[Users] does openser support QoS ?

The more obvious question is:

How does it know there is no more bandwidth available? As a signalling proxy, surely it has no visibility of the RTP usages or requirements.

I guess if it counted all the complete INVITE-> OK dialogues and the SDP codec used it could estimate usage? But the RTP/media path could be different in each case of these so again the same question as above......

Hi Yanlin,

if the bandwith is exceeded, no new INVITEs will get to the server and will 
timeout. :-) The "pike" module does some kind of DOS protection, but this is 
also no real QoS. 

There was a discussion two weeks ago about this topic on devel (the topic 
was "rand function in config file"), Klaus suggested some kind of bandwith 
management module there. But at the moment such a module don't exist in
