That's good questions Vitalie.  I consider worst case scenario with G711 which  really takes much more than advertised 64KB ,   in fact I feel goes beyond 100KB. I know it make no sense but  sometime I don't' know if other (DB etc..) traffic is killer here.  We might move to gig bandwidth environment soon so bandwidth shouldn't' be problem. 

On my current server (Quad Core 2376 2.3GHz , 4GM RAM) ,  I  start getting garbled voice ( all kind of delays ) on 200 channels usage and it's all pcmu.

Which codec is used?

Did you get a chance to measure the total bandwidth consumed when all 1000 channels are active?

Are there any minor or major voice quality problem?

Thanks
