[Freeswitch-users] Reasons for a SIP/2.0 400 Bad Request ?

[chrisbware at interfree.it]

Your INVITE is 1672 bytes. Some router split packet over 1500 bytes. To test if this is the problema, disable all codecs leaving only "basic codecs" as Aastra call them (g711a,g711u,g729) and disable ice. Packet should be smaller: if the problem is fixed in this way, packet fragmentation is the cause.

Hi Chris,

I've increased the debugging and taken a new trace:

And here is the output of tport_sip.log:

A person on the #freeswitch IRC channel suggested the problem might be 
due to packet fragmentation?

Charlie
