## Description

A contemporary workhorse suited for any small business, the AT&T SB67158 corded/cordless

Review: Works Great! - I bought this to install a wireless phone system for a VERY large concrete house. I bought two of them and can service the whole house. I have the Base station on one end then a repeater in the middle of the house and a repeater at the opposite end of the base. Programming was a breeze. Beware if you want to re-assign the number assignments of the Handsets you will have to re-connect the Extenders as well. Only very minor negative is the cord cabling in the bottom presumes that it will be wall mounted (comes out the front), so when I placed it on a desk it is backwards. Could have easily been designed to have cord come out back/top. Love the whole system. Versatility and call quality are the two best attributes.
Review: GREAT for small offices; would probably work perfectly in a good-sized home as well. - We use these for work and bought some additional handsets when we expanded to a larger office suite -- we can even go across the hall to the community breakroom and there is NO static whatsoever! Pairing these to the base unit takes about 30 seconds, and the whole system made our move to our new space practically effortless -- we had very little work to do to hookup our phones since only the base unit actually required a phone jack. I usually use this unit for several days at a time before placing back on the base to charge. I don't use the phone for long periods of time, but can go pretty much all week using less than 1 charge and simply put it back on the base for the weekend. FYI - you can also call between these handsets like extensions using the INT button, if your coworkers keep the same handsets all the time.

### ⭐⭐⭐⭐⭐ Works Great!

### ⭐⭐⭐⭐⭐ I'm so happy I bought it
*by D***R on April 3, 2014*

We had for 10 years a Panasonic phone similar. A base and 4 extensions, we have 3 phone lines. It finally died. We bought an RCA phone from another vendor, a base and 4 extensions. You won't believe, if ONE person picked up a phone call NO ONE could use any other liens or phones. Stupid. So I returned it and looked here on Amazon. There are some reviews here that the portable handsets didn't last long and made me wary to buy it. But we went to every office supply store and computer store in Atlanta and no one sells a phone that will work with 3 or more liens. So we took our chances on the AT&T setup. We are very happy. We work from home, a 3 store condo With the double antenna the other wireless handset works great 2 more floors down. Setup was a breeze. Registering each hand set to the base took 45 seconds per phone. 2 people can be on the same line with someone else, that wasn't possible with our old Panasonic. Intercom is easy, everything. We did not setup voice mail, our phone company supplies it for us. The only CON (small thing) is a feature. if you pick up line 1 and think "I should really be on line 2" and you just push line 2, you expect line one to hang up. It doesn't, it puts line 1 on hold. So 2 lines are "in use" easy to learn. if you pick up line 1 and want instead to make a call on line 2, hang up the phone and push "2" and go from there. The reasoning is this. if you're on line one talking and someone calls on line 2 you don't have to click HOLD. Pushing line 2 automatically places line 1 on hold. So we are hoping the phones last well, they seem solid enough. We highly recommend this phone. By the way for the base and 4 handsets we spent about $575 and other places on the internet had "similar" at&t phones for 50% to double that. Thanks Amazon. we are prime members. We ORDERED this phone system on SATURDAY and Amazon has carriers who pick up on Saturday and Sunday at their facility. We got the phone on Monday. Phew. Great service.
