[OpenSIPS-Users] Occasional registration handling errors

[Bogdan-Andrei Iancu]

Hi Chen-Che,

The problem is because you handle the SIP traffic in a stateless way 
(basically the re-transmission is handled as any request) while the auth 
module keeps state for the nonce (and there is a different between the 
original invite and the retransmission).

What you need to do is to place a "t_newtran()" before doing the auth - 
this will discard the retransmissions as forcing opensips to go in 
stateful mode.
