of awaiting messages using the lamp. Or, you can choose to play a tone when

received from Cisco CallManager. If Cisco CallManager is not integrated with
your voice mail system, it does not send this information to the VG248.

Enabling Disconnect Supervision
Disconnect supervision indicates to an analog device that the remote caller has
hung up. For example, if a user calls someone with an answering machine, leaves
a message, and hangs up, disconnect supervision is the electrical state that briefly
drops the loop current and indicates to the answering machine that the caller has
hung up.
