we are try setting SER as presence server, we add:
 
loadmodule "/usr/local/lib/ser/modules/pa.so"
 
if (method=="SUBSCRIBE") {
                        handle_subscription("registrar");
                        break;
                };
to ser.cfg.
 
It dosen't work. All "SUBSCRIBE" message, has not been responsed!
 
Anybody can help to teach how to use PA ?
 
Thanks
