Hello!

I'm facing a problem with a call scenario with an in-dialog INVITE just after the call has been picked up.
Freeswitch receive on his leg B this in-dialog INVITE. Not forwarded to leg A.
In a SIP trace, I can see 406 Not Acceptable on leg B whereas there is no difference in the Media except "Bandwidth Information" which is "AS:80" versus "AS:82" in the RE-INVITE.
I turn on the logs on debug, but nothing specific appears. The first thing:
3f6d8dd1-5415-4a58-a948-551d841cf5dd 2021-06-11 10:34:12.873542 [NOTICE] sofia.c:1012 Hangup sofia/internal/ABC [CS_EXCHANGE_MEDIA] [NORMAL_CLEARING]

Is there any reason for this? SDP is not duplicated, but there is no specific reason for replying with 406.

Regards,

Igor.

Try getting a trace for the call.

Hi David,

I got a SIP trace. Do you think of another kind of trace? Something in addition of log level debug?

Regards,

Igor.

I hadn't registered this:

Freeswitch receive on his leg B this in-dialog INVITE.




is the codec coming from that re-invite acceptable by fs? " 406 Not Acceptable" usually means FS doesn't support the offered codec.

Hi David,

On the top of the list yes. I just see that g729 is added and his not supported. But there is at least 1 codec supported.

Regards,

Igor.

Try forcing it to your supported codec

note that reply "406 Not Acceptable" is not the same as "488 Not Acceptable Here".  Try a "sofia loglevel all 9" to get more information.

Hello,

I had a similar issue with a direct 406. With sofia loglevel all 9, I could catch:

That doesn't relevant for me. Does it for you?
