very good but dialing function does not work in my country
the device provide an amazing and swift integration between mobile phone and old rotary phones (or any other dial phones). no programing is required and ringing quality is good, I used it with socotel 63, worked like a charm. however I cannot use it for dialing. after referring back the problem to Cell2jack support team, they confirmed that in this stage their support and focus is on US market and they are adopting their dialing conventions. currently I am not using it awaiting any further updates to add a leading zero dialing function.

Funciona
El único problema que he detectado es que no permite cortar la llamada entrante no iniciada desde el teléfono no celular. Es un problema menor. Respecto al alcance del Bluetooth para que el celular se conecte al dispositivo indican que debe estar al lado uno del otro pero en mi caso he probado a más de 10 metros en habitaciones diferentes y seguía funcionando. Por lo demás funciona según lo que prometen.

Perfect
Wonderful! Once purchasing the right landline with loud volume the set up was easy. Connects with a mobile and has adjustable settings. Highly recommend for young kids and family. Works as a family mobile that can be taken when going out, then put away and used as normal landline at home ✔️✔️

Works great on a 1970s Bell Telecom rotary phone (Canada)
Works great! I bought an authenic 1970s Bell Telecom (Canada) rotary phone from Poshmark that I want to use as a landline. The phone rings loud, and even rings if someone calls me on WhatsApp or Messenger. At first I had an issue where the receiver was too quiet and I could barley hear the person on the other line. I learned that you can download a Cell2Jack software on your computer, where you can plug it in, and adjust the settings from there. I turned the receiver volume up to 4 (max) and can hear people much better. Another issue I found was that the person I was speaking to said they keep hearing themselves echo, and its distracting. I played around with the Cell2Jack echo settings but was still having the problem. Eventually I figured out that the reason why it was echoing was because my cellphone was right next to the landline. When you're on a call, your cell phone shows that its in a call with the audio to bluetooth (Cell2Jack), so they were hearing themself echo because they could also hear me through my cellphone. Once I started placing my cellphone in another room or away from where I was, the issue went away. So far, its great! In Canada, they are shortly discontinuing all copper wired landlines and switching over to internet landlines (Bell Fibe, etc.) so soon, it won't be possible to use these old vintage telephone. I am really impressed that something like the Cell2Jack is compatible with a phone thats 50+ years old. I definitely recommend this product.

Cell2jack - Adaptateur de téléphone Portable vers téléphone Domestique.
Super produit. Au départ, il recevait les appel mais impossible d'appeler avec le téléphone fixe. J'ai du mettre a jour le firmware pour règler le problème. Le site web de Cell2jack explique toute la procédure de mise a jour. Maintenant tous fonctionne correctement. Cell2jack fonctionne avec un téléphone Ericsson U43 et un Socotel S63 avec clavier DTMF.
