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:
...

If you see something big, please let me know.
