RFC2833 tones are detected but not relayed through the linphonecore api.
You'll need to hack the on_dtmf_received() function in file audiostream.c in
mediastreamer or mediastreamer2 directory according to the version of
linphone you are using (mediastreamer2 is for >=1.3.99).
Linphone can send SIP-INFO dtmfs but reception is unimplemented.

I'm sorry I don't know.
