PS - after originally thinking you were crazy to want to do this, @Stefani, I’ve been thinking about this a surprising amount since you posed the question last night. I’m actually starting to warm to the idea now
The picture shows an old BT style phone which will have a mechanical bell (I think, don’t know the exact model). Looking online what power was required for the standard BT Type 59 bell, and it’s about 3.2W. Phones without physical bells will draw much les than this.
Hehe love this, you should do it, Gareth! Totally agree with that guy on youtube. There’s heaps of gorgeous rotary phones available on Etsy and eBay. I’ll probably buy another one just because the design is so cute.
Thanks so much everyone for your advice and comments so far, very much appreciated. I am still waiting to receive both the phone and the cell2 device in the mail and will update everyone once I’ve received them and tried swapping out the cable
The Cell2jack website does say that some phones may not ring. There is a setting to increase the ring power, but it says that even then some may not ring. It recommends buying a ring amplifier in these cases. These connect in line with the telephone and will give an audible ring themselves.
