<span style='font-family:Verdana'><span style='font-size:12px'>Hi Peter,<br />
<br />
My goal is to disable core DTMF detection completely and try spandsp instead since duplicate digit detection in the core works bad for me. DTMF in inbound call are inband.<br />
<br />
Thanks / Mike<br />

You probably get both inband and RFC2833 DTMF. So don't enable DTMF tone detection at all, and let FS parse out the RFC2833 DTMF events.

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
