[Serusers] gateway config help! - sr-users

13 May 2003

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:
...

 6(13970)  uri:     <sip:452564@10.1.1.22>

 6(13970) DEBUG: sl_filter_ACK : local ACK found -> dropping it!

If you see something big, please let me know.
THanks.
