Aha - this explained a lot of things.

I think I might have figured that out...  sure took me long enough.

Actually,  it would drop in about a minute... pretty consistantly,  but 
it was
because I wasn't issuing a keep alive to the SIP server while the RTP
session was in process.  I thought that all I needed was to send the
RTP keepAlive to keep the connection open to the remote client.

Then I realized that the SIP server wasn't getting IT's keep alive
so it eventually timed out,  and sent a "bye" to the remote client
killing the connection.
