http://wiki.freeswitch.org/wiki/Sofia.conf.xml#DTMF says that you can set a user variable, so e.g. when an inbound gateway ACLs as that user, you can set the dtmf type.

As per the wiki, I set: <variable direction="inbound" name="dtmf-type" value="none"/>

and do indeed see the variable in my log.

However, in the SIP 200 that FS sends back, I still see this in the SDP: rtpmap:101 telephone-event/8000

I tried with sofia loglevel all 9 (I never used that before...) but didn't really see anything related to DTMF.

Am I missing something here?
