Re: How to get connections state of a Device .....

If you have a handle on the call, then the second part of my example should work. To get a
handle on a call, you can register a CallListener on an Address so that when a Call is
created you will be notified and be able to look at the Connection information.

You can also ask an Address for its Connections and then trace these back to the Calls and
the other Connections on the Calls to get all the Connection states.

Finally, you can ask a Provider for all the Calls in its domain and then look through them
for a Call with a Connection associated with your Address. Note, however, that
Provider.getCalls() may throw a ResourceUnavailableException if too many Calls are present
to return.
