Good work, What was the length of each call.<br><br>-Jai<br>"Buy SIP DID with 20 channels at <a href="http://www.didforsale.com">www.didforsale.com</a>" <br><br><br><div class="gmail_quote">On Wed, Oct 22, 2008 at 2:10 PM, Jim Dalton <span dir="ltr"><<a href="mailto:jim.dalton@transnexus.com">jim.dalton@transnexus.com</a>></span> wrote:<br>

to Back User Agent (B2BUA). Based on the helpful feedback from the mailing<br>
list we improved our test procedures and re-ran a new performance test case<br>
of Asterisk configured as a B2BUA.<br>
<br>
Our test platform hosting Asterisk was a $1000 Dell PowerEdge 840 with a<br>
Quad Core Xeon X3220, 2x4M cache, 2.40 GHz, 1066 MHz FSB and 4 GB RAM.<br>
Redhat V5 was the operating system. The test was configured to simulate a<br>
wholesale VoIP operation with three minute call durations and an average of<br>
two call retries for every completed call. This was an "out of the box"<br>
Asterisk configuration with default settings and no optimizations.<br>
<br>
We found that Asterisk on the test server could handle approximately 1000<br>
simultaneous calls with no codec transalation. This works out to be about a<br>
$1 per port investment for a B2BUA platform.<br>
<br>
When calls were transcoded from G.711 to G.729, the call capacity fell to<br>
320 simultaneous calls. With the added cost of of the G.729 codec royalty<br>
and the lower call capacity, the cost increases to approximately $13.50 per<br>
port<br>
<br>
