After two days of using these little phones around the house and office I’m feeling pretty good about them. They’re very small, which is potentially less than ideal, but so far it hasn’t been a problem. The batteries are Lithium-Ion and the talk time seems very good.
I used one with an old Panasonic headset for a series of conference calls today. I probably spent four hours on the line. The call quality was excellent. Volume on both the phone and the headset was good, which had been a problem on wifi phones I had tried previously.
The speaker phone feature seems a little less than ideal. Not loud enough for many situations and the mic is not that sensitive. Happily, I don’t really need it anyway.
The belt clip has a thoughtful shape that really clips hard onto a belt or pocket and won’t come off accidentally if you bend over.
Thus far I’ve been making & taking calls using Junction Networks OnSIP hosted PBX. I’ll eventually have them working with my Asterisk server as well. They support 8 separate registrations that can be mapped to one or multiple handsets.
The phones are very intuitive, mostly behaving as you’d expect a common cell phone. Intercom between the handsets is easy enough.
The manual is good but basic. More detailed documentation is to be provided by way of a wiki but that has yet to be undertaken.
I’m traveling to England for a week starting Saturday. My wife will be using one of the M3s to reach me while I’m away.
More later, including pictures, shots of menus, etc. Expect a detailed review in about three weeks.
