Sangomas406 VoIP Phone with POE (or AC Adapter Sold Separately)

In short, this is a pretty good phone. We have over a thousand users, and we've tried just about every brand of IP phone. One of our users had 3 of these phones prior to joining our group, so they didn't want to buy new ones.It is interesting that this phone is suspisiously identical in shape to one of the Chinese brand phones we have. So it isn't too hard to figure out who actually makes this thing. No big deal, since the phones work fine with our voiSip voip service and cloud phone system. It has the same features as the Chinese version, and was easy to setup.My only knock is that this version costs quite a bit more, for essentially the same thing.Also, I wish these phones would come with power adapters. PoE is just a bit too flakey. A lot of people assume you can just add a PoE switch, and you're done. But the problem is, many offices have really terrible network cables in the walls, that are not suitable for PoE. So be careful of that. If your phones seem to reboot randomly, it may not be the phone, but the PoE. Trying using the separate power adapter, and it may solve the problems.
