[Freeswitch-users] How to disable FS DTMF detection

[Adrian Worutowicz]

Hi,

I've tried and failed.

When I press any key on the phone keyboard, the other end hears some residual DTMF sound and in the console I get:

2019-02-19 15:50:50.070836 [INFO] switch_channel.c:515 RECV DTMF 3:1760
2019-02-19 15:50:51.350964 [INFO] switch_channel.c:515 RECV DTMF 6:1920
2019-02-19 15:50:52.390068 [INFO] switch_channel.c:515 RECV DTMF 9:1760
2019-02-19 15:50:52.470076 [INFO] switch_channel.c:515 RECV DTMF 9:1112

I want the DTMF tones to pass freely from one phone to another with no interference.

Thanks,
Adrian.

Hi,

You need to put the
  <param name="pass-rfc2833" value="true"/> in your sip profile like all other params.

It is not necessary however as you can just put
  <action application="export" data="pass_rfc2833=true"/> in your dialplan, notice the export instead of set.

The spandsp_stop_dtmf only works for inband dtmf, not the rfc2833 one.

Hope this helps.
