Table 5-5: Trunk Group Table
Description
The numbers (1-8) in the Trunk ID drop-down list represent the physical trunks on the back of
the VoIP gateway.
To enable the trunk's B-channels, you must enter their number in this field.
[n-m] represents a range of channels.
For example, enter [1-24] to specify the channels from 1 to 24.
Note: The number of defined channels must not exceed the number of the trunk's B-channels
(1-24 for T1 spans and 1-30 for E1 spans).
In each of the Phone Number fields, enter the first number in an ordered sequence that is
assigned to the range of channels defined in the adjacent 'Channels' field.
Note: This field is optional. The logical numbers defined in this field are used when an
incoming PSTN / PBX call doesn't contain the calling number or called number (the latter
being determined by the parameter 'ReplaceEmptyDstWithPortNumber'), these numbers are
used to replace them.
These logical numbers are also used for B-channel allocation for IP to Tel calls, if the trunk
group's 'Channel Select Mode' is set to 'By Phone Number'.
In each of the Trunk Group ID fields, enter the trunk group ID (1-99) assigned to the channels.
The same trunk group ID can be used for more than one group of channels.
Trunk group ID is used to define a group of common behavior channels that are used for
routing IP to Tel calls. If an IP to Tel call is assigned to a trunk group, the call is routed to the
channel or channels that correspond to the trunk group ID.
You can configure the Trunk Group Settings table to determine the method in which new calls
are assigned to channels within the trunk groups (refer to Section
Note: You must configure the IP to Trunk Group Routing Table (assigns incoming IP calls to
the appropriate trunk group). If you do not configure the IP to Trunk Group Routing Table,
calls do not complete.
For information on how to configure this table, refer to Section
Enter the number of the Tel profile that is assigned to the B-channels defined in the
'Channels' field.
