I have nothing connected to the wall phone jacks in the house, but I have a cordless phone in every room.

It's up to the OP if he wants to waste the $10.

Do you plug your phone into one of the Internet connectors on the Xfinity modem/router or do you plug it into the Phone connector?

Do you believe you could plug additional phones into the modem router using the Internet connectors and one of these kits?

If the adapter doesn't work, you just return it to Amazon. No waste.

I use the phone connector on the modem, but I don't think the ethernet connectors are set up for the phone service. I do use the ethernet connection for my desktop computer.

Exactly. The ethernet connection used by the VOIP phone in the room of the facility will not be set up for phone service either which is why the Amazon device will not work.

Again, why does Amazon sell an adapter that doesn't work? Apparently, the OP's phone system is set up to use a phone. The only way to determine if the adapter works or not is to order one and test it. Neither one of us knows what type of system the OP is referring to.

The adapter works perfectly well FOR WHAT IT WAS INTENDED TO DO. It provides a conversion from a telephone connector to an ethernet connector to enable using ethernet cabling to carry telephone signals. What it DOES NOT DO is convert an ethernet signal into a telephone signal.

The OP provided the model number of the VOIP device in the room. I have used similar devices and others on this thread have installed similar devices.

If you have an RJ-45 then you probably have the TCP/IP protocol or UDP or perhaps some proprietary protocol. A “regular phone” will not speak any of these. Converting to RJ-11 will accomplish nothing. If you see an RJ-11 jack then a “regular phone” will probably work. If you see an RJ-45 jack then you are probably looking at a VoIP phone. This could also be something like an Ooma box that plugs into an RJ-45 jack and then a “regular phone” plugs in the RJ-11 jack on the Ooma box. The OP should work with the appropriate staff at the facility.

"An RJ45 to RJ11 converter cable is designed to connect your RJ11 devices such as analog phones, answering machines, fax machines etc. through a VoIP RJ45 Ethernet port. Since the RJ11 only uses four wires, it will only work with 10/100 Ethernet. 1 Gigabit Ethernet requires the use of eight wires or leads. Jun 27, 2023"

If these adapters don't function as stated above, why are thousands of people buying them from Amazon? I cannot believe that these people are not using them to connect and use a regular analog phone to an ethernet jack. I used one myself when I had a VOIP phone service. I do agree that it is possible that the proprietary system used by the assisted living facility could prevent the adapter from working for security reasons.

From what I've read they are using the converters to carry the analog signal to their modem's phone jacks when they don't have a standard phone jack RJ11 in that room. They convert standard to ethernet then at the modem convert back to standard RJ11 and then plug that in the analog phone jack on the modem. Essentially just using the cable to carry the signal. However there does appear to be certain specific analog to digital converters that may work allowing the connection of an analog phone. They are pricey though...

Phone lines

Analog lines, also referred to as POTS (Plain Old Telephone Service), support standard phones, fax machines, and modems. These are the lines typically found in your home or small office. Digital lines are found in large, corporate phone systems.

How do you tell if the phone line is analog or digital? Look at the back of the telephone connected to it. If you see "complies with part 68, FCC Rules" and a Ringer Equivalence Number (REN), then the phone and the line are analog. Also, look at the phone's dialpad. Are there multiple function keys? Do you need to dial "9" for an outside line? These are indicators that the phone and the line are digital.

A word of caution. Though digital lines carry lower voltages than analog lines, they still pose a threat to your analog equipment. If you're thinking of connecting your phone, modem, or fax machine to your office's digital phone system, DON'T! At the very least, your equipment may not function properly. In the worst case, you could zap your communications tools into oblivion.

How? Let's say you connect your home analog phone to your office's digital line. When you lift the receiver, the phone tries to draw an electrical current to operate. Typically this is regulated by the phone company's central office. Since the typical proprietary digital phone system has no facilities to regulate the current being drawn through it, your analog phone can draw too much current—so much that it either fries itself or in rare cases, damages the phone system's line card.

What to do? There are digital-to-analog adapters that not only let you use analog equipment in a digital environment, but also safeguard against frying the internal circuitry of your phone, fax, modem, or laptop. Some adapters manufactured by Konexx come designed to work with one specific piece of office equipment: phone, modem, laptop, or teleconferencer. Simply connect the adapter in between your digital line and your analog device. That's it. Or you can try a universal digital-to-analog adapter such as Hello Direct's LineStein®. It works with any analog communications device. Plus, it's battery powered so you're not running extra cords all over your office.
