Hello,

to resolve the problem you describe the script would have to be executed for every branch, i.e. the last condition in your example should be executed for sip:10.20.0.100:5060 and also for sip:192.44.30.122:16621.

That's currently not possible, because the script will be executed for one branch only.

We have it on our todo list, contributions are welcome.

Hi,

a user, we say yang, is registered from different locations, therefor there are multiple contacts in the location table like this:

---

aor : 'yang@domain' Contact: 'sip:10.20.0.100:5060' q: 1.00

aor :'yang@domain' Contact: 'sip:192.44.30.122:16621' q: 0.00

I have configured SER as following:

    if (!lookup("location")) {
            sl_send_reply("404", "Not Found");
            break;
    };

    if (!uri=~"^sip:(.+@)?(10\.20\.).*") {
            forward("192.168.252.2");
            break;
    };

    t_relay();

That says the INVITE should be forwarded to an outbound proxy 192.168.252.2 if the user is not located in our internal network, e.g. 10.20.0.0/24. However, the Request-URI will be overwritten with the highest-q rated contact, in this case with the contact 'sip:10.20.0.100:5060' and the if-block will be skiped. This induces the INVITE to 'sip:192.44.30.122:16621' will be also directly sent but not via our outbound proxy 192.168.252.2, what means the messages will be discarded by the firewall.

Is there any chance to resolve this problem?

Thanks

Yang
