We tried some standard call flow of Voiceguide, found that the system can detect the DTMF key we entered if we use mobile phone to call, but cannot detect the DTMF key we entered if we use a land line analog phone to call. Seems the Dialogic board has problem to detect DTMF if we call from a landline analog phone, which generate the DTMF tone by the telephone, not by the Telco (in mobile phone communcation, the DTMF tone should be generated by the telephone company?) Is there any parameters in the configure file we can change?
We did not encounter the same problem if we run other IVRS application development by our company. Therefore, I think the problem is caused by Board parameters or Channel parameters settings?
