If the suggestions that have already been posted don't work, then I'd
suggest running ethereal (or whatever your favorite packet capture utility
happens to be), and using the resulting trace to see what is happening on
the wire. You should be able to see a hangup if the issue is coming from
asterisk, or if the issue is coming from his phone, etc.

If you do this, do a capture filter on his phone's mac address, and post
(or send me directly) the last hundred or so packets from the trace.
