Automatic Release of Incoming Calls

An outside caller may be placed in a queue waiting for an external application to handle the call such as an Auto Attendant, IVR, ACD or other device. If the CO line for that call does not offer “disconnect supervision,” that call may remain in a holding position until forced to release the connection.

This feature provides full use of all CO lines at all times. A CO line is not tied up if the call goes unanswered and no alternative call handling is provided. This is very useful for disconnect

supervision in voice mail and built-in auto attendant applications, but availability and reliability of the signaling from the CO must be confirmed.
