Cell phone to POTS to WiFi

Say, the following device :  D-Link 3G FLLA Wi-Fi Model DWR-720/PW   takes a SIM card and allows one to mkake telephone calls from the built-in handset. It also offers wifi to the user. We are loking for a device with similar functionality as described, except that it does not need a handset but rather a FXO Port allowing one to connect in a regular POTS.
The important features are the Wifi for the end user and the ability to plug in a POTS. Cost is a factor and availability in South Africa is preferable. Kindly suggest devices ofering this functionality.
PS.  This device is being used as a replacemenent to a traditional analog telephone

The problem when combining old and new technology, is that the resulting function is very useful for the current people to use.
Therefore, when you combine SIM / WiFi Hotspot / FXO port together, you will end up with a router that can server 3/4G internet to WiFi users AND make phone calls using an old analog phone. But one caveat, I said, most useful function. That means, the phone calls, go through the DATA SIM, through a VOIP provider!
You use case however, is very unusual, and therefore I doubt there will be any hardware available for you.

The closest to what you're asking for are going to be VoIP phones, which doesn't meet your requirement.

Remember that the phones would use TCP/IP, so it actually makes more sense to use SIP than POTS. Besides, with copper lines going away in many parts of the world, there is far less motivation to actually make the kind of device you're asking about.

I dont know the environment this is going into, you would have some wifi phone possibilities if you were to install an IP PBX that is capable of leveraging POTS lines. But is that worth it?

It has been a very long time since I have seen a device like that. Phone companies here normally provide DSL now. It was a Barricade unit and is long gone

I suggest you contact your Telephone company or ISP to see if they have a unit that will work for you

Many ISPs provide this tech by default... well... similar to what you describe...

For example, I use Google Fiber with POTS lines. Each line is... either $5/month or $10/month...

Each line is implemented by a POTS <-> VOIP converter provided by Google.
I agree with the earlier comments --

Closest I think you are going to get is a CradlePoint or Sierra Wireless Cellular interface and a standalone FXO adapter -

Say can you find any other companies making this type of product as perhaps they have what I'm after: https://www.d-link.co.za/for-home/accessories/flla-phone

Commented:
POTS lines are not in demand anymore so I think you will have a hard time finding what you are looking for.  Verizon offers a cellular to POTS line unit but I do not think it has WIFI data.  here is the link https://www.verizonwireless.com/home-office-solutions/wireless-home-phone/

Commented:
I would also think you should contact the carriers in the area where the devices would be used to see what they offer and what they support.

Commented:
you could consider a Cradlepoint as suggested above and an ATA and a small wifi router.  here is a link to an ATA http://www.grandstream.com/products/gateways-and-atas/analog-telephone-adaptors/product/ht802

In terms of hardware, something like the Linksys SPA 1001 analog telephone adaptor (ATA) would connect a POT (e.g. cordless phone base station) to the internet via a suitable VOIP service. I have used one for many years but you have to set it up with your chosen VOIP provider such as Sipgate and/or a Betamax service. It is a fairly cheap solution.

There are lots of wifi phones that will connect to a VoIP system. But as I've been mentioning, exactly what you're looking for doesn't exist.

Sorry, I quoted the wrong product - this one has an FXO port to allow PSTN as well as VOIP connections.

Say, I'm aware of alternate ways to solve this problem. There is a device that solves it (I mentioned it in my question). I'm looking for a device with similar functionality but with an FXO port

Commented:
The SPA3102 mentioned above has an FXO port.
Distinguished Expert 2018

Commented:
  1. The SPA3102 is a long discontinued device.
  2. Your requirements included WiFi.

Correct me if I'm wrong, but it sounds like you basically want a WiFi router that can leverage either a SIM card or DSL line for internet connectivity. If that is the case, then you can look at something like the TP-Link Archer MR400 or Archer MR600. The differences between the models is 1) speed of the WiFi network, and 2) whether the Ethernet ports are gigabit or not. However, note that these devices do NOT have FXO ports, which would mean that you would need a separate DSL modem (or router simply configured as a passthrough).

If what you want to is to be able to leverage a POTS line from WiFi for phone calls, then you're not going to be able to do that.

What is the purpose of the FXO port? Telephone or internet?

Telephone - good old POTS

How many phones are you hoping to connect? And how are you expecting to connect the phone(s) to the POTS line, WiFi? You're asking for something that doesn't exist.

Closest you might get is if you get something like the router that I cited, then put a VoIP PBX behind it. That way, you'll be able to use WiFi phones (which would leverage the PBX) if you wish.

One regular analogue telephone instrument and one to three wifi enabled devices must connect to it to get internet
Distinguished Expert 2018

Commented:
I've provided you the best scenario. But I have to ask, why does the POTS line need to connect to this device?

Commented:
So as to provide voice communication for an old type analogue phone intrument
Distinguished Expert 2018

Commented:
There aren't telephone outlets available across the house or office this is will be in? If you have a POTS line, this device would actually be adding an unneeded step.
Not sure how many people are going to tell you it's not something commercially available these days.   Before you believe us.

So as to provide voice communication for an old type analogue phone intrument

Also to clarify FXO ports face the Central Office and accept Ring and functional voltage from them.  FXS ports face a station (phone instrument) and provide ring and functional voltage.  So you need to look for an FXS device not FXO based on the above quote, and the closest you will probably find, as everyone has told you,  is a LTE to LAN / WiFI router and an ATA adapter.

Commented:
Tx for the correction - FXS port is needed. D-Link have made a device offering a similar functionality (please see the device I mention in my question) but without the FXS port.
Its quite possible that a smaller manufacturer has the device we are seeking.
The SS10 device offers the FXS port but not the WIFI connectivity. https://issuu.com/britsvanwyk/docs/ss10_grace_new
It was from the error of Cellular least cost routing. It seems feasible to me that someone has added the wifi functionality to such a device.
I'm looking for this in the home use application.

Commented:
As it is the FSX port you seek (without FXO support) , my original post suggesting the Linksys SPA1001 may suit your needs at fairly low cost.

Tx Mike but this is not what I'm looking for. Pls see my most recent comment
Distinguished Expert 2018

Commented:
So in using your POTS phone, you want to use it over the mobile connection, correct? That's the major clarifying point here. Everyone was thrown off initially because you were telling us you wanted to use a POTS service, which would be a very different matter.

The device you might be looking for could be along the lines of this DWR-956M?

Commented:
Correct. This is too advanced. VoIP is not needed. Fibre is not needed. Pls see my recent comment above
Distinguished Expert 2018

Commented:
I've read your comments. That is literally the only DLink model that will possibly work for what you're looking for (just because it supports fibre doesn't mean that you have to use it). I am willing to bet if you check with your carrier, that's going to be the unit that works for you. There is no Dlink unit for Telkom that includes an outlet for connected a phone directly to it other than what I've just provided you.

The only other device I've found is this Huawei: https://secure.telkom.co.za/today/shop/home/device/huawei-b525-router/
Say, If you look carefully at my comments - everyone has looked at solutions from well know brands. No one has considered exactly what I'n after.
