[Serusers] uri==myself check and record_route()

[Maxim Sobolev]

Folks,

I am correct that it is impossible to use uri==myself check along with 
record_route()? That is, consider the following situation:

UA1->SER (with record_route())->UA2

UA1 sends INVITE to SER:

INVITE sip:ua2 at ser.ip
Contact: <sip:ua1 at ua1.ip>

After processing SER resends it to UA2:

INVITE sip:ua2 at ua2.ip
Record-Route: <sip:ua2 at ser.ip;lr>
Contact: <sip:ua1 at ua1.ip>

Then, if UA2 wishes to terminate session it sends the following BYE to 
the SER:

BYE sip:ua1 at ua1.ip
Route: <sip:ua2 at ser.ip;lr>
Contact: <sip:ua2 at ua2.ip>

Therefore if there any

if (!(uri==myself)) {
   sl_send_reply("500", "example serves only my domain");
   break;
};

checks in the SER, it will reply with 500 to UA2, not allowing 
transaction to go through.
