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. -----Messaggio originale----- Da: Charlie Orford <charlie.orford@attackplan.net> Inviato il: 24 Nov 2011 - 13:47 A: FreeSWITCH Users Help <freeswitch-users@lists.freeswitch.org> Hi Chris, I've increased the debugging and taken a new trace: http://pastebin.freeswitch.org/17864 And here is the output of tport_sip.log: http://pastebin.freeswitch.org/17865 A person on the #freeswitch IRC channel suggested the problem might be due to packet fragmentation?

Hi list
I have done some googling but cannot find much info about what causes FS to send a SIP/2.0 400 Bad Request response.
My phones are able to register but when I try a test call (e.g. to 9196) FS responds to the INVITE with Bad Request. For a short transcript of this in action see: http://pastebin.freeswitch.org/17863
My setup: I have a clean git head install (cloned yesterday) and am running the unmodified "out of the box" configuration (except I have enabled NDLB-force-rport on the internal profile and set a default poassword). FS is on a public server (no nat) and phones (aastra 57i models) are all natted behind an ADSL router.
Thanks & Regards, Charlie
