Great Little Device!
I will start out this review by saying I do still have landline telephone service at my house. But recently I took possession of an old landline telephone that belonged to a family member, and wanted a way to use it via Bluetooth with my smartphone. The cell2jack does exactly what I need it to do. The phone I tested this with was a 1970s touch tone desk phone (I do NOT currently own any rotary dial phones with modular (RJ11) jacks, so while cell2jack says that this WILL work with those phones, I don't have a way to test that (yet)). Pairing is simple: just plug the USB cable (which is admitting short) into a wall adapter like the one you use with your smartphone (they do NOT include one in the box... you have to supply your own, which isn't a big deal, and while the included USB cable is short, you can swap it out for ANY USB cable if you need a longer one), plug your RJ11 cord into both your phone and the cell2jack (also not included, but that's expected), and then take your landline phone off-gook, and dial #*# (a voice prompt will tell you to pair it to use it). Then just select it within your smartphone's Bluetooth devices, and connect to it. The cell2jack essentially turns your landline phone into a Bluetooth headset for your smartphone. One thing I will say about the cell2jack is that I believe there is supposed to be a dial tone emitted from the landline phone connected to it (just as if you were using a regular landline), but I got no dial tone when I picked up the receiver. However, the touch tones still worked, and the calls were patched through to my smartphone immediately. This may cause confusion for some. Receiving calls works well, and the mechanical bell ringer on my vintage landline phone started ringing at the same time my smartphone did. In both cases (making and receiving calls), when I hung up the handset of my vintage landline phone, the cell2jack disconnected and ended the call on my smartphone almost immediately, which is great. I haven't yet connected the cell2jack to a landline phone with built-in Caller ID, so I'm not sure if the CID information from my smartphone would pass through to a connected landline (I will be trying this in the near future). You can apparently also hook the cell2jack directly to an RJ11 telephone jack in your house, and ALL landline phones in your house connected to other RJ11 jacks will work together as if you had landline service. This is also something I have not yet tried, and don't have any intention to, as I have landline service as well. Another feature I haven't tried yet and would like to try is the built in pass-thru for a smartphone's voice assistant (i.e. Siri or Google Gemini). I will have to try that soon as well. Finally, I love how small the device is. I'd assume that, if you had enough space inside the casing of your landline phone, you could put the cell2jack right inside of it and hide it, although sitting behind or right next to your landline, it still looks good. Whether you're a vintage telephone collector, or just want to keep your landline phones hooked up after you disconnect your landline service, the cell2jack delivers. Sure there are more expensive devices like this out there, but the cell2jack delivers on what you'd expect one to do for a great price. Highly recommended!

works right out of the box
Was delivered within hours using Prime and packaging was excellent. Setup was super easy and took very little time. I have an old wall mounted rotary phone salvaged from a home demo and I wasn't even sure that it worked, but with in a few minutes I was making and receiving calls from the old phone! Not only was I able to talk, but there was a dial tone, the rotary pulse worked, and the old ring tone from the internal bells rang for incoming calls. What a blast from the past! Those of us who grew up with these old phones will find that once set up, they operate exactly the way they did decades ago. Perfect for nostalgic people, those who want less technology, and older folks who struggle with their modern phones. A couple of small gripes; the power cord is very short and uses USB micro instead of USBc, and there was no adaptor plug provided. Not a big deal for me because I have lots of extra plugs and power cables. Just know this before giving one to grandma. Overall an excellent purchase, good value, easy setup, and perfect performance.

CELL2JACK, Panasonic Home Phone, Android Cell & Google Voice Perfect Trio for Seamless Connectivity
I recently rediscovered my old Panasonic KX-TGE270 home phone system (complete with four handsets and a base station) while cleaning out a closet. Originally purchased for my in-laws during a temporary stay, the phone system had been gathering dust since they left. With a desire to repurpose it and add a reliable, cost-effective backup to our smartphones, I came across the CELL2JACK box—and it turned out to be a game-changer!Key Features & SetupThe CELL2JACK device is affordable (under $40) and simple to set up. It connects your existing home phone system to your cell phone via Bluetooth, essentially transforming your home phone into an extension of your mobile service. I paired it with an old Android phone and integrated it with Google Voice, taking advantage of their free calling service.The installation process was a breeze, and within minutes, my Panasonic system was operational again, fully synced with my Android cell phone and Google Voice account.PerformanceThe system works flawlessly for both incoming and outgoing calls. It’s a perfect solution for anyone looking to maintain a landline-like setup without incurring monthly fees. The audio quality is excellent, and the Panasonic handsets perform as well as they did when I first purchased them.Why It’s a Must-HaveCost-Effectiveness: For a one-time payment, I’ve revived my home phone system and connected it to Google Voice, making calls essentially free.Reliability: As a backup to our smartphones, the home phone setup ensures communication continuity, even if cell service is disrupted.Ease of Use: No technical expertise needed—just plug, pair, and play.Final ThoughtsThe CELL2JACK box is a brilliant device that bridges the gap between traditional home phones and modern mobile technology. Combined with Google Voice and a spare Android phone, it’s a fantastic way to create a reliable and cost-free communication setup. Highly recommended for anyone looking to revive an old home phone system or add redundancy to their mobile devices!

