Ok, I've had some back and forth with the linphone developers and they 
contend that although the sequence number on the 2nd and 3rd SUBSCRIBE 
messages start a new sequence this is legal as it is a new conversation 
-- the "tag=" on the From has changed.

Are they right?  (Notice that the tag= from asterisk also changes).
