Table 25-2: Trunk Group Settings Parameter Descriptions
Parameter Description
Trunk Group ID
CLI: trunk-group-id
[TrunkGroupSettings_Trun
kGroupId]
Defines the Trunk Group ID that you want to configure.
Channel Select Mode
CLI: channel-select-mode
[TrunkGroupSettings_Cha
nnelSelectMode]
Defines the method by which IP-to-Tel calls are assigned to the
channels of the Trunk Group.
ï‚§ [0] By Dest Phone Number = The channel is selected according to
the called (destination) number. If the number is not located, the
call is released. If the channel is unavailable (e.g., busy), the call is
put on call waiting (if call waiting is enabled and no other call is on
call waiting); otherwise, the call is released.
ï‚§ [1] Cyclic Ascending = The next available channel in the Trunk
Group, in ascending cyclic order is selected. After the device
reaches the highest channel number in the Trunk Group, it selects
the lowest channel number in the Trunk Group, and then starts
ascending again.
ï‚§ [2] Ascending = The lowest available channel in the Trunk Group
selected, and if unavailable, the next higher channel is selected.
ï‚§ [3] Cyclic Descending = The next available channel in descending
cyclic order is selected. The next lower channel number in the
Trunk Group is always selected. When the device reaches the
lowest channel number in the Trunk Group, it selects the highest
channel number in the Trunk Group, and then starts descending
again.
ï‚§ [4] Descending = The highest available channel in the Trunk Group
is selected, and if unavailable, the next lower channel is selected.
ï‚§ [5] Dest Number + Cyclic Ascending = The channel is selected
according to the called number. If the called number isn't found, the
next available channel in ascending cyclic order is selected.
Note: If the called number is located, but the port associated with
the number is busy, the call is released.
ï‚§ [6] By Source Phone Number = The channel is selected according
to the calling number.
ï‚§ [7] Trunk Cyclic Ascending = The channel from the first channel of
the next trunk (adjacent to the trunk from which the previous
channel was selected) is selected. This option is applicable only to
digital interfaces.
ï‚§ [8] Trunk & Channel Cyclic Ascending = T
Trunk Cyclic Ascending and Cyclic Ascending methods to select
the channel. This method selects the next physical trunk in the
Trunk Group, and then selects the B-channel of this trunk
according to the Cyclic Ascending method (i.e., selects the channel
after the last allocated channel). This option is applicable only to
digital interfaces.
For example, if the Trunk Group includes two physical trunks, 0
and 1:
For the first incoming call, the first channel of Trunk 0 is
selected.
For the second incoming call, the first channel of Trunk 1 is
selected.
 For the third incoming call, the second channel of Trunk 0 is
