[GreenKeys] O/T - 24v to 48v POTS Telco converter for added ring?

[Cory Heisterkamp]

One other option would be to pick up an old Panasonic Easa-Phone PBX, such as the 308. It converts pulse to touchtone instantaneously, has generous ring current for the old mechanical ringers, and allows you to call between other sets in the house if connected to separate ports. No modification to the phones are necessary, and it can be hidden out of sight. I have ours connected to an OOMA VOIP box over WiFi and it works pretty well. -C

I’ve seen the combo Grandstream boxes with the FXO port (I already have one with two FXS ports).  There used to be a Piranha USB-FXO adapter and the Sangoma USBfxo, but they no longer seems to be available…

> Hey all you Telco guys - need some help!  So I’ve just bought a call blocker for my POTS.  Normally at my deck, I have an Automatic Electric model 80 (rotary) here and it has always worked great on my phone line.  Hooked it up today to the phone blocker and welp, the bell won’t ring and it won’t really dial out.  Measured voltage on the phone side of the call blocker and it measures 24v, unlike the 48v going in :/ .  Question… would the unit in the link below be the cure-all to this low voltage blues?:
