Hey, my name is Tyler Smith, I'm VP of Sales Engineering. This is Nick Schroeder, he's our UC engineers and we wanted to demonstrate kind of in a live format SD-WAN experience. So what we've got going on is we've got two phones with active phone calls that are hosted VoIP phone calls, we've got three internet connections that are being kind of bonded together managed by an SD-WAN platform.

So there's 100 Meg fiber connection, there's a coax connection, there's a 4G backup connection and so we're gonna demonstrate what that looks like when it when outage occurs and what that happens from a voice quality perspective. So I'm gonna hand it over to Nick. Awesome thanks Tyler, so like you said we have our two phones set up here. They're on active phone calls to the hosted UC providers and up here you can see our three different connections. So over here we have Comcast cable, then we have central Utah telephone, which is Center comm, that's our fiber 100 Meg fiber and then we have our Verizon Wireless, which is the LTE connection. So down here I'm gonna go ahead and start the music in here.

We are using music because it makes it a lot easier to hear the transition when one of the land providers goes down. You can kind of hear that there's not, you know, there's not very not even a blip so that being said let's come walk over here. Alright, so up there you can see that central Telecom is the connection that's using right now which is what we would expect because it's the hundred make fiber so it's the SD-WAN box is saying “yeah I think this is the best connection for these phone calls right now”. So I'm gonna go ahead and unplug the central com connection, okay you guys just heard a blip for just one second, this connections gonna go down and you'll see in here. Okay there it is, so central comas down now and you can see that the SD LAN box is gonna start to send those voice calls over one of the different connections so in this case it shows the Verizon Wireless connection as you can see there it's going to start pumping data through there.

So I'm now going to move move it again over to the Comcast connection by taking down the Verizon connection. So we're gonna go ahead pull the Verizon connection. Okay so you just heard a blip again. Verizon just went down and now on the screen you can see that the Comcast is starting to pick up there, so when we think about what just happened right we had an active phone call two active phone calls that are on a host of web provider. We didn't drop the phone call but we had a small blip and the audio and so comparing that to a traditional format, where I had maybe I have a load balancing firewall or I have redundancy built in in my network what we would have experienced is these phones would have gone down. The phone call would have dropped.

The phones were to be registered and we would have had a very quick transition from one provider to the other but the end of the day we were kind of restarting our environment but what SD-WAN is doing because it's priority traffic it's making that transition occur completely seamless. So from an end-users perspective if they were on a phone call with a conference you know on a conference call that's an important phone call of any kind they wouldn't have even skipped a beat they really wouldn't even perceived that issue. And the outage right that would have caused the loss productivity and the challenge of them having to read register and all the other things that come back around. We talked about that SD-WAN smooth all that out and had that transition, kind of basically us on a flawless basis. So, just a brief example of one aspect of what SD-WAN can bring to the table and we really appreciate you guys taking a look at this video.
