Hello, I am trying to use wiki config about iLBC codec but I am not be able to make it work. If I configure codec prefs as: <X-PRE-PROCESS cmd="set" data="global_codec_prefs=GSM,PCMU,PCMA,iLBC"/> I get: ------------------------- 2010-10-01 08:48:22.444357 [DEBUG] sofia_glue.c:3867 Audio Codec Compare [iLBC:97:8000:30]/[GSM:3:8000:20] 2010-10-01 08:48:22.444357 [DEBUG] sofia_glue.c:3867 Audio Codec Compare [iLBC:97:8000:30]/[PCMU:0:8000:20] 2010-10-01 08:48:22.444357 [DEBUG] sofia_glue.c:3867 Audio Codec Compare [iLBC:97:8000:30]/[PCMA:8:8000:20] 2010-10-01 08:48:22.446360 [DEBUG] switch_core_state_machine.c:314 (sofia/internal/dsp1@174.36.98.82) Running State Change CS_NEW 2010-10-01 08:48:22.446360 [DEBUG] sofia_glue.c:3867 Audio Codec Compare [iLBC:97:8000:30]/[iLBC:98:8000:20] ------------------------- Phone offers 30 ms, FS 20 ms and call gets cursed...
