Should a German phone work when connected to a US phone jack?

Re: Should a German phone work when connected to a US phone jack?

Although the common frequency used in the United States is 20 HZ and in Europe is typically 25 Hz, it can be any frequency between 15 and 68 Hz.

It is more likely to be the ring pacing and not the frequency. Have you checked the IN PBX setting? PABX and PST ringing patterns are not the same. Many fax machines and other devices that have electronic tone ringers instead of actual bells will not respond if either the length of the ring, 1 or 2 seconds and the length of the pause between rings is not correct. PST ringing is 2 seconds on 4 seconds off. PABX might be 1 second on and 5 seconds off and will not always be detected by the timing circuit if the setting is not correct.

Whilst I felt what I was told about the frequencies made most sense, I did just change the one and only setting it offers relating to PABX from No (Nien) to Yes (Ja). Here's Google Translate (I only have the German physical manual, no PDF):

I changed that one setting (using Google Translate Camera to understand the German language shown on the LCD screen) and IT WORKED! The fax now picks up. (Note, the phone still doesn't ring which may still be the frequency issue, but it works for what I need.)

To summarize what I had to do to get this German Samsung fax phone working in the USA:

1. Wire the two middle RJ11 wires to the two outside wires
2. Change the PABX setting to extension (although it's not an extension)

Thank you!!

If you want to hear when a call come in, there are always external bells and tone ring devices. I even helped with a system setup in an audiologist office where they did as little extraneous noise as possible, i.e. no phones ringing. We used a relay system to flash a light at the receptionist desk and the nurses station.

Good to know. Actually silent fax reception is perfect for us.
