DTMF Decoding | Telit Cinterion IoT Developer Community

I try to decode DTMF signals on a Cinterion PH8-P modem during a voice call:

1.Enable event reporting:


2. Doing a MO voice call


3. Sending DTMF signals from the called phone/modem

In the standard audio mode detection rate is poor. When I switch to audio mode 6 via


detection rate becomes much better. Are there other audio settings which can have effects on DTMF decoding?

Thanks in advance,
