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

[Visciano Giovanni]

Finally we are back to our test.
I updated my FS installation to last GIT
(FreeSWITCH Version 1.0.head (git-eae86e0 2011-11-30 18-14-24 -0600))

TEST
----
SIP vs SIP basic audio call, then re-INVITE for codec modification.
FS configuration B2B, avoid transcoding.

CONF
----
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"/>

Loaded codec modules:
freeswitch at internal> show codec
type,name,ikey
codec,G.711 alaw,CORE_PCM_MODULE
codec,G.711 ulaw,CORE_PCM_MODULE
codec,G.729,mod_g729
codec,PROXY PASS-THROUGH,CORE_PCM_MODULE
codec,PROXY VIDEO PASS-THROUGH,CORE_PCM_MODULE
codec,RAW Signed Linear (16 bit),CORE_PCM_MODULE


TEST 1)
-------
1001  ----invite(pcma)----> FS --invite(pcma)-->  1000
1001  <----200OK(pcma)----  FS <--200OK(pcma)--   1000
1001  --re/invite(g729)---> FS
1001  <----488------------  FS

Note: FS does not negotiate end to end the reINVITE O/A codec modification.
It is closed locally on the 1001->FS leg. From the log I see
2011-12-01 15:54:13.871332 [DEBUG] sofia_glue.c:4767 Audio Codec Compare [G729:18:8000:20:8000]/[PCMA:8:8000:20:64000]

TEST 2)

1000  ----invite(pcma)----> FS --invite(pcma)-->   1001
1000  <----200OK(pcma)----  FS <--200OK(pcma)--    1001
1000                        FS <--re/invite(g729)- 1001
1000                        FS ------------------> 1001

It is closed locally on the 1001->FS leg. FS select locally G729 but this result in transcoding!
I hate transcoding!
