Summary: B2B - core on reply when 408

Initial Comment:
If b2b generates 408 Timeout, in b2b_reply route $mb is null and if I do
route[B2B_REPLY] {
    xlog("b2b_reply $si:$sp\n");
}
opensips crashes:

Message:
In case of timeout, there are $rr="Timeout", but $rs is NULL. It would be
helpful, if $rs="408".
I understand that it's fake call, but $rs and $rr needed for identify
reply.

So, problems:
1. Empty $rs when 408.
2. CRLF in $ci

OK, one step forward :)

The $mb is NULL as the "408" you have there is an internally generated
reply, not a real received one. So, it is a FAKED reply (just a reply code
and status) - it is actually build only when to be sent out.
As this route gives access to received replies, it is impossible to provide
a body to an internally reply.

Regarding the $ci (the ending CRLF), I will look into.

Message:
Now it not crashes, but $mb is still NULL. I think $mb should contain 408
reply.
Also why $ci ended by "\r\n" in b2b_reply?
$si, $sp point to self (ok).
