• 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
5.8.7
on page 60 . 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.
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.
