Abstract
A system whereby automatic dial-type recognition is employed to reduce the wait time for callers and prevent false identification of touch tone versus dial tone service. A system according to the present invention includes a control unit (103) located in a PBX (104) or other switch which detects whether a caller is placing a call using pulse or DTMF dialing. The control unit (103) in the PBX (104) generates a message during call setup which it provides to the remote system, such as an interactive voice response system.
