Description
Exclusive
Only the channel specified for the call is acceptable.
Preferred
The remote switch can select a different channel if the one specified for the call is not acceptable for some reason.
Default
: Exclusive
NOTE: Preferred channel selection is normally used by the client-side switch to have the network-side switch choose the channel
used for a call. This allows the network side to select the channel used for incoming calls as well as the channel used for
out outgoing calls, thus preventing the possibility of glare conditions.
