📄️ Commercial certificate
This guide installs a certificate purchased from a commercial certificate authority (CA) for FreeSWITCH SIP-TLS and secure WebSockets (WSS). It does not replace the certificate used by Nginx for the FS PBX web interface.
📄️ Let's Encrypt certificate
FS PBX can issue, install, renew, and distribute a Let's Encrypt certificate for FreeSWITCH SIP-TLS and secure WebSockets (WSS). It can also create a self-signed certificate when a publicly trusted certificate is not required.
