reliable responses.
[0] Disable
[1] Supported (default)

Notes:
The Supported and Required headers contain the '100rel' tag.

received with '100rel' in the Supported or Required headers.
Port (channel) allocation algorithm for IP-to-Tel calls.
[0] By Dest Phone Number = Selects the device's channel according to
the called number. (default.)
[1] Cyclic Ascending = Selects the next available channel in an
ascending cyclic order. Always selects the next higher channel number
in the trunk group. When 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.
[2] Ascending = Selects the lowest available channel. It always starts at
the lowest channel number in the trunk group and if that channel is not
available, selects the next higher channel.
[3] Cyclic Descending = Selects the next available channel in
descending cyclic order. Always selects the next lower channel number
in the trunk group. 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.
[4] Descending = Selects the highest available channel. Always starts at
the highest channel number in the trunk group and if that channel is not
available, selects the next lower channel.
[5] Dest Number + Cyclic Ascending = First selects the device's port
according to the called number. If the called number isn't found, it then
selects 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.
[6] By Source Phone Number = Selects the device's channel according
to the calling number.
[7] Trunk Cyclic Ascending = Selects the device's port from the first
channel of the next trunk (next to the trunk from which the previous
channel was allocated.
Notes:
The internal numbers of the device's B-channels are defined by the
TrunkGroup parameter.
For defining the channel select mode per Trunk Group, refer to
''Configuring the Trunk Group Settings'' on page 197.
