</div>For reference it would have been nice to put the specs in the mail rather<br>
than asking people to look for it.<br>
<br>
For reference: It is a Intel Atom D510 based board.<br>
<br>
The answer: It depends....<br>
<br>
Performance is based on many things. Two common parameters are: Concurrent<br>
calls (how many is speaking now) and Calls Per Second (CPS - How many<br>
calls is setup pr. second).<br>
<br>
If you actaully mean 100 phones then the number of concurrent calls is<br>
most probably much much lower.<br>
<br>
The next important question you need to ask is whether you want to do<br>
transcoding. Transcoding is recoding from one codec to another and is CPU<br>
intensive. If you are mainly using this as a local PBX with a few SIP<br>
trunks you will probably not need to do a lot of transcoding. But again:<br>
It depends.<br>
<br>
You can find a few real world results here:<br>
<a href="https://wiki.freeswitch.org/wiki/Real-world_results" target="_blank">https://wiki.freeswitch.org/wiki/Real-world_results</a><br>
<br>
Of note is an old Atom N270 which is said to handle 10 concurrent calls<br>
with virtually no CPU usage.<br>
<br>
And a quick Google gives:<br>

<br>
Those tests are with transcoding on Atom N2600 and N570:<br>
- around 10 concurrent calls with 20-25% CPU usage<br>
- maxes out around 20 concurrent calls<br>
- Guestimates that the platform should be able to handle around 40-50<br>
concurrent calls with no transcoding.<br>
<br>
Is the board then good enough for you? Maybe.<br>
<br>
My guess: Most probably yes - if we are talking 100 handsets and not 100<br>
concurrent calls. If concurrent calls you might need something beefier...<br>
