How much CPU and RAM a single dahdi channels consume

Hi Bros,

I have one query regarding DAHDI Channels, that how much CPU and RAM a single dahdi channels consumes?? and how we dimension a server machine if we want 240 concurrent calls per server.

Highly thankfull in advance.thanks

hello:
i think quad core CPU and 4-8G RAM should be sufficient for 240 calls.

Depends on what you’re doing with those channels. Wrapping them up into G711 SIP calls and passing them off? No problem.

Transcoding them down into G729 and doing recording? You’re going to be thrashing your machine.
