[Serusers] Problem with presence (400 response to subscribe)

[Daniel Machín Vazquez-Illá]

Hello.

I'm having problems with pa module.

I try to SUBSCRIBE to a user's presence and I get a 400 response to this 
subscribe. Ser logs show:

12(10693) handle_subscription() entered
12(10693) parse_headers: flags=1581064
12(10693) parse_hfs(): Error while parsing headers
12(10693) handle_subscription(): Error while parsing message header
12(10693) handle_subscription about to send_reply and return -2

I'm using Ser 9.3 and Windows Messenger 4.7 for testing.

My ser.cfg file looks like this:

[...]
loadmodule "/usr/local/lib/ser/modules/pa.so"
[...]
modparam("usrloc", "use_domain",   1)
modparam("registrar", "use_domain",   1)
[...]
route {
        [...]
        if (method=="SUBSCRIBE") {
                if (!t_newtran()) {
                        log(1, "newtran error\n");
                        sl_reply_error();
                };
                handle_subscription("registrar");
                break;
        };
        [...]

I can post the whole file or the SIP logs if you need them.

Does anyone know why it doesn't work?

Isn't Windows Messenger compatible with pa module?

Lots of thanks.
