Trunk group tables
The trunk holding time for all INCALLS that are carried by trunks in this trunk group and complete during the collection interval. Trunk holding time is the length of time from the initial trunk seizure until the trunk goes idle. The trunk goes idle when the caller drops, the agent releases the call, or the communication server disconnects the call. If an incoming call on a measured trunk is transferred off the communication server, the incoming trunk remains in use for the call and accrues trunk holding time until the caller drops or the call is released.
