From what I can tell the global_codec_prefs variable is used in the internal profile, which is the profile I'm using
<param name="inbound-codec-prefs" value="$${global_codec_prefs}"/> <param name="outbound-codec-prefs" value="$${global_codec_prefs}"/> freeswitch@internal> sofia status profile internal CODECS IN G729,G7221@32000h,G7221@16000h,G722,PCMU,PCMA,GSM CODECS OUT G729,G7221@32000h,G7221@16000h,G722,PCMU,PCMA,GSM Still I don't know why FS is picking G7221 On Sun, Jan 16, 2011 at 6:45 PM, Steven Ayre <steveayre@gmail.com> wrote:
Are those variables being used in the outbound-codec-prefs or codec-prefs params in the sip profile?
What does the "sofia status profile NAME" output show for "CODECS OUT"?

Hello,
I'm experiencing some strange issue with codecs. I have the following in my vars.xml file:
<X-PRE-PROCESS cmd="set"
data="global_codec_prefs=G729,G7221@32000h,G7221@16000h,G722,PCMU,PCMA,GSM"/> <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=G729,PCMU,PCMA,GSM"/>
"inbound-late-negotiation" and "disable-transcoding" are commented in my internal SIP profile. So I guess I'm in Early Negotiation (default behavior) mode.
However, when I send a call to my provider, and I look at the SIP trace I see that FS is sending another codec, not G729 as I specified in the global_codec_prefs / outbound_codec_prefs parameters.
I'm sending calls like this:
<action application="bridge" data="sofia/internal/$1@38.102.93.70"/>
Here is a SIP trace of a call:
http://pastebin.freeswitch.org/15042
I'm not understanding why FS is sending an INVITE with the G7221 codec in line 240, if I'm telling it explicitly that I want G729 as the priority when possible in the codec prefs options. But I see G729 in the 200 OK in line 291.
I've been told to use absolute_codec_string=G729 in my dialplan or enable late negotiation, but why if I'm already telling it to use G729 in the codec prefs?
my softphone IP: 190.23.80.10 provider IP: 38.102.93.70 FS IP: 77.92.65.126
calls flow like this:
softphone -> FS -> provider
Any help appreciated.
