I am going to provide step by step guide to integrate, enable and configure the viciphone(a webrtc phone) in vicidial (also applicable to any vicidial based system) using the Self Signed SSL Certificate ,ie without a public-ip and FQDN or accessing the vicidial with internal LAN IP. 1️⃣ Install OpenSSL (if not installed) sudo dnf install -y openssl 2️⃣ Generate a Private Key openssl genpkey -algorithm RSA -out selfsigned.key -pkeyopt rsa_keygen_bits:2048 3️⃣ Create a Certificate Signing Request (CSR) openssl req -new -key selfsigned.key -out selfsigned.csr It will prompt you for details like: Country Name (e.g., IN ) State or Province (e.g., Gujarat ) Locality (City) Organization Name Common Name (Domain, e.g., example.com or your server IP) Email Address You can use localhost or an IP address if needed. 4️⃣ Generate a Self-Signed Certificate openssl x509 -req -days 365 -in selfsigned.csr -signkey selfsigned.key -out selfsigned.crt -days 365 → Valid for 1 year (Adjust as needed) ...
