The IP to Trunk Group Routing Table is used to route incoming IP calls to groups of E1/T1
B-channels called trunk groups. Calls are assigned to trunk groups according to any
combination of the following three options (or using each independently):
Destination phone prefix
Source phone prefix
Source IP address
The call is then sent to the VoIP gateway channels assigned to that trunk group. The specific
channel, within a trunk group, that is assigned to accept the call is determined according to
the trunk group's channel selection mode which is defined in the Trunk Group Settings table
(See Configuring the Trunk Group
'ChannelSelectMode' (see
When a release reason that is defined in the 'Reasons for Alternative IP to Tel
Routing' table is received for a specific IP Tel call, an alternative trunk group for
that call is available. To associate an alternative trunk group to an incoming IP call,

calls are assigned to channels within the trunk groups (a different method for each trunk
