Assign Let’s Encrypt Certificate to Asterisk (Core) SIP TLS.
How to Install let's encrypt certificate on asterisk (core) and assign to the SIP TLS?
Asterisk is an open-source communication tool kit. We can build voice, video, and text applications with it. Asterisk supports several standard VoIP (voice-over IP) protocols, including the SIP (Session Initiation Protocol), MGCP (Media Gateway Control Protocol), and H. 323. It supports most SIP telephones, acting both as registrar and back-to-back user agents.
Let's Encrypt is a free SSL certificate provider. We can use this certificate for the SIP TLS encryption in the asterisk. We need to install certbot in the system.