Works. Sometimes noisy. Extension phones can be a bit different for talking.
Works. Setup is pretty straightforward, just follow the instructions. Works well for one old phone at a time. You're cell phone works as usual. If you answer on your cell you wont hear anything as all the audio is switched to your phone line. You can answer on your cell or your old phone and talk on the old phone. I have it connected to my house line so I can plug in extra phones like I used to have it with my land line. We used to have 'conference calls' which different people on each hand-held phone. I can pick up on either phone but if I pick up the extension, and then pick up the phone closest to the cell phone, it will cut off the extension. If I pick up the phone closest to the cell, then the extension, I can hear on both and use it like I used to. I noticed that the quality of my extension phone is much better than the phone next to the cell. Oh well. There is some noise when using both old line phones at the same time and it is a bit hard to hear on one of them (the cheaper one) - wish there was a volume control to get more volume. When using any one phone, it is fine. The background noise is not really noticeable on either of my phones although my extension phone's background noise is nonexistent and the volume is higher. It is a better phone though, one from an office. I like it and am glad I got a good working cell2jack so I can pick up my phone in the other room instead of running where the cell phone is. Would definitely buy again. Edit after a couple of months: Not always consistent. Sometimes just gives silence when picking up a call and the other person gets silence also - no contact made. Recently, did not trigger the answering machine but went to voicemail on the cell phone so did not know anyone called. Also, most times now, does not connect call when pick up extension. Not reliably working.

What a FANTASTIC product!!! Use you antique or modern phones with your cell phone!
What a FANTASTIC product!!! Use you antique or modern landline phones with your cell phone! For years we would joke about having a rotary cell phone and now I do! All I do is use it for talk if I need to do anything requiring complex touch tones (like banking business for instance) I just use the cellphone or regular house phone. For rotary phones the asterisk (*) equivalent is 11 and the pound (#) sign equivalent is 12. The setup procedure requires you to connect your wired phone to the Cell2Jack and dial # * # in order to put the Cell2Jack into pairing mode to pair with your cell phone. Since I was using my antique rotary phone I dialed 12 - 11 - 12 with the dash representing a 2 second pause between entries. It worked PERFECTLY! The light started to blink indicating it was searching for my phone. When I put my phone in search pairing mode it found the Cell2Jack. It took only 2 tries to pair successfully. Thus far every time I approach the Cell2Jack with my cell phone it automatically pairs with NO issues. I have NOT had to re-pair it. For what it's worth, I have only been using Cell2Jack for 3 days so more experimentation is needed. Those I call say it sounds fine - just like an old phone! I want to experiment more with other phones but if this phone from 1928 works fine ANY phone should work! With this device you could literally power it from your car power jack and have a rotary phone in your car! I'm not sure just how practical that would be but you'd surely be the first one on your block (or neighborhood) to have one! So my initial impressions are VERY FAVORABLE especially that it only cost $29 on Amazon. It is being offered as of Jan 2021 on their website for $26 and free shipping but with Amazon I had it the next day. So if you think you would like to be REALLY different and have just about ANY phone you want as your cell phone this is for YOU! I love it! This is GREAT! It supposedly supports 2 cell phones which is something I don't need, but regardless, I could not find any reference to this on their rather simple website. It also supposedly can support 5 ringers, i.e., 5 phones with working ringers but I don't need that either so I did not test this capability. For more than one wired phone you will need a splitter as there is only one (RJ11) phone jack. They also recommend using a robust wall-wort phone charger power supply so apparently this thing does draw a bit of current and a good power supply will ensure proper operation. A power supply is NOT included but for $29 I would not expect one and I am fine with this as I have so many of those things lying around anyway. I wanted this SPECIFICALLY so I can use my antique phones so I did not test it with any modern touch tone phones. There is another company called X-Link marketing one of these gadgets at 3 times the price ($89) that I think may have more capabilities but for me this one is fine! So if having one or more landline phones as a cellphone this is a MUST HAVE!

