The system can provide a pseudo-CO dial tone to prevent possible confusion to station users. Users hear dial tone to simulate that they have accessed a line outside the system (for example, by dialing 9).
Second dial tone is not available unless you enter a partial or complete external number in the "Digits Dialed" field of the ARS Digits Dialed form.
Enable Second Dial Tone in
the ARS
Leading Digits form.
