[Freeswitch-users] Call drop with 406 after being answered

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

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:

switch_core_session.c:2815 sofia/lega/+FROM at W.X.Y.Z. skip receive message

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