maddr patch (was Re: [Serdev] Re: [Sems] Stale CSeq Value with BYE

[Ulrich Holeschak]

Hello,
thanks for the hint with subst_uri, i didn't know that this command is
existing.
But i had to modify your regular expression a bit, i think you forgot that
the port is written behind the host name as in this example:

sip:494755 at router.local:14039;maddr=192.168.42.242;transport=tcp

You expression won't match because you don't match the port (:14039) part.

Now i use:

        if
(subst_uri("/(sip:)([a-zA-Z0-9_.!~*'()%&=+$,;?-]+@)?([a-zA-Z0-9.-]+)(:[0-9]+
;.*)(maddr=)([0-9.]{7,15})/\1\2\6\4\5\6/"))
        {
                log("destination replaced with maddr\n");
                route(1);
                break;
        }

this works well ...

This creates:
sip:494755 at 192.168.42.242:14039;maddr=192.168.42.242;transport=tcp
and leaves the port untouched.

In my expression before i have removed the 494755@, i am not sure if this is
a problem.

Thanks,

Ulrich
