk groups (a different method for
each trunk group can be configured). For information on how to enable this option,
refer to Section 5.5.8 on page 83. If a Channel Select Mode for a specific trunk group
isn’t specified, then the global ‘Channel Select Mode’ parameter (defined in ‘General
Parameters’ screen under ‘Advanced Parameters’) applies.
¾ To configure the IP to Trunk Group Routing table, take these 6
steps:
1. Open the ‘IP to Trunk Group Routing’ screen (Protocol Management menu >
Routing Tables submenu > IP to Trunk Group Routing option); the ‘IP to Trunk
Group Routing’ table screen is displayed.

(up to 24 entries can be configured).
