Hello,
first, write a proper regular expression. The expression should match
hostname AND IP address of your server in the domain. Also don't forget
to put backslashes before dots because dots are substitution characters
in regular expressions. You can use for example something like this:
if (uri=~"sip:[0-9]+@(your\.domain|10\.1\.1\.22)") {
t_relay_udp("10.1.1.240", "5060");
break;
};
This will forward messages containing a number in the username part to
your PSTN gateway.

Hi,
I'm doing a few tests to try SER.
I use a simple configuration:
-two Cisco ip phones
-one Cisco 1760 Voice gateway with ISDN interfaces.
Calling between the ip phones works, but going through
the Voice Gateway is something else... I don't really
understand how to edit the config file, and I suppose
their's a simple way. Here's how I tried.
I added these lines to the default config:
if (uri=~"^sip:452564@10.1.1.22") {
t_relay_to("10.1.1.240","5060");
break;
};
And I call always teh same number 452564. 10.1.1.240 being
my gateway, and 10.1.1.22 the SIP proxy server.
An extract of the debbuging info:
