According to its website, Ngrok is a way to “expose local servers behind NATs and firewalls to the public internet over secure tunnels” which is how we connect the Pi server to Twilio services in two steps after downloading and installing Ngrok on the Pi.

Twilio is a low-cost cloud service that provides APIs that add communication services to applications. We bought our phone number, which costs $1.00 per month, even if we don’t use for any calls or messages. Twilio charges $0.085 a minute for incoming calls and $0.013 a minute for outgoing calls. Sending or receiving a text message from our Twilio number costs $0.0075, while recording a voicemail is only $0.0025. Even if we receive 100 messages a month, the cost of those, plus the phone number, is only two or three dollars. To increase the security of this task, it might be a good idea to consider a proxy server from companies similar to fineproxy. The last thing you’d want is to get hacked! But I digress.
