GXW4104 DTMF not working


#1

We have a problem with DTMF with our GXW410X PSTN Gateway.

not all providers can pass dtmf messages to our freepbx.

Our Current Settings in the GXW410X are:
DTMF Payload Type: 101
DTMF Methods(1-7): 1

in freepbx:

disallow=all
allow=ulaw
dtmfmode=inband
dtmf=inband

Is there something that we can do to resolve the issue?

Use SIP info, it is best.
