[Freeswitch-users] DTMF detection in the core & spandsp

[Mi Ke]

Hi All,

 Do I need to disable DTMF detection in the core when I use spandsp for the same?

 Calling stop_dtmf before spandsp_start_dtmf didn't work for me and when I dial e.g. 0 I get:

 2012-07-18 18:47:25.155435 [DEBUG] mod_spandsp_dsp.c:61 DTMF BEGIN DETECTED: [0]
 2012-07-18 18:47:25.155435 [DEBUG] mod_spandsp_dsp.c:73 DTMF END DETECTED: [0], duration = 89 ms
 2012-07-18 18:47:25.295432 [DEBUG] switch_rtp.c:3457 RTP RECV DTMF 0:2400

 which comes to 00 after digit collection completes.

 Setting dtmf-type to none in sofia profile didn't help either.

 What's the right way of switching to spandsp's DTMF ?

 Thanks in advance for all yours hints.

 Mike
