Phone call to the office -> transfer a call from a specific phone. device via VoIP on PC?

Question

Telephony

Good afternoon!
The layout is like this.
I work in TP, we have a structure throughout the country, so the whole structure is in one Internet network. We have a direct landline number and several landline phones, I want to connect one landline phone to VoIP so that the call goes to my PC too when they call the office. Is it possible to do this or is it necessary to throw all telephony into VoIP?
PS I have never dealt with VoIP, so if possible, send it to the right address where you need it, thank you very much!)

Answer 1

Want to convert a regular handset to VOIP? Buy a gateway with FXO

Answer 2

You need approximately this device.
Register an IP phone (or softphone, in your case) on the gateway, give a number, set up transfer from the fxo port to the sip number assigned to the ip phone. Outgoing send to fxo - in fact everything.
If the gateway allows you, you can make several registrations like 222, 222p1, 222p2 - respectively, you can connect an IP phone and a softphone in parallel. If your network is scattered everywhere and flat, then you can use a softphone where you connect.

Answer 3

Perhaps you will need FritzBox for these purposes . This contraption is several times cheaper than the Audiocodes mentioned above, though you need to look where to buy it. There are two FXS ports and an FXO port. In addition, you can configure any redirect rules. And if you reflash this piece of hardware into a slightly older model, then a built-in SIP server will appear in it, i.e. own tiny IP PBX. Next, install any SIP client on your computer and connect to FritzBox according to your own rules.
