<TITLE>R: [Freeswitch-users] Sofia late-negotiation on re-INVITE(codec-modification)</TITLE>
</HEAD>
<BODY>
<!-- Converted from text/plain format -->
<P><FONT SIZE=2>Finally we are back to our test.<BR>
I updated my FS installation to last GIT<BR>
(FreeSWITCH Version 1.0.head (git-eae86e0 2011-11-30 18-14-24 -0600))<BR>
<BR>
TEST<BR>
----<BR>
SIP vs SIP basic audio call, then re-INVITE for codec modification.<BR>
FS configuration B2B, avoid transcoding.<BR>
<BR>
CONF<BR>
----<BR>
In sofia SIP profile I have:<BR>
<param name="inbound-late-negotiation" value="true"/><BR>
<param name="renegotiate-codec-on-reinvite" value="true"/><BR>
<BR>
and in my dialplan XML I hit:<BR>
<action application="set" data="inherit_codec=true"/><BR>
<BR>
Loaded codec modules:<BR>
freeswitch@internal> show codec<BR>

It is closed locally on the 1001->FS leg. From the log I see<BR>
