Hello. My FS receive INVITE with 2 codecs in SDP: PCMA and PCMU. After hunting dialplan, this call forwarding to IVR, and I see next message in log: 2013-01-31 01:23:22.388780 [DEBUG] sofia_glue.c:5094 Audio Codec Compare [PCMU:0:8000:20:64000]/[PCMU:0:8000:20:64000] 2013-01-31 01:23:22.388780 [DEBUG] sofia_glue.c:3077 Set Codec sofia/internal/9089080908@PSTN PCMU/8000 20 ms 160 samples 64000 bits 2013-01-31 01:23:22.388780 [DEBUG] switch_core_codec.c:111 sofia/internal/9089080908@PSTN Original read codec set to PCMU:0 And FS send 200 OK to remote side with one codec in SDP: PCMU. My parameters: In internal.xml (profile) <param name="inbound-codec-prefs" value="$${global_codec_prefs}"/> <param name="outbound-codec-prefs" value="$${global_codec_prefs}"/> In vars.xml <X-PRE-PROCESS cmd="set" data="global_codec_prefs=PCMU,PCMA,G729,G722,GSM"/> <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMU,PCMA,G729,GSM"/> <X-PRE-PROCESS cmd="set" data="inbound_codec_prefs=PCMU,PCMA,G729,GSM"/> This is normal behavior?How can I manage set of codec in inbound calls? Best regards, Alexander.
