Re: [Serusers] how can I look up the username in the location table?

Thanks for your reply. I wasn't sure about the URI and the To/From thing. I looked at the packet and when you register, the username is in both To and From. I guess I mistook the URI for that or something. Thanks for your clarification on that.

I'm trying to limit the number of people using each username to a single person at a time. I read the mailing list of people trying to do this before me, and everyone, including Jiri, didn't understand why someone would want this.

Well, I have a bunch inbound agents logging into my SER proxy with softphones, receiving calls from an AudioCodes Mediant 2000 (T1 <-> SIP) that is getting calls from an Avaya PBX. These inbound calls have to go to whoever is logged in as that agent name, and only to them. We can't have multiple people logged into the same name, because each name corresponds to a certain phone number on the Avaya PBX. I hope this makes sense. It's not really a normal SIP application in this sense, which is why I need to remove the ability of a normal SIP application.

I'm using the latest stable release of SER, and can't be putting anything less into production. I know that the next release has the max_contacts option, but until it goes stable, I don't have a green light to use it.

I'll look into the avpops module, as I haven't really heard of it until now.

Hi!

Lookup takes the request URI und looks up the location table. In REGISTER messages, the address-of-record is in the To: header. Therefore, lookup() will fail always.

Maybe you can overcome this by copying the To: URI into an AVP and then copying this AVP into the request URI. (avpops module).

Btw: Why do you need this feature?

I want to look up the username in the location table during the method==register if block.

The reason I wish to do this is to see if there is another location currently registered in the database for this particular username. How can I do this? Do I have to use exec_msg() or exec_dset(), or does lookup() work?

I've tried lookup("location") but it failed to work, it seems.

Can anyone help me out? Here is the block of code that I'm trying to use:

    if (method=="REGISTER") {
            if (!search("^Expires: 0")) {
                    if (lookup("location")) {
                            sl_send_reply("200","Another registration.");
                    } else {
                            sl_send_reply("200", "First registration.");
                    }
            } else {
                    sl_send_reply("200", "Unregistration.");
            }
            save_noreply("location");
            break;
    }

Note that it is sending the proper replies for "First registrations" and "Unregistrations," but not for "Another registrations."

Thanks in advance,

Dana
