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. /Peter 18 jul 2012 kl. 21:23 skrev "Mi Ke" <mi.ke@null.net<mailto:mi.ke@null.net>>: 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.
