[OpenSIPS-Users] ERROR:registrar:update_contacts: invalid cseq for aor

[Bogdan-Andrei Iancu]

Hello Duane,

The Invalid Cseq is actually a side effect of the REGISTER 
retransmissions - you have 2 REGISTER (original + retransmission) with 
CSeq: 756 REGISTER .

First is executed in one process, gets stored and a 200 reply ; the 
retransmission gets executed in a different process, and because it has 
same cseq the storing generated the error.

You need to filter out the retransmissions (use a t_newtran() before the 
save(location) ) - it should solve the problem.

But the question is why does it take for OpenSIPS more than 500ms to 
generate the answer (and make the sender to do retransmission) ??
