[OpenSIPS-Users] opensips + rtpengine

[Callum Guy]

I encountered a similar issue recently, I was using dialog variables
to flag sessions where RTPEngine is engaged so rtpengine_delete only
fired on applicable BYE/CANCEL requests. For reasons I have not yet
understood the dialog variable was not always available so the
sessions were left open and subject to an hours wait for the rtpengine
timeouts. I've tried to improve the logic with AVP's however I'm still
seeing unclosed sessions so am planning just to always fire it off on
a BYE/CANCEL and let RTPEngine drop requests when it is not engaged.
For your script I would recommend that you take the delete function
out of loose routing and implement it whenever you have BYE/CANCEL
requests arriving. I would also highly recommend that you enable the
rtpengine CLI so you are able to control session limits on a running
instance.

Alain, thanks for your anecdotal stats - I've been wondering how far
we'll be able to push an instance of RTPEngine. We have some powerful
24 core machines and are using the packet forwarding module and are
hoping to approach 10000 sessions per instance. If your figures scale
up it sounds like this is very achievable!
