Receiving calls on the computer?

Question

Telephony

Let's say there is a computer with a headset and the Internet. I need to be able to call, and I could answer on the computer. If I'm not online, calls should be forwarded to my mobile. There is no fixed telephone connection.
I considered the following options:
- buy a direct Moscow number from a sip-provider: it's expensive, and I don't need it, the federal one is quite enough. Cellular operators distribute them for free along with SIM cards, so why don't sip providers do this?
- plug a cellular modem with support for voice calls into the computer and use some kind of program. Is it possible now in Moscow to buy a modem that can do this for reasonable money?
What else do you recommend?

Answer 1

The megaphone has a multiphone service. just what you are talking about

Answer 2

If you develop the second option, you can receive calls directly to your mobile.

Answer 3

In principle, the MTS-connect package, you can both SMS and call there, but I don’t know the tariffs, and probably any software with a 3G modem supports this function ...
Although, as was said earlier, it’s easier to communicate using a mobile phone, because on a computer sound quality will depend on your headset (microphone) and sound card, respectively.
Well, skype is just for such things.

Answer 4

And what's stopping you from taking a landline number from a mobile operator and receiving calls on a headset on your mobile?

Answer 5

skype, right?

Answer 6

MTS is now developing www.corp.mts.ru/complex_decision/_fmc/ perhaps in the future it will be possible to see an analogue of a multiphone in them. But at the moment only the multiphone works.
