[Asterisk-Users] hardware and network requirements

Hi,
The usual bottleneck is cpu.

Unknown number of concurrent calls (with prompts and hold-music).


Can you provide an estimate on the maximum number of calls 
in queue ?


The second major question is how are you going to recieve 
the calls ? VoIP (g.729, g.711, ???) PRI card on server ?


Question three: I assume you're going to run voip for the 
agents. What codec are you going to use on the agent side ?
(g.729, g.711, gsm)


The real question is how much transcoding are you going 
to do ? Because that's where your clock-cycles are going
to be spent.

Most likely. It'll do 40-50 concurrent 711 to 729 transcodings.
