What's you mix of calls going SIP/IAXand to PSTN?<br><br>We've done some benchmark experiments on a 3GHz HT box with 1GB of ram, mirrored traditional IDE disks. The box has a Digium quad-PRI, a TDM40B, a TDM22B and a Sirrix quad-BRI board in it. This box can run 120 active calls over 4 PRI spans. Its running
<br>MusicOnHold into 60 of the channels, playing various GSM prompts into the other 60. The "user" cpu usage is about 25%, the "system" cpu about 25% also. We can add to that 5000 registered SIP peers and 5000 registered IAX2 peers - total of about 100 registration refreshes per second. That adds about 40% more user CPU and pretty much fills up CPU. Audio quality is still perfectly fine, and PRI slips few and far between. Load average for the whole mix sits between 5 and 10. About 550Kb/s out and 400Kb/s out on the ethernet for the registration traffic.

<p>Hi,</p>
<p>we are currently considering different options for rolling out a large scale IP PBX to handle around 3,000 + concurrent calls.</p>
<p>Can this be done with Asterisk? Has it been done before?</p>
<p>I really would like an input on this.</p>
<p>Thanks!</p>
