Re: [OpenSIPStack] [SF] RTP fault

[Whit T. <de...@wh...>]

I have also been able to replicate this issue. So far I've only seen it
happen using G.729. The first call seems to go through, but every subsequent
call attempt fails. I am going to try recompiling an older snapshot of the
CVS source I have. 

H.Kropf - Have you found out anything new on this issue?

Hi,

Thanks for the logs.  They were very helpful.  It is evident that the 
previous call did not destroy the codec properly.  I will try to 
replicate this on my system.  Ilian is currently on leave so it might 
take a while for him to catch this thread.  I have created a ticket for 
this:  http://www.assembla.com/spaces/opensbc/tickets/20
