I'm about to do an upgrade. We have 6 branch offices that have AVAYA phones hanging off Cisco 1812 routers VPN'd back to the central site. The 1800's have an 8 port switch built in with no POE so currently my phone all have POE injectors. Ideally I'd like to find something that is small yet reliable. Most of the sites don't have racks - devices are wall mounted. So a small soho switch would be ideal. I was looking at the Avaya 3510 ERS simply because of size and solid state.
Any suggestions would be greatly appreciated.
