[Freeswitch-users] Sofia late-negotiation on re-INVITE(codec-modification)

[Visciano Giovanni]

> You do realize that those param's are sofia profile params and not dialplan XML right?

Hi Brian, sure I know that.
So:

In sofia SIP profile I have:
  <param name="inbound-late-negotiation" value="true"/>
  <param name="renegotiate-codec-on-reinvite" value="true"/>

and in my dialplan XML I hit:
  <action application="set" data="inherit_codec=true"/>


I repeated my test scenario, sorry what I described was with
inherit_codec=false.
If I set inherit_codec=true (this is my purpose) sofia behavior is this:

INVITE [pcma,g729]    ---> FS ---> INVITE [pcma,g729]
200 OK [pcma]         <--- FS ---> 200 OK [pcma]
re-INVITE [g729]      ---> FS
Reinvite Codec Error! <--- FS

Here the call is release and from the log I see that sofia just negotiatiate
localy and compare the codec list in the new offer only with PCMA.
With inherit_codec=false it compare the codec list with the codec loaded
in the core so it match G729 (but damn it's a passthrought codec and I cannot
do transcoding!).

Here is an extract off the log, that show the error.
Now I do not have with me the complete session log, I will send it tomorrow.
Do you think it's a bug?
