| I spoke to Nextiva and they say that all their functionality is cloud based so that as long as each phone has access to the internet, they don't need to be on the same VLAN.|
Ok, let me explain a couple of things to you since it's obvious you don't quite understand.
First, what I said above about VLAN's and their appropriate setup applies only to your internal network (LAN).
Second, the "cloud" (don't you just love buzz words!) is external to your network. As in, not a part of your LAN. What I wrote above is internal and designed to help you get packets, be they data or VoIP, back and forth from your internal network, to
a) other parts of your LAN
b) to the internet (external)
Once the data leaves your network (LAN) and heads out to the "cloud" you are now on somebody elses network and your VLAN tags are gone.
What the person you spoke with at Nextiva has no clue about is your internal network and was speaking solely about what happens once the VoIP leaves your network and enters "the cloud"
Third, the person you spoke with is likely a helpdesk analyst and as such, has little or no formal training on computers, has little or no experience working in industry and probably doesn't know the difference between a VLAN and a VPN.
If you're going to use VLAN's internally in your network, and from the sounds of your situation, this is the best solution for you, then you have to have a VLAN for the VoIP or the VoIP phones will not work and neither will any computers plugged into them.............period, end of story. Without a VLAN for the VoIP in a VLAN environment, the VoIP data goes nowhere, much less outside your LAN and out to "the cloud"
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
