VoIP systems, like any internet-connected technology, require proper security measures. Here are the essential practices to keep your business communications safe.
Encryption Is Non-Negotiable
SRTP (Secure Real-time Transport Protocol) encrypts your voice calls end-to-end. TLS secures signaling. WOCOM uses both by default on all connections.
Strong Passwords and Access Control
Use strong, unique passwords for every extension. Enable two-factor authentication for admin access. Limit access to the PBX management interface to authorized IPs only.
Firewall Configuration
Configure your firewall to only allow SIP traffic from known IP ranges. Block international calling destinations you don't need. Monitor for unusual call patterns.
Regular Updates
Keep your IP phones and PBX software updated. Security patches address newly discovered vulnerabilities.
