Your phone is offering exactly ZERO audio codecs... and only DTMF. /b On Nov 30, 2010, at 10:56 AM, Thomas Mueller wrote:
hi
wanted to use G.722 with a Siemens Gigaset C470IP. It was all the time using G.729 so i've removed all codecs but G.722 in codec list. which lead me to INCOMPATIBLE_DESTINATION.
output of "/log 7" on fs_cli

This leads me to the maybe inaccurate conclusion that Siemens Gigaset sends 101 for G.722 what freeswitch translates to telephone-event (according to vars.xml 101 is telephone-event).
Reading further http://wiki.freeswitch.org/wiki/RTP_payload_list G.722 should have id 9.
Am I right, that Siemens is wrong?
