I just finished installing a UC320 at my company, and I have to say we are quite pleased with its operation so far. We were upgrading from a 20 year old PBX that had all the functionality of cans and string. We've had the UC320 up and running for about a month now with few problems. We are using it in combination with a SPA 8800 gateway for our 8 FXO lines and also to power analog extensions in our production area. We have 16 SPA303 in the offices. The only issue that I have had was getting the unit setup as a network appliance. We are currently running it with the WAN port unplugged. The only issue I had was setting the system time, but that was easily fixed via the phone interface. Once I got the system up and running and some initial call flow bugs worked out, it is very easy to maintain. The AA works great we have one primary menu that then feeds into three department submenus. That said, not many SMBs have their own dedicated IT guy to fix little hiccups. Something that may take me a few seconds to fix may translate into hours when an SMB has to call an IT company for support. Our old PBX may have lacked some of the functionality of newer systems, but the thing was a tank. One feature that is missing from virtually every sytem I looked at prior to buying the UC320 is the ability to do a hook flash. That would be a much more effient way to transfer calls to outside lines.
