Can IP VoIP communicate with traditional telephones?

Yes, but after the gateway conversion, the traditional telephone is based on circuit switching, and the IP network telephone is based on IP packet switching, and the Voip gateway can realize this function.

IP Voip is a generated IP packet, which is routed to the nearest network computer room (operator computer room) of the called traditional telephone party through lan switches and router, and then converted into an electrical signal through the Voip gateway in the computer room, which can be transmitted to the traditional telephone line, and then transmitted from this computer room to the ordinary landline you dialed through the ordinary telephone line. The general principle and path are as follows.

There are many deep things in it. If you don't understand, you can keep asking me. I'm happy to answer. Thank you! ! !
