DTMF = Dual Tone Multiple Frequency IVR = Interactive Voice Response For example, If I use NetMeeing call a IVR behind a H323 gateway. I can here the prompt voice of the IVR process, such as "press number 1 for Chinese language service ,and number 2 for English language service ..." ,etc But I can't go on with this IVR, because I can't press number 1 key just as on a normal phone pad. All I can do just spead to my microphone. How can I send a number 1's DTMF to the IVR ??? If anybody can give tips , I would greatly appreciate.
