I wonder if you can give me a bit of a sanity check on the following design for a shared office. We are somewhat restricted by the buildings cabling, the actual design is a bit larger.
What we require is all IP phones (not Cisco) to be able to talk to each other and Company A's server, Company A's server and PCs to be able to communicate together and Company B's Router and the network behind it to be able to access a shared printer and the internet. Anything without a Cisco part no next to it isn't cisco and must be assumed to be dumb.
I'm not after a detailed howto - I just want to check that in theory this is possible, I'll work bench the equipment if it will work.
