I have written a module that choose the next client reading the destination from a db, but
I can easily obtain the same scenario with the basic serial forking example:
route{
[...]
t_on_failure("1");
t_relay();
}
failure_route[1] {
append_branch("sip:number1@mygw.com");
log(1,"first redirection\n");
t_on_failure("2");
t_relay();
}
failure_route[2] {
append_branch("sip:number2@mygw.com");
log(1, "second redirection to the same gateway, but different
number\n");
t_relay();
}

Oggetto: Re: [Serusers] sequential forking and merged request
Any device implementing UA functionality should follow RFC3261. But I'm
not sure how you manage to fork off two INVITEs to the same gateway? I
would start there.

Hello,
I have a question about sequential forking and Merged Request.
If in a forking SER calls two lines of the same client (different numbers and different
Request-URIs) it refuses the second call with 482 (Cisco and Snom multiline phone for
example) according with RFC 3261 section 8.2.2.2 because the two INVITEs have the same
Call-Id, From tag and Cseq.
If this behaviour is reasonable with a phone, it could not be acceptable for other types
of client, first of all SIP-PSTN gateway.
Is it correct this RFC interpretation? Maybe is this section inappropriate for gateways?
Is there something that I can do in the config file?
