It appears monowall has QOS that would benefit a system with VOIP. Can someone please confirm this.
yes
Does it have SSH capability, if not a suitable alternative?
No, it's not necessary though. Unlike IPCop, you can actually do everything in the webGUI.
If I had a box setup up with 1 input and 8 ouput jacks could I use the Monowall as a router/switch as well?
Not as a switch since you can't bridge multiple interfaces together, but as a router, yes. Generally because of the overhead involved in filtering with any software or device, you don't want to do something like this unless you use some beefy hardware.
Does it allow plugin modules? Like Open VPN?
no
Does Monowall use the annoying zones like IPCop. Don't get me wrong... the zone concept is a great idea for security, but for what we need, imagine a room of developers, its overkill. Everything that I have seen so far says no.
I'm not exceptionally familiar with IPCop - what do you mean by zones?
