Keypress Not Detected

[Guest Hans]

I'am in the process of evaluating IVR software and run a demo version of VoiceGuide. When using the 'Record Sound Module' it records the callers voice. When using other modules VoiceGuide doesn't detect which buttons are pressed (not even during silences). Are the DTMF sounds different per country (I am in Holland)?

DTMF tones are the same everywhere.

 

The possible reasons for VG not reacting to DTMF key presses:

 

1. The modem does not detect tem well.

2. The telephone handset used plays the DTMF tones very softly, and some modems cannot detect them..

 

Can you try using another modem and/or try calling from a different telephone handset?

Will do, thanks. I tried with two handsets already so I suspect the modem (USR, yes I know). Problem is we only have USR modems so I need to get a different one elsewhere.
