hmmm, so after doing a git bisect, I found that the following commit breaks the dtmf detection using flowroute commit 56d83d1967a4d3e278de72887587c767a82364ba Author: Anthony Minessale <anthm@freeswitch.org> Date: Thu Oct 8 13:17:24 2015 -0500 FS-8321 #resolve [BEHAVIOR CHANGE Add variable media_mix_inbound_outbound_codecs to mix inbound and outbound codecs] Now I do have that variable set just before the bridge <action application="export" data="media_mix_inbound_outbound_codecs=true"/> So, am I doing something wrong or what? Thanks. Michael Jerris <mike@jerris.com> wrote:
The sip trace would indicate otherwise. I would confirm for sure they are not getting what you are sending, if so, something is in between you and them modifying the sip traffic, most likely a sip alg on a router or firewall. If so, try disabling that. Also, you might want to review your codec settings as you are transcoding in this case for no reason, you might want to switch around settings to minimize this.

I don't see how this is possible, it looks like I can see those lines in the log. Any other ideas? I can do a sip trace if that would help.

look at the sdp, there was an issue with dtmf and sample rate not being 8000.

Hi. I am having dtmf problems when calling numbers via flowroute. They seem not to detect the dtmf at all. I am using 2833 in all cases. Have you done anything in say the last 4 or 5 months which might be related? I am not having these problems when using another carrier, so I am quite puzzled.
Thanks in advance for any suggestions.
