[Users] PA module doesn't work

[Andrea Cacciarru]

Hello, I'm using Openser 1.0.1 with PA module and eyebeam clients. When 
eyebeam receives a presence NOTIFY to a SUBSCRIBE, it responds with a "481 
Call/Transaction Does Not Exist". Why? I've read that PA is unstable, but I 
suspect that this module doesn't work properly.
This is a piece of the cfg file:

loadmodule "mysql.so"
loadmodule "sl.so"
loadmodule "tm.so"
loadmodule "rr.so"
loadmodule "maxfwd.so"
loadmodule "usrloc.so"
loadmodule "registrar.so"
loadmodule "textops.so"
loadmodule "avpops.so"
loadmodule "uri.so"
loadmodule "jabber.so"
loadmodule "pa.so"
loadmodule "auth.so"
loadmodule "xlog.so"
...
modparam("pa","use_db",0)
...

route{
...
if (method=="SUBSCRIBE")
{
if (t_newtran())
{
handle_subscription("registrar");
};
return;
};


if (method=="PUBLISH")
{
if (t_newtran())
{
xlog("L_ERR", ">>>>>>>>>>>>>>> PUBLISH REGISTRAR SIP");
handle_publish("registrar");
};
return;
};
...
}
