I got a call from a fraudulent group at my house.

The contents are "You are using the Internet!" "Yes, you are using it." "This is a management site." I don't know what the management site is, so I talked to each other. Annoying with a funny phone. I tried to buy an answering machine, but it seemed like it was popping up on Amazon, but I stopped because it was expensive. I accidentally popped a Rasp pi. That's right, let's make a PBX. Answering machines are also included in Asterisk, and since my home is a Hikari Denwa, I should be able to connect easily. It should be possible with simple settings and IVR scripts.

IP-PBX is a telephone exchange that builds a LAN network with a telephone and enables calls using the Internet.

IVR (Interactive Voice Response) is a system that distributes correspondence to communicators by voice guidance prepared in advance and number input according to the reason for incoming call.

Make a fraudulent phone call with your Raspberry pi.

Asterisk (PBX) is a telephone line switchboard that controls the connection of extension telephones. In addition to connecting extensions, it also controls what goes from the outside to the extension and what goes from the inside to the outside. Use this feature to let the Raspberry PI speak.

Prerequisites

--It has been converted to an optical telephone (IP telephone). --You have a contract for number notification. --You have a home internet contract.

The parent device of the phone is Raspberry pi, and the child device is a family smartphone!

Smartphone preparation

Install your favorite sip ip-phone.

Download Please install it on your mobile phone.

It's easy to set up.

Hikari Denwa settings on the router

First, connect your iPhone to extension number 3 for testing.

Please call the mail order site starting with 0120 for a trial.
