I want full duplex universal driver for modem. I m developing an IVR application using Telephony API tapi3 of Windows and i need full dulex tsp(telephony service provider)to work with (rockwell) modem, though its documented in Platform SDK that unimdm works with almost all modems. But the problem is that it support half duplex voice modems or data modems and i need full-duplex modem to allow voice-enabled menus such that a user could be able to listen its emails on normal telephone using digit keys (i.e. by detecting DTMF tones) my application will be allowing user to browse through and read the emails in his/her mailbox and also allowing the user to record void messages.
The project involves tapi/mapi/sapi.
The problem i m facing with is tapi.
I have developed the application that enumerate through the available addresses and then bound on the address that support the media type “audio” and then listens for incoming calls through PSTN network but it doesnt bound “phone calls” i.e.LINEADDRESSTYPE_PHONENUMBER
address and says “couldnt find an appropriate address for this address type”.
the application works for H323 calls
only.
Please help me if one can.
