[Bayonne-devel] Unsupported Media Type, Bayonne2

[Alexandre BOULANGER]

Hi,

I was working well with a SIP IVR, running Bayonne2 1.2.0
My VoIP provider has suddenly changed the codecs used on its PSTN/VoIP
gateway, adding g729 and g729a, so my IVR cannot be joined anymore.


Here's what the gateway is sending me for SIP INVITE 

------8<---
v=0
o=- 1004590400007376 1 IN IP4 xx.xx.xx.xx
s=-
c=IN IP4 xx.xx.xx.xx
t=0 0
m=audio 4010 RTP/AVP 18 18 8 0
a=rtpmap:18 G729/8000
a=ptime:20
a=rtpmap:18 G729A/8000
a=ptime:20
a=rtpmap:8 PCMA/8000
a=ptime:20
a=rtpmap:0 PCMU/8000
a=ptime:20
a=sendrecv
m=image 4012 udptl t38
------8<---

Then I get 

IVR -> GW   SIP/2.0 100 Trying
IVR -> GW   SIP/2.0 101 Dialog Establishement
IVR -> GW   SIP/2.0 415 Unsupported Media Type
GW  -> IVR  ACK



I know ccAudio supports gsm, g.711 and g.723 codecs
I've tried to change audio encoding format in driver.conf
(mulaw,alaw,gsm) but there was no significant result:


Mar 30 08:30:26 bayonne[20741]: sip: adding sdp encoding 0 PCMU/8000

Mar 30 08:32:26 bayonne[20771]: sip: adding sdp encoding 3 GSM/8000
Mar 30 08:32:26 bayonne[20771]: sip: bound to port 5060
Mar 30 08:32:52 bayonne[20771]: sip: got bye for non-existant call

Mar 30 08:33:41 bayonne[20796]: sip: adding sdp encoding 8 PCMA/8000
Mar 30 08:33:41 bayonne[20796]: sip: bound to port 5060
Mar 30 08:33:59 bayonne[20741]: sip: got bye for non-existant call


I should at least match the PCM* encodings..
Does someone have a clue on what's going wrong?

TIA
