[OpenSIPS-Users] B2B and "404 Not here"

[Bogdan-Andrei Iancu]

Anton, maybe your INVITE is looping on B2BUA - can you check on lo 
interface if opensips is not sending the INVITE to itself before begin 
sent out? Like:
    UAc --> OpenSIPS B2BUA (VIA1) -> OpenSIPS (VIA1, VIA2, RR1) -> UAS

you can do "ngrep -d lo . port 5060" to check

Regards,
Bogdan
