Why HTTPS Is Mandatory for VICIdial & VICIphone
Modern VICIdial deployments cannot function reliably on plain HTTP anymore. HTTPS is a technical requirement for browser compatibility, WebRTC (VICIphone), and user trust.

Why Modern Browsers Block HTTP Dialers
All major browsers flag HTTP sites as insecure, causing WebRTC permissions to be blocked, microphone access failures, and VICIphone initialization errors.
Why Self-Signed Certificates Fail
VICIphone requires a valid CA-signed certificate (Let's Encrypt via Certbot). Self-signed certificates break WebRTC security validation.
Prerequisites Before Installing SSL
Fully Qualified Domain Name (FQDN) Is Mandatory — SSL cannot be issued for a raw IP address. Required ports: 80 (HTTP validation), 443 (HTTPS), 8089 (WebRTC/WSS).
ViciBox Automated SSL Setup (Recommended)
On ViciBox, use vicibox-ssl or vicibox-certbot wizard. Enable SSL flags: a2enflag SSL then systemctl restart httpd.
Manual SSL Setup for Scratch Install (CentOS)
Install Certbot: yum install certbot. Stop Apache, generate certificate: certbot certonly --standalone -d yourdomain.com. Configure Apache SSL VirtualHost with paths: /etc/letsencrypt/live/yourdomain.com/fullchain.pem and privkey.pem.
ACMEv1 End-of-Life Risk (Critical Expert Gap)
Let's Encrypt retired ACMEv1. Old Certbot clients can no longer renew certificates. Upgrade Certbot or use ViciBox automation tools.
Asterisk & WebRTC Secure Integration (VICIphone Core)
Secure WebSockets (WSS) mandatory. Configure Asterisk http.conf TLS certificate paths and rtp.conf dtlscertfile. Ensure STUN server is functional. Port 8089 must be open.

Fixing Common VICIphone Errors After SSL
“Number Not in Service” — Fix: Set dialRegExten = 0.
ssl_error_rx_record_too_long — Enable SSL flag: a2enflag SSL and restart Apache.
No audio / one-way audio — Verify DTLS certificate path and STUN reachability.
Expired SSL — Automate renewal with Certbot cron job.

Updating Call Recording Links to HTTPS
Add --HTTPS flag to AST_CRON_audio_2_compress.pl script and update crontab entries.
Automating Let's Encrypt Renewals
Set up cron job: 0 3 * * * certbot renew --quiet --post-hook "systemctl restart httpd".
Verification & Diagnostics
- Browser Test: No security warnings, certificate trusted.
- Apache SSL:
systemctl restart httpd, port 443 active. - Asterisk TLS:
asterisk -rx "http show status" - WSS Operation: Browser dev tools show wss:// connections.
- DTLS Validation: Two-way audio confirms DTLS works.

Security Best Practices
Always use trusted CA certificates, enforce WSS, monitor renewal logs, restrict firewall to minimal ports (80,443,8089), protect recording directories with HTTPS.
Final Recommendations
Implement core improvements, create a 30-60-90 day roadmap, assign responsibilities, monitor weekly.
