Analogue to DECT converter

Feb 05, 2023 Last reply: 3 years ago 14 Replies

We have DECT phones, with the base station plugged into the analogue phone port of out router. We also have an old rotary dial phone, but the phone sockets are still connected to the master socket, which is connected to the unused landline.



I could disconnect the analogue sockets from the old master socket and connect them to the router's analogue connection, but that means going under the floor and running a cable through an inaccessible area under the extension.



It would be a lot easier to use an analogue to DECT converter on the one analogue phone, but has anyone seen one that is available, affordable and not tied to BT's home hub?


No, I'm not sure what the problem is. Surely you will no matter what you do, you will need to get a hard wire to that difficult place. T other thought is to find a place where you can get to and move stuff around so it can be wired. I'm not sure how many phones the router phone connections can take though, so it might be a suck it and see. I'm still on old copper since I seem to get more misdialled numbers on the voip, so Virgin put it back to copper. Brian

No. You can get (but they are very expensive or locked to BT) units that plug into the mains for power and into which you plug a phone. The unit then acts as a DECT handset, allowing it to communicate with your other phones' wireless base station.

All of our phones are wireless DECT phones, except for this one phone.

That is not possible. It is in the living room and is both functional and decorative - made between 1940 and 1947 from what I have read.

The router is in the conservatory. To be able to get the phone to a position where a wire could easily be run would require placing it in the extension instead of the main living room, but my disabled wife could not stand long enough for calls and the only location that I could get a wire to (without running across doorways) cannot have a chair, as it would be directly blocking the kitchen door or the door to the conservatory door.

There is no access under the extension floor, as it is surrounded by brick walls and the floor cannot be lifted, as there is laminate flooring, fitted under the skirtings. That is why it is difficult to get a wire from the conservatory, through the extension and into the living room.

A good question, but the DECT base station counts as less than one and the other phone should not overload it - if I could get a wire to it. If I can get a DECT adapter though, then only the existing DECT base station would be loading the router, so there would be no problem.

We're on Virgin too - and so far, we've had no problems in the 2 years that we've been with them.

I don't understand your post. I have an analogue landline (but BT say it will be changed to digital within a year, and new phones will be supplied). I have a cordless DECT phone with a charging master station that plugs into the landline, and a wifi router which also plugs into the landline.

You say your landline is unused, so where does your router get its input? My wifi router has ethernet sockets on the back - is that what you mean by the router's analogue connection? Perhaps your landline is digital?

There is no longer a landline. The Virgin router has a dedicated port for analogue phones, which it then digitises internally and communicates with the outside world over their own co-axial cable/fibre network. Effectively the port on the router acts as the equivalent to the BT master socket, but there is no dedicated external phone line.

The existing phones are one analogue phone (an old, rotary dial as it happens), which works fine plugged into the router and a DECT base station for a number of cordless phones, which also works fine plugged into the router.

I moved the DECT base station into the conservatory, where the router is and the cordless phones all work well. However, the old phone sockets remain connected to the redundant BT master socket at the front of the house. I can disconnect them from it, but to get the rotary dial phone working at its location in the living room, I'd then need to connect that wiring to the router's phone port.

The problem is simply inaccessibility to run such a cable - the router being in the conservatory and the phone wiring being under the living-room, with the two separated by two brick walls and an inaccessible space under the house extension.

What I am looking for is a mains-powered device that I can connect the rotary dial phone to and which, in turn, produces a DECT signal to connect to my existing cordless phone base station - effectively turning the analogue phone into another DECT cordless phone.

Such devices do exist, but they appear to be expensive £300+ or locked to the built-in DECT base station in a BT fibre hub and I am hoping that someone has seen a cheaper equivalent or how to unlock a BT device.

Rip off the skirtings, wire, and replace. In extremis chisel out plaster., lay in wires and reskim,

Either you need it doing (properly) or its not worth doing at all.

It sounds like he has a VOIP equipped router

Nope. Some ADLS routers take a baseband signal and present it at a POTS port and some have VOIP ports.

When he says hss landline is unused he may mean the BT master socket doesnt have a phone plugged in at all, #

OK. Consider the BT hacǩ. Run a wire to the outside of the house through a wall, and route it externally to where you need it. Its often a lot easier than internal and its only phone - doesnt have to be hi spec.

I think the consensus is such does not exist

I have ggogled in German, and found this:

DECT TAE DTL 2.0 DECT to Line Adapter

by a company called wantec... 100€ excl. VAT. But I haven't seen a suppier that actually can suplly one, yet.

Also: Gigaset 1000 TAE discontinued, but cheap on eBay. There's one with 10 hrs to go, currently at

1€...

That is a possibility, but I have been working on getting rid of external cables - there were far too many with aerial and satellite drops, etc.

I have found them, but I do not want to pay £300+ or to have to switch to a BT system for the much cheaper, but locked to BT version.

I have decided to do it another way though. For less than £40, I can buy an analogue to DECT unit and DECT to analogue unit. They will only pair with each other and not with the existing DECT basestation, but it will allow me to put one of the units by the existing base station and connect both the existing and new units to the analogue port on the router.

Yes some weird issues crop up apparently with no real obvious cause. Its one of those sub clauses of Murphys law I think. I do also use one of those telephone diallers via the microphone, and every voip I've used seems to have errors with them, though I fully realise this niche need is due to my blindness and the inability of most mainstream telephones to ffer speech for setting up memories. The Amazon echo and my smart phone can accept dictated numbers, but my brain cells seems to have the numbers equivalent of dyslexia. Brian

There are several Instructables on how to turn rotary phones into either DECT or VoIP phones by replacing the innards with a microcontroller.

Makes more sense to use your iphone and tell siri to call by name from the contacts.

So use the contact name.

I see. I take it there's no landline socket in the conservatory? If there were, you could connect it to your router via a jumper cable, and your dial phone might work as all the sockets are connected together. I also assume you can't move the router to the dial phone because the network cable is on the conservatory side of the wall.

A dial phone just shorts the line 10 times a second. Your router analogue output probably only caters for touch-tone phones, so you'd need a computer interface to convert the pulses to touch-tones if you wanted to dial out from your old phone.

There is, but the two halves of the system are disconnected from each other, as we were not using the conservatory sockets and the cable was removed due to fault.

The Virgin co-axial cable comes directly to the conservatory and the home server and network switch are in there. So moving the router would involve moving movre cables.

I have already tested it. The router is quite happy with pulse dialing (which did surprise me) - although a future replacement may not be.

I've decided to use a different option now anyway - I can buy a matched pair of sender and receiver, one end having the phone plugged in and the other plugging into the router's analogue phone port, in parallel to the existing DECT basestation. It seems a bit daft, as the pair operate via DECT, but will only pair with each other and not another basestation. Presumably they are not GAP compatible.
