I implimented an octel menu with 3 options. This is a Octel 250. The call comes in through an 800 line and is programed on a nortel switch 81c. The number is a phantom and points to Octel with direct call forward on it to octel. When a caller enters one of the options a message says please hold and a wait of about 15 seconds of dead air is heard. Can thus dead air be eliminated? The calls are calling in and are hanging up because of dead air.
