[Freeswitch-users] ERROR 404 BAD HEADER

This is somewhat speculative, by I think we have evidence that the final OK
is received.


In the past with NAT issues where the responses are not being received by
the client, the CSeq does not get incremented and I get reoccurring "CSeq: 1
REGISTER" packets. Here we see CSeq 1,2,3 (all pefect) and then a CSeq 4
recv starting over that has errors.  Since the CSeq increased, I have a firm
hypothesis that the Cseq 3 response was received.


But I agree a sip trace on the client end would be definitive.

I think we've established that the device is misbehaving. The only thing I
have to wonder about is if the device receives the final 200 OK in the
original REG dialog. If it doesn't then I could imagine it "trying harder"
by sending registrations to other IP/port combos. (I don't condone that
behavior, just that I understand why a device might do that.)

Can you get a SIP trace from the device that is attempting to register? It
would be extremely helpful for you to see what that device is seeing.

Hello Sean,

If it is issue with router then it also should not work for the voip.ms
account. I can register extension voip.ms but not with my server.

Is there anything else do you know which adding port twice in contact
