<p class="MsoNormal"><span style="color:#1F497D">Like any metric, MOS is up to you to interpret.</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">You will need to determine if at a certain call threshold you can predictably see your MOS drop. >From there you will need to see if you can relate this to CPU, RAM, network saturation etc. For example, if a particular
trunk fills up and you start using a different provider at a certain number of calls, this could be normal for you based on why that provider is used as an overflow and isn’t necessarily unexpected behaviour.</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">As such please bear in mind that MOS from VoIP Monitor is not a definitive metric of something out of the ordinary. It is very helpful to help indicate potential issues but is not by itself any indication that
something is not working as expected. For example telling your carrier that VoIP Monitor scored a few of their calls poorly probably won’t get you much on its own.</span></p>

<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We’re considering using VoIP Monitor to analyze the call quality of our Asterisk switch.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Here is a snip from the last 8 days. I notice that the 99% MOS drops when we seem to have more calls going on. Should the 99% MOS be pretty flat throughout the day or is this graph indicating that I have a problem that I need to look
into? (I’m not having any complaints. Just trying to be pro-active.)</p>

<p class="MsoNormal">As always, thank for your feedback.</p>
