[Freeswitch-users] Siemenst C470IP and G.722

[Thomas Mueller]

  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?
