Re: [OpenSIPStack] [SF] RTP fault

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Ok this bug seems legitimate.  I have created a ticket for this in 
assembla. 

http://www.assembla.com/spaces/opensbc/tickets/21 .  

If there some more info you could send that might help crush this bug, 
please send them in.  As a backgrounder, the Voice Age G.729 codec 
educational license only allows for one channel to be opened.  This is 
the reason why OPAL statically flag its usage.   Thus, it is very 
possible that this bug only became evident with G.729 but may also be 
true for other codecs as well.  The only diff is other codec might be 
more forgiving than G.729.   More information that would 
confirm/disprove this case, please send them in.

Thanks

Joegen
