[asterisk-users] 400 calls at g711 how much cpu power

[Erick Perez]

We are planning to run an outbound only campaign. A 20-second voice message
will be played to callers and our dialer on machine1 will send to
machine2-asterisk (1.4) instructions to dial 400 calls, play the message and
hang up. This will be done for about 1 million phones.

The asterisk box will communicate via SIP to a voice carrier. the voice
carrier will then place the calls on pstn. The codec will be g711. So we
will never do any transcoding.

I have been calculating the CPU power required to do the calls and in
previous posting the usual calculation is about 40MHZ per leg when no
transcoding is involved.
So if we use the 40MHZ rule, we are talking about 40*400=16000MHZ or 1.6Ghz.

Comments?
