[Freeswitch-users] Different dtmf type for different gateways in single profile

[Steven Ayre]

SIP Info doesn't show in SDP so might be harder to detect from dialplan,
I'm not sure if there's anything set that'd indicate it was in use...

You can see whether there are any useful channel variables by running the
info app or checking the xml cdr for a test call though.
