Channel identification

Channel identification includes phone numbers and, if you have an exchange data link, line identifiers.

Phone numbers allocated to the channels can be used, in the absence of the called number being sent by the switch (using DNIS or CLID), to identify the application profile to invoke an application to answer the call. There is no need to allocate phone numbers to channels if the called number is passed by the switch. The wizard makes it easy to specify one phone number for all the channels on the trunk, or to allocate consecutive numbers.
