Review of this phone is missing 2 important points: - one that the transfer is not 100% 5.8 MHz, a combination of 5.8/2.4 MHz - very important if you care about WiFi problems - compared to AT & T 5840 on prices, the two that Uniden 5, 8 MHz 5.8 MHz true, and although it with 2 handsets (I can not even more) is, you can not use both phones at once at the conference - it's one or the other. This is a big disadvantage for Uniden. I have AT & T 5830 - AT & T 5840 compare price model without the answering machine, but it's a nice thing to say numbers - it can tell you are set to (synthetic voice) who's calling - to subscribers of Caller ID, or you can write a message such as "Mama", etc., and the phone will play the voice recording when the number of calls (caller ID subscription required). I can not evaluate AT & T customer, I have not used it. Chisels do not buy AT & T 5840 m at the best price, which was said in the review, the range of the headset where your ear is lit neon blue when the phone set to ring. Each tube has a separate directories, the manual program numbers in memory have, but it's not too bad, because different people may want to store a different number of contacts in each set. Option to sync would NI AT & T 5840 Price CE. However, it seems the magazine ID (new challenges) for all mobile phones, never mind. Handsets can be named, or they are simply registered in the database as you add them: 1 handset, 2, 3, etc. In addition, each handset speakerphone and can page other handsets or the base station. Overall I am very pleased wit AT & T 5840 for best price hours after purchase. I want to buy AT & T 5840 for best price synchronization method of memory and function, since my old Uniden 900 MHz was: Call timer, I tell you how long your call after you hang up. Very useful for the future of all mobile phones there.
