[Serusers] How SER communicate to other SIP server

[roayu]

Hi, Olaf!

Oops, I accidentally deleted the semi-colon(;) at the closing of the IF
statement. I know that the SIP messages are routed according to the URI and
that's the reason why I need to change the URI (of the TO header). But I
just failed to change the uri at the TO header. Therefore, it couldn't route
to another SIP server. 

Current FROM/TO uri that I get,
	From 	: <sip:12345 at mySER.net:5060>
 	To	: <sip:88888888 at anotherSIP.net:5060>

The actual FROM/TO uri that I WANT will be,
	From 	: <sip:12345 at mySER.net:5060>
 	To	: <sip:88888888 at anotherSIP.net:5060>

I've checked on the regular expression, and it's fine with that. Am I using
the correct function - rewritehostport()?


Thanks.

Best regards,
Roa Yu

No, SIP messages are routed according to their request URI. I am not
sure if the regular expression in your if-clause was corrupted by
the E-Mail service (if not, at least a closing bracket is missing).
I suggest, you start with a simplified version of this regexp to be
sure that the then-part is evaluated at all. Use xlog() to add a
couple of debug messages to find out which routing blocks are evaluated.
