I had a separate VOIP adapter that was independent from any router and modem. With such an adapter, you provide separate power to your phone. You also have to open the correct VOIP/SIP ports in your Internet router. Such an adapter isn't locked to your ISP, so you could subscribe to any VOIP/SIP provider on the Internet. I don't remember any more the model I used, but it looked similar to this:

Not only pulse dialing, but I imagine the big mechanical bell ringers on old phones might need more power to operate them than a modem/router is prepared to provide?

Yes, the on hook voltage is 48 VDC and the ring voltage is 90-130 VAC at 20HZ superimposed on the 48 VDC.

I got a Magic Jack which is a VOIP unit. Ported over my old land-line number to it. MJ unit can be taken anywhere when I travel and if an ethernet connection is available,  I am set. This is including overseas! If I don't want to be bothered taking the unit and a regular phone along, I can set up forwarding to my cell phone as well. The cost is just $35 for the unit and yearly cost is only some $35 bucks with no long distance charges at all. Even International rates are minimal.

In USA Comcast cable is up to 50..100 M, the newer Motorola cable modems have a VOIP POTS jack.

The cost is $10/line /month vs 40..60 for Frontie POTS copper.

In France we have 100 M fiber, with VOIP POTS line and included French Mobile all for EU30/mo

I have Comcast and it comes into the house on coax but fiber must extend to the neighborhood.  In any event, I get 1Gb speed from Ethernet and VoiceOverIP as a telephone jack on the cable modem.  The interface provides everything necessary for any plain old telephone including the 90V ringing.  I use a rotary dial phone just because I can...

Actually, I unplugged the telephone because the sales calls were coming in before I even knew the phone number.  In any event, I plan to stay with AT&T telephone service (which is carried on wire) because it has the superior 911 (emergency) service and that's important when you're really old.

Here we have fiber to the house. The state owned telecom company installed also a router that has jacks to connect 2 POTS phones.
I am using a phone that I bought in the 90's. It dials with tone
