Summary:                    [patch] endless wait for RTP when both legs have
a=direction:passive in SDP
Description: 
A Dialogic machine that I'm peering with has the ability to go into passive
mode for RTP traffic (adding a=direction:passive to the SDP body). I
haven't figured out why/when it does so, but when it does -- and it always
does in my current setup -- everyone ends up waiting for data and no RTP
stream gets set up.

---------------------------------------------------------------------- 
And as to where the a=direction:passive came from. "Comedia mode" was set
to Passive (
http://excelsupport.dialogic.com/imgpubs/webhelp/ipbearerentry.htm ).

Disabling this feature resolves the issue I was having. That means that
the issue is now only a theoretical one for me: yes, there is something
that could be fixed, and no, there will probably be very few people needing
it.

Walter
