This EnGenius system consists of a base unit, one handset, a NiMH battery pack with 80-minute fast charger, and two AC/DC adapters. Each base unit can support up to nine handsets (sold separately), and each handset can be registered with up to four base units. The system is expandable to up to four lines with four base units and 36 handsets. Network features include hold, call transfer, call manager, and a programmable ring feature that allows you to select each handset to ring with every incoming call or only ring for transferred/intercom calls.
The EnGenius system features full-duplex capability that allows handsets to communicate with each other as two-way radios. A long antenna is included with each handset to maximize range in open areas. Independent of the base, full-duplex capability lets you talk and listen at the same time with no group chatter and with the convenience and comfort of a phone handset. Digital spread spectrum technology means the phone hops frequencies more than 200 times per second, ensuring privacy.
Other phone features include call waiting and caller ID compatibility, 30 presets for speed dialing, selectable three-level ringer volume, and six-level voice volume. The handset operates on a NiMH rechargeable battery for three hours of talk time and 40 hours of standby time. A trickle charger is included, and you can even charge the battery while a caller is on hold at the base unit.
This phone comes with a one-year warranty.
Well, this phone works admirably - it has more than enough range for a large property with no fade out. The handsets are tough and feel solid (they are really meant for factory or warehouse use). Battery life hasn't been an issue for us at all - in a home you usually keep the handsets in a charging cradle when not in use anyways. Voice quality is as good as the Siemens was. And the fact that it works at 900 Mhz is a bonus since it won't interfere with my wireless Ethernet (802.11) network.
This is an update since I've had these phones for about 6 months now: They aren't perfect. When you put the phone into the cradle to recharge, you have to put it in carefully otherwise it'll look OK, but won't be recharging. Also the recharging contacts are fragile compared to other phones and in fact I have to toss out one of my SN-920's 'cause the contacts got damaged. And the microphone on another SN-920 died. Also, the phones aren't comfortable against your ear.
My ideal phone would have the SN-920's distance with better ergonomics and better recharge contacts. Unfortunately, I don't know of such a phone.
