An extension user can leave a Trunk Callback for many trunks. The system processes the callbacks
as the trunks become free. In addition, many extensions can leave a Trunk Callback for the same

If an extension user leaves a Trunk Callback request and then fails to answer the callback ring
within four rings, the system cancels the Callback.
