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.
Claims17
A telecommunications system configured to respond to pulse and dual tone multi-frequency (DTMF) dialing comprising:
- means at a telecommunications switch for setting up a call between a first telecommunications device and a second telecommunications device;
- means associated with said telecommunications switch for monitoring whether the call from the first telecommunications device is from a DTMF or pulse type device;
- and
- means for automatically providing a signal to said second telecommunications device indicative of whether said first telecommunications device uses DTMF dialing.
A method for calling in a telecommunications system, comprising:
- setting up a call via a switch between a first telecommunications device and a second telecommunications device;
- monitoring at said switch whether the call from the first telecommunications device is from a DTMF or pulse type device;
- and
- automatically providing a signal to said second telecommunications device indicative of whether said first telecommunications device uses DTMF or pulse dialing.
A telecommunications system configured to respond to a first and a second type of dialing comprising:
- means for setting up a call between a first telecommunications device and a second telecommunications device via a switch;
- means associated with said switch for monitoring whether the call from the first telecommunications device is from a device employing said first type of dialing or said second type of dialing;
- and
- means for automatically providing a signal to said second telecommunications device indicative of whether said first telecommunications device uses said first or second type of dialing.
A telecommunications system configured to respond to a first and a second type of dialing comprising:
- a dialing interface at a switch adapted to receive said first or second type of dialing from a first telecommunications device;
- and
- a controller operably coupled to said dialing interface and adapted to automatically provide a signal to a second telecommunications device indicative of whether said first telecommunications device uses said first or second type of dialing.
A telecommunications switch configured to respond to a first and a second type of dialing comprising:
- a dialing interface adapted to receive said first or second type of dialing from a first telecommunications device;
- and
- a controller operably coupled to said dialing interface and adapted to automatically provide a signal to a second telecommunications device indicative of whether said first telecommunications device uses said first or second type of dialing.
