I've got a single Snom 320 in front of me, and one of my former clients had a mix of Snom 320 and 300. Had one Snom 320 "die" within a month. Would just boot and boot and boot, never getting anywhere. RMA'd back to the vendor I purchased from and got a replacement. Then I had two handsets (yes the speaker/mic part) die. Snom wouldn't help me on that, so I ended up finding a vendor who sold just the handsets for $25.00.

The web admin page has a ton of options, not very well documented. I don't like the shape of the handset or the texture (easy to drop off shoulder). Speakerphone is kind of weird. The first second or two of sound gets cut off before the speaker starts working.

I haven't figured out how to get MWI working yet. I think I'd go with another brand to be honest.
