DTMF tone signals

snhnic

If just installed IVM answering and in the simulation it works fine, but when someone calls and pressing the option sya number 1 nothing happens, IVM does not respond. It seems the modem is not picking up the dtmf tones from the caller? The modem is half duplex I don't know what to do? Can somebody help? Because the software seems to doing waht i like in the simulation.

Please read www.nch.com.au/ivm/modems.html for more information about modems and IVM. IVM responds to TAPI commands, which are delivered by your modem's drivers. Try updating your drivers and see if that helps. We must emphasise that we cannot 100% guarantee the compatibility of any particular modem because of this driver issue.

Even a voice modem requires compliant TAPI drivers. Go to the Windows Control Panel double click on the Multimedia and pull down the "Audio - Sound Playback" list. Your voice modem should be listed. If it is not listed then voice modem TAPI drivers are not installed. When this happens the IVM messages are delivered over the computer speakers even when an actual call is answered

I don't see multimedia in the controlpanel. How can I check the tapi drivers?

I've tried five different modems all voice capable. 3 intern and 2 extern everyone off them has the same result. no respons on keypress. The modems are all with different chips. Conextant, Lucent and some others. So it must be the software, is there some way to test the key press, perhaps with hyperterminal? How do I make connectuion to see if there is a respons when a key is pressed? Could it be the phone provider? When on normal phone a caller presses a key I hear a tone, so the tones are coming in over the line. Could i t be a different sound form the provider? I'm in Holland with @[deleted] telephony as provider, they have a FSK signal. Is there a way to test things?
