[Users] ovpops for serial forking and its cures

[Bogdan-Andrei Iancu]

Hi Francesco,

so you have a PSTN to SIP call - does your OpenSER require 
authentication for GW? or the "407" is not generated by OpenSER?

in the auth block, skip from auth the request coming from the GW IP.

if (src_ip!=gw_IP) {
    #perform auth
    .....
}

My goal is to have one PSTN number mapped to N voip number; so, when the first voip number is busy, OPENSER catch 486 reply and then try with the second AOR and so on. But here raise the problem: the OPENSER forward the reply upstream with a code 407 Proxy Auth Required and the PSTN GW send his ACK and all stop here.
