I'm trying to setup an extremely basic PRESENCE/BLF environment.
However, when I call handle_subscribe(), the message gets sent to $si:5060, *not* $si:$sp
Any ideas?  Should I be doing something with nat_traversal.co (don't see what, but worth asking...)

The relevant portion of kamailio.cfg is

   if (!t_newtran()) {
        sl_reply_error();
        return(-1);
    };

    if (is_method("SUBSCRIBE")) {
        handle_subscribe();
        t_release();
    };


Cheers, and thanx for any help
