I'm having an issue with my DTMF to a Docker container running FS 1.6.9. My sofia profile is set up to use RFC2833. However from a softphone and another FS server it's not detecting the digits. If I switch to INFO method, it works fine.

Also is there a quick was to do a uuid_send_dtmf using SIP INFO to work around this issue temporarily? I saw something about a channel variable dtmf_type, which didn't seem to work when I did a uuid_setvar.

Thanks,

Danny Gershman
