What is FreePBX?

FreePBX is a web-based open source GUI that controls and manages Asterisk. We cannot use the FreePBX inside our Web app. We have to use this in a separate domain. We can access the call history and recordings from our app.

System Requirements

1. Server with Linux OS
2. Registered Domain Name with installed TLS(“Let’s Encrypt”) certificate.
3. SIP account to make the outbound calls.
