DTMF Tones not working while making gateway calls using RMX

Please help me if any one come across this issue.

 

While making gateway calls the other side is not accepting DTMF tones while making audio calls. To the same number normal mobile phone is getting connected. RMX and HDX systems are running latest software.

Re: DTMF Tones not working while making gateway calls using RMX

  • Check that the following flags are set on your RMX :

 

GAIN_AUDIO_FOR_DTMF_FORWARDING = 8

 

ALWAYS_FORWARD_DTMF_IN_GW_SESSION_TO_ISDN = YES

 

  • Is Roll Call enabled on the IVR service used in the GW profile of the RMX , If so please disable ‘Roll Call’ and test.
