How to forward an analog telephone line to a mobile phone?

Question

Telephony

The task is to select equipment that could raise a certain SIP server, to which I could connect from a mobile phone with any application for SIP calls, and then so that it would make calls through an analog telephone network. Simply put, I need to call from a mobile phone through an analog telephone network. Well, it will not be bad if I can also receive calls on my mobile phone coming to my home analog phone. There is a static IP at home.
Yes, I know that you can connect IP telephony. But I need to make calls through an existing analog telephone line with a specific number.
There are already many discussions of this issue, but everything is in the context of offices, with a bunch of equipment. I just need one piece of iron, which will give access to an analog line via the Internet. I would like something in the region of 3-5 thousand rubles. What can you advise from experience?

Answer 1

You need a VoIP gateway with an FXO port. Then there are two ways:
1) Find such a gateway, which can also be a SIP server and you will connect to it from a dialer from your phone. It seems that even the cheapest Dlink can do this, at least I had to make a bunch of two links to urgently forward the phone through the factory. But this fact needs to be specified from model to model.
2) Take _any_ gateway with the specified port and connect it to any sip server (it can be installed in a virtual machine or directly on a computer.

Answer 2

Some kind of mess in the question and head. There is voip technology, there is analog telephony, there is GSM. They all work differently. What handset will you have in your hand (cell phone or fixed)? What technology is used to provide you with a telephone number (analogues, voip, gsm)?

Answer 3

Asterisk decides. Put a card with an FXO port into it, bring copper to the port. Of course, you will have to wrestle with the settings, because the task is very non-standard, but generally speaking, the asterisk has everything you need, and it can be of different designs - you can find a ready-made "black box" configured through the web face.

Answer 4

Grandstream HT-501 (like correctly remembered) FXO-SIP gateway.
If you manage to connect to it with a SIP client (softphone - you're lucky), if not - you need a PBX server, it's also a PBX, it's also Asterisk.
I can set up an Asterisk scheme (cloud virtual server) for you - your HT-501 hardware + softphone, as well as redirecting calls to a mobile phone when the softphone cannot connect.
The server can be yours (150-200 rubles per month rent, the cheapest) or not yours, it doesn't matter.
You still have to buy a piece of iron (FXO-gateway).
