Trunk Groups
As the name implies, a trunk group is a group of trunks. If a call is routed to a trunk group, OBi picks one of the available
trunks from the group to make the call. Availability of trunk is based on:
- Whether the trunk’s digit map allows the number to call, AND
- Whether the trunk has capacity to make one more call
Up to 4 trunk groups can be configured on an OBi device. Each trunk group is conceptually another trunk with its own
DigitMap. A trunk group and its associated DigitMap are referenced using the short name TG
n and (Mtg n ) respectively,
where n = 1, 2, 3, 4. They can be referenced in other digit maps and call routing rules so that calls may be routed to a
particular trunk group.
Only trunks can be added to a trunk group. These include: PP1, SP1, SP2, SP3, SP4, LI1
1
, VG1, VG2, …, VG8, TG1, TG2, … TG4.
Note that a TG may include another TG (that is, TG can be recursive). However, you must make sure this does not result in
infinite recursion.
Trunk Group Parameter Guide:
Parameter Description Default Setting
Trunk Group n ( n =1–4)
Enable Enable this trunk group Yes
Name An arbitrary user friendly name to identify
this trunk group (optional)
TrunkList A comma separated list of names of trunks
to include in this trunk group. For TG1, the default for
OBi100 and OBi110 is:
sp1,sp2
and for OBi202 is:
sp1,sp2,sp3,sp4
For other TG, the default is
(blank)
DigitMap Digit map associated with this trunk group. It
can be referenced as (Mtg
n )
For TG1, the default is
(1xxxxxxxxxx|<1>[2-9]
xxxxxxxxx|011xx.|xx.)
For other TG, the default is
(xx.)
