Older phone ringing issue

We have two older phones, a Western Union stick phone with a separate ringer box, 51 series, and a Western Union 302 desktop. The stick phone will ring with both phones connected to the line. The desktop phone will ring only if the stick phone is not connected.

Seems likely to be a voltage issue. A ring booster mentioned elsewhere here is pretty pricey and may be difficult to install at our property. Both phones used to ring together, but that stopped a few years back. Any suggestions appreciated!

Welcome to the forums.

Some pretty obscure equipment there. Some old jewels. The problem is those oldies require a heavy ring current. Depending on what you have for phone service..... there just might be enough able to run them. If you have any type of cable phone service.... the ringer voltage is generated inside the modem and it is not strong.

Some pictures of what you are working with would be helpful..... How-to-insert-pictures.

If the phones have been 're-manufactured', there should be a label on the bottom with a Ringer Equivalance Number (REN). Total the RENs of all the phones on the line. IIRC, the maximum load (total REN) was 5.0, but may be less.

If they are original, then a 'ring booster' is the only way you'll get them to work.

As mentioned by ThisOldMan the REN load may be an issue, the 302 should not have to high REN load. The other one could probably be adjusted with a suitable capacitor or resistor. If both ringers were connected in series, bouth would probably ring, that is what they did in the relly old days. The specialists will be here:
