[Freeswitch-users] Problem sending DTMF using an FXS channel

Hello,

 

I’m having trouble with calls to remote IVR using DTMF, when the A leg is an
FXS port.

 

What happens is when the key is pressed on the phone, the DTMF is sent
inband to the callee party as voice, but also detected by freeswitch and so
resent by freeswitch to the callee party. This results in unusability of
called IVR.

 

Is there any setting that could be used to prevent freeswitch from detecting
DTMF and/or prevent freeswitch from resending the DTMF.

 

Thanks

 

François
