SynJ SB67108 Cordless Expansion Handset for the AT&T SynJ SB67138 & SB67158 Small Business Phone System

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.

Great phone, ordered 4 of these with 4 bases. 1 of the bases ended up not working, but all of the handsets worked just fine. Phone has better range than most other cordless phones ive owned. They are also pretty sturdy and hold up in a rough environment.

We were facing either a VOIP system ($3,000 or more) or this system. Some of the reviews are pretty rough but I've been quite happy with this system. We have 6 remote units, one base (utilizing all four lines) and a range extender. Everything was installed in under an hour and we haven't looked back since. The phones look nice, keypad lights up, and we actually think the ringtone sounds nice. Go figure.

Interesting product -- a few great features but a surprising number of features found on our last few phone systems are missing here. However, the phone does work well for calls -- great coverage throughout our house. The batteries seem to last for at least a few days when the phone is left off of the charging cradle. Functionality and clarity are fine. The gripes are relatively minor, all things considered, but it's strange that features one would think would be standard (and which were on our Panasonic system many years ago) are lacking in this system. For example: 1) The handset screen is so bright that, when a call comes in, it can wake anyone sleeping in the room. It's like a 60-watt light bulb. There's no way to dim or shut off that backlight. And speaking of lights, our former Panasonic system had a mast light on the antenna so you could turn off the ringer and still see incoming calls but the light was nowhere near as bright as the screen light on this system's handsets. 2) The base station has no volume control on the speaker so if anyone leaves a message, it's broadcast throughout the house. You can stop the message from being broadcast if you push the mute button each time when the message is being left but you can't set it permanently to mute or turn down the volume (you can adjust the volume when you go back to listen to the message). 3) You can't turn off the ringer for any one of the lines on the handsets. You can turn off all sounds but not, for example, turn off just one line. We use line 4 for the fax so all of the phones in the house ring when a fax comes in. You can change the ringtone for each of the four lines but there are only seven ringtone choices, all of which are more "industrial" that we'd like in our home. And why, in this age of unlimited ringtones, can't you add your own ringtone? 4) You have to program the directory on each handset and the base station. Why not allow people to program their frequently-called numbers in the base station and then "populate" all or some of the handsets automatically? 5) Each handset has a place on the screen that shows that there has been a missed call. If there has been even one missed call, that icon flashes continually on every handset. The only way to turn off that flashing icon is to scroll through all of the caller IDs which have come in, and you have to do that on each handset. They should allow you to turn off that feature. 6) Each handset can have its own mailbox but we only use the mailbox on the base station. However, when checking messages from a handset, it defaults to checking that handset's mailbox first. The system should allow you to program it so that when you go to check messages, you simply can access the base station mailbox directly. 7) The handsets have a jack for a corded headphone but why not add Bluetooth so you can use the same headset as your cellphone? I have many more insights into the areas which could be improved but, the truth is that home phones are disappearing as many people only use cellphones instead of having a landline. Panasonic got out of this business so there's not that much of an incentive for AT&T or the few others still in this market to spend much on the R&D necessary to incorporate upgrades. Would I buy it again? Yes, since this is the only four-line phone with built-in answering system I could find. The price is good and I would have given it five stars but for the strange omissions mentioned above.

We purchased 4 wireless handsets + the SB67158 base. We have 2 land-lines connected to the base and two VOIP lines connected to it (Ooma). We have been using them for 3 months without any problems. What we like is the good voice clarity, exceptional wireless range (about 400ft), durability (dropped wireless handsets many times), and price. What we don't like is related to the SB67158 base. The hold music is one song that sounds like an old black and white horror movie and it is too loud. We want to connect and iPod or computer to the phone for our own hold music, but can not because we are using a headset on the corded base phone and there is only one sound jack. Second downside is the ring tones. There are only about 6 and and they almost all sound the same, so trying to distinguish between the 4 lines is almost impossible. But we just look at the tiny blinking line indicator in the LCD screen to see which line is ringing. Since the wireless handsets are flawless, I give them a 5-star. Overall, I would rate the whole phone system as a 4-star and recommended it to other small businesses. 8-27-15 Update. We have been using this phone system for over two years. I have listed the downsides above. Another downside is the batteries. They only lasted about a year. The replacement batteries I purchased through Amazon are all still working. Another upside is that we purchased the DW Pro2 Wireless Headset System from Sennheiser and we were able to plug it into the wired heatset jack on the base station. It has been working flawlessly for a month. Our secretary is loving it!

Fully Functioning 200%. PTT Intercom Feature not supported on this handset model with my base unit model. Regular intercom and all other features working.

bought a few more of these satellite phones to go with my 4 line base at the office - we abuse the hell out of these phones (dropped on concrete, thrown around the office to each other, slide across the desk, etc). We've had 1 or 2 crack or chip but again we are VERY rough with them! Amazing phones once you get past the price of the main base that you must have!

The phone does what it supposed to . Good and reliable, but the reason i gave it 3 stars the voice could be better since sometimes I can’t hear the customers and one last thing ; it’s overpriced.
