<p class="MsoNormal">Sure, you could fence them off if creating an isolated or appropriately gapped network is in your wheelhouse. Since the devices are usually used with pass through, they’re potentially exposed to some issues regardless of how well you try
and secure the address space of the phones.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In my case I ran into issues with 79x1 series devices exposed to either some type of traffic or too high of a volume, which caused the phones to become unusable. It is not fixed and never will be as there is no longer support. If that were
to happen to someone else, it becomes I think a problem to try and patch around phones where cabling isn’t present, replace devices rapidly, etc.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But, yes absolutely you could bolt a 7940 to the wall on a private network by itself with the PC Port off, only allowed to speak to the UCM and maybe relayed to gateways or other devices, and then it could be okay.<o:p></o:p></p>

<p class="MsoNormal">I know the security argument is valid in some respects. But, if I have an insecure IoT device on the network, like a temperature control system, I don't have the option of replacing it. So, I ring fence it. I isolate it so that it can't
be exploited, etc. Maybe I'm missing something, but isn't that what we can do to workaround the security issues?<o:p></o:p></p>
