[Serusers] SUBSCRIBE -> BAD REQEST (Instant Communication Application + PA Module) - sr-users

23 May 2005


      Hello Everybody
I am trying to create Instant Communication Application based on MS RTC 1.2
library. I am also using SER 0.8.14 as a SIP server. Voice communication
works perfect, messages works perfect but I have a big problem with sending
user's status. 
When I tray to send SUBSCRIBE message I get BAD REQEST response.
T 10.1.1.62:3749 -> 10.1.3.10:5060 [AP]

I configured the presence module, added the lines to ser.cfg
if (method=="SUBSCRIBE")
                {
                        log(1, "Subscribe\n");
                        if (t_newtran())
                       {
                                log(1, "Registrar\n");
                                handle_subscription("registrar");
                      };
                        break;
};
But it still doesn't work. 
Has anyone faced a similar problem ? Why it doesn't work ? Is the PA module
compatible with MS RTC. Why this masseges are in bad format.
Any ideas are very welcome.
