r/TelephoneCollecting

I'm trying to connect a rotary phone to my modem/router. I've already added a landline to my provider and I cannot get a dial tone. The phone itself i know for a fact works. I was just in use a few months ago before it was gifted to me. I have a RJ11 cable. I thought connecting that to the modem and the phone would work but it didn't. Do I need to buy an ATA? And if so, should I buy a dialgizmo pulse to tone converter or should I buy a Grandstream HT801?

Mk1 of all telephone pcbs I'm trialing for my pbx.

top takes 4 rj11/12 and puts it onto one Rj45 so I don't need to make 4 long rj11 cables.

The bottom left cab then take that Rj45 and convert it back to rj11 but it also has a pass through Rj45 so you can run from the pbx to each phone location. It has jumpers to select which ring tip pair you are connecting too or the top board.

The third board is my first attempt to build a ring capacitor for British phones normally found inside the master socket. It needs tweeking as the hole size is too small and I want to change the header to punch in cable connectors. Although I need to edit the design my idea is that it would drop into the gpo 706 range and equivelant phones so they can be hooked into an Ata.
