Re: [Ccrtp-devel] combining a sipstack with ccrtp

[David Sugar]

I recently (this past weekend) did a lot of work with oSIP and ccRTP in 
Bayonne (look for a new and very sip friendly release of Bayonne when I 
get back to US next week).  In Bayonne we can actually do a session 
cleanup management thread like in Bayonne H.323.  Autodestruct is 
certainly possible, but it cannot be mixed with external destruction 
since the thread must be started from detach().  Perhaps if the session 
thread detects it was started by detach() rather than through start() it 
could then do a timer and do it's own autodestruct.  At least this is 
one idea...