Useful when charging, but with some flaws
I've been using this for roughly 3 weeks & I've found while it does allow me to continue using my Panasonic KX-TGD220 (wireless phone) using my cell as the main, it does have some flaws & ultimately I decided I was only going to use it while charging the phone. First thing you'll need to know is that it's best to leave your cellphone next to the Cell2Jack when you intend on using a phone connected to it, this allows for the strongest signal to the phone. Most people will have their cell on them when not charging it, so it may be more ideal to speak on the cell instead if not near the Cell2Jack as you'll get a better signal that way. I have found that I don't get a very good signal on the cell in the bathroom (no windows & I have a metallic roof), so this is one case where it's more ideal to use the cordless phone over the cell. Ultimately the first priority in a strong signal is your cell phone before even considering placement of the Cell2Jack, so consider that first by finding out where your signal is strongest where you live. Second point I'm going to go over, the Cell2Jack puts itself into pairing mode automatically when powered up if not able to pair with a previously paired device (or if this is your first time powering it up). This could be a bit of a problem if somebody close by accidentally hijacks the device with their own cell, but it's fairly simple to re-pair to your own cell by entering a keypad code on your phone, just something to keep in mind if you start getting calls on your phone that aren't getting to your cell (the cell should display calls coming in as you get called on your phone connected to the Cell2Jack. This will likely only be a problem if there is a power outage/flicker while you are away from home or if your phone is powered down. Third point is going to cause some problems if you are calling (or receiving calls) from automated systems; it seems the dial tones don't correctly go through to the cell, so you're likely going to find that you'll still need to use the keypad on your cell if you have to navigate automated systems that require keypresses (dialing phone numbers is not a problem however). Forth point is related to picking up your voice. I've noticed that if somebody is talking or making noise through the phone (this includes wind going by an open window while driving, other background noises or even loud static on a call), it seems that your phone will stop picking up your voice (pretty common with bluetooth communication devices from my experience), this wasn't an issue I had when I had wired or VOIP phone service. If you're patient & can wait for a particularly talkative person to stop talking, this shouldn't be a problem, but when it comes to talking with my mother, she's constantly cutting me off, so I find myself repeating myself quite a bit using my phone with this device... In regards to Caller ID, it doesn't seem to register correctly on my cordless phones. There's a key code you can supposedly press in the instructions to make it carry over, but I haven't seen it work yet (at least not fully; it does show a phone number, but no name)... Even if you have a phone that is capable of caller ID, you may find that you're still going to be using your cell for caller ID (which can be a bit troublesome if you are using a multi-handset wireless phone). Additionally, keep in mind if the Caller ID isn't functioning correctly, any phones that rely on Caller ID to set the time on your phone will never update to the correct time (as is the case with my wireless phones). In regards to using Voice Assistance, a lot of these functions may not work if your phone is locked, this can be an issue if your using a partyline (or multi-handset wireless phones) to access those functions from a room other than where your cell phone is. Final statement is while Cell2Jack can be useful making phones available in areas that would normally be deadzones or having a poor signal on your cell in your home, a bluetooth headset might be a better choice unless you already have a wired phone with functions you want to retain access to (like an answering machine, block list or programmed quickcalls), Cell2Jack just eliminates the concern of battery life when it comes to wireless communication devices.

So Happy to find this solution!
So Happy! My brother is having memory problems and is in a facility that does not have phones in the room. We tried the Ooma, and it would be ok except the wi-fi in the facility was a little unreliable and the device turned off frequently. Enter the CELL 2 JACK - I bought a Walmart tracfone and paired it to the facility wi-fi, then brought a phone from home and hooked it all up (very easy), and now the phone works just like a house phone: pick up the receiver, get a dial tone, and make a call - really that easy! Pick up the receiver and answer a call - no delay! Using the facility wi-fi means almost no data is used from the year-long plan included with the tracfone. Low cost, works perfectly!

Perfect Way to Use an iPhone With a Classic Landline Phone
I bought the Cell2Jack so I could use my iPhone with a traditional landline phone, and it does exactly what it promises. The included instructions are clear and made setup quick and easy. Pairing with my iPhone worked the first time, and both making and answering calls on the landline phone has been reliable. One thing I really like is how small the device is. It easily fits inside the case of my 1980s AT&T telephone. I used a very short telephone cable between the phone and the Cell2Jack, and only needed to run the USB power cable out the back, so everything stays neat and hidden. I also find voice calls much more comfortable on a real telephone than on the iPhone itself. The audio is easier to hear, and holding a handset for longer calls is simply more pleasant. If you prefer using a traditional phone but still want the convenience of your iPhone, this is a great solution.
