Valid Range and Description

ChannelSelectMode

[Channel Select Mode]

Defines common rule of port allocation for IP to TEL calls.

0 = By phone number - Select the gateway port according to the called number

(refer to the note below).

1 = Cyclic Ascending - Select the next available channel in an ascending cycle

order. Always select the next higher channel number in the Trunk Group. When
the gateway reaches the highest channel number in the Trunk Group, it selects
the lowest channel number in the Trunk Group and then starts ascending again
(default).

2 = Ascending - Select the lowest available channel. Always start at the lowest

channel number in the Trunk Group and if that channel is not available, select
the next higher channel.

3 = Cyclic Descending - Select the next available channel in descending cycle

order. Always select the next lower channel number in the Trunk Group. When
the gateway reaches the lowest channel number in the Trunk Group, it selects
the highest channel number in the Trunk Group and then start descending
again.

4 = Descending - Select the highest available channel. Always start at the

highest channel number in the Trunk Group and if that channel is not available,
select the next lower channel.

5 = Number + Cyclic Ascending – First select the gateway port according to the

called number (refer to the note below). If the called number isn’t found, then
select the next available channel in ascending cyclic order. Note that if the
called number is found, but the port associated with this number is busy, the call
is released.


Note:

The internal numbers of the gateway’s B-channels are defined by the

‘TrunkGroup_x’ parameter (under ‘Phone Number’).
