Minimal hardware request for Asterisk


I’m searching over the internet for minimal hardware request for Asterisk server, but I can’t find it.

So, is this configuration ok (for 30 SIP accounts):
Processor: Intel Pentium 3 - 1.0 GHz
RAM: 512 MB
HDD: 40 GB

the processor is a little slow but you have more than enough ram and HD space. As long as you are not doing a lot of transcoding and call recording you should be fine.

So, how fast processor you suggest?

You’ll find that no matter how much you research, you won’t find a simple answer to this. There is no basic formula such as “To support X phones/calls, you need Y hardware.” What you have will probably work well enough, but be prepared to purchase new equipment for a production system. I’ve found that Asterisk is not demanding insofar as raw power but is finicky about quality hardware. For a production system, use only the best components–but not necessarily the fastest. In short, don’t skimp on an off-brand, cheapo motherboard. Supermicro boards, for example, have a great reputation with Asterisk. The more I talk to Asterisk professionals, the more I see that they are, by necessity, connoisseurs of PC components.

Hi, i have a question too.

I want to buy a D410P 4xE1 ISDN PRA CARD and i don’t know what kind of machine i need to start whit this.

I have:
Dell optiplex 740 with athlon 64 3800+ (2gHz)
180 GB HDD

Is this enough ?

I want to create a record-system.
People1 call to people2. People2 call to asterisk and starting a conference (p1, p2, asterisk). Asterisk must record this conference. Max 120 channels (4 ISDN x 30channels) in the same time on one machine.

That should be fine for recording a conference of a few people. However, I don’t have a lot of experience with conferences, so please take this anecdotally. I do know that large conferences take a lot of CPU, especially if Asterisk must transcode many different audio formats concurrently. Conferencing is often the “killer app” in a PBX system.

Keep in mind that what determines Asterisk’s hardware requirements is not the number of phones/extensions that need to be supported but the number of concurrent calls that need to be supported.

hi, about the motherboard, we are planing the buy a server with a SUPERMICRO X7DVL-E 771, any feedback about that model, and by the way we are plannign to use the AEX2400 card…

Thanks a lot
