I'm using nua_subscribe to send a subscription out. Apparently, sofia
then helpfully immediately unsubscribes me right after the 200 OK comes
in. I want to stay subscribed so that I keep seeing NOTIFY messages and
having r_notify events generated, rather than just getting one NOTIFY
that comes in right after the unsubscribe (and which sofia then sends a
"481 Call Does Not Exist" to).
I'm relatively new to sofia and nua, so I'm sure there's something I
need to do beyond keeping a reference to the nua_handle (which I've
tried) to keep it alive?
Trace is below.
