<p class="MsoNormal"><span style="color:#1f497d">Hi guys,<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d">The voice requirements that were used were pretty simple-sounding, something like:<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d"><u></u> <u></u></span></p>
<p class="m_2273271513045117208MsoListParagraph"><u></u><span style="color:#1f497d"><span>1.<span style="font:7.0pt "Times New Roman"">
</span></span></span><u></u><span style="color:#1f497d">Move a call multiple times between multiple links in response to multiple link failures without losing audio quality or signaling<u></u><u></u></span></p>
<p class="m_2273271513045117208MsoListParagraph"><u></u><span style="color:#1f497d"><span>2.<span style="font:7.0pt "Times New Roman"">
</span></span></span><u></u><span style="color:#1f497d">Conceal up to 5% packet loss from SIP and RTP on a single link<u></u><u></u></span></p>
<p class="m_2273271513045117208MsoListParagraph"><u></u><span style="color:#1f497d"><span>3.<span style="font:7.0pt "Times New Roman"">
</span></span></span><u></u><span style="color:#1f497d">Simultaneously meet requirements 1 and 2 for any combination of links<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d">The requirements sound simple, but you folks know how hard it would be to implement something like this. We had other requirements to deal with our core application and data-center oddities, but those voice
ones can pretty much stand alone.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d">In retrospect, we might have phrased #2 in terms of “MOS per unit loss”. Something like “Calculated MOS score on a g.711 call can drop no more than 0.1 with 5% packet loss” would have been more measureable than
a subjective ‘can you hear me now’ kind of opinion.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d">We wound up going with VeloCloud.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d">Best advice is to shoot for the moon on your requirements, and test the living daylights out of it.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d">Staying away from all the NDA-breaking geeky stuff, here are warning signs to keep an eye out for:<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d"><u></u> <u></u></span></p>
<p class="m_2273271513045117208MsoListParagraph"><u></u><span style="color:#1f497d"><span>1.<span style="font:7.0pt "Times New Roman"">
</span></span></span><u></u><span style="color:#1f497d">Vendors that don’t let you run your own pilot. If they insist in being right there with you, their stuff isn’t ready for production.<u></u><u></u></span></p>
<p class="m_2273271513045117208MsoListParagraph"><u></u><span style="color:#1f497d"><span>2.<span style="font:7.0pt "Times New Roman"">
</span></span></span><u></u><span style="color:#1f497d">Over-reliance on fancypants graphs. Amazing graphs are great and all, but not even close to being as important as actually fixing problems.<u></u><u></u></span></p>
<p class="m_2273271513045117208MsoListParagraph"><u></u><span style="color:#1f497d"><span>3.<span style="font:7.0pt "Times New Roman"">
</span></span></span><u></u><span style="color:#1f497d">Scoping assertions. One vendor asserts that “an SDWAN can only be as good as the underlay network” because they simply can’t do error CORRECTION. If you buy off on their assertion, you’re doomed.<u></u><u></u></span></p>
<p class="m_2273271513045117208MsoListParagraph"><u></u><span style="color:#1f497d"><span>4.<span style="font:7.0pt "Times New Roman"">
</span></span></span><u></u><span style="color:#1f497d">Hiding behind “best effort”. Can’t tell you how many times we heard “oh, that feature is just best-effort, it might not work all the time” when we pressed them. For EVERY feature that is important,
be sure that you nail them down what actually works 100% of the time and what they implement as some kind of throw-away ‘best-effort’ slideware feature.

<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Hi,<u></u><u></u></p>
<p class="MsoNormal">Is anyone else using SDWAN for VOIP?<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">We can move a call between links and impose 10% packet loss and the users pretty much don’t notice anything. No loss of call control or mid-call signaling, barely detectable impact on audio quality.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">This is pretty much the only way we’ve found to deliver the quality that our (very demanding) customers require using a ‘bring your own bandwidth’ model.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">It has been such a game-changer for us that I’m being sent to SIPNOC to give a talk about it.
<u></u><u></u></p>
