I try to use asterisk to make automatic autobound call to do survey. this requires DTMF for feedback from people called. My setup is: asterisk--->iconnecthere---->PSTN but asterisk is unable to detect any key pressed. No information shows up in the CLI. I tried to set dtmfmode=RFC2833, info and inband. none works out. I checked the past archives, no definite answers are found.Could anybody give me a reply on this topic? Thank you! Manny _______________________________ Do you Yahoo!?
