When you make calls over the internet, security controls, measures designed to protect voice data from interception, tampering, or unauthorized access. Also known as VoIP protection protocols, they’re not optional—they’re the difference between a clear business call and a data breach. Without them, your SIP trunks can be hijacked, attackers can drain your calling credits with toll fraud, or sensitive conversations get recorded by outsiders.
Good security controls, measures designed to protect voice data from interception, tampering, or unauthorized access. Also known as VoIP protection protocols, they’re not optional—they’re the difference between a clear business call and a data breach. don’t just mean passwords. They include call encryption, the process of scrambling voice data so only authorized devices can decode it. Also known as SRTP, it’s the backbone of secure VoIP, used by providers like 3CX and Zoom Phone to stop eavesdropping. They also mean SIP trunk security, how your VoIP connection to the provider is authenticated and locked down. Also known as SIP registration security, it stops hackers from pretending to be your phone system and making free long-distance calls. If you’re using auto-provisioning templates or remote phones, you’re exposing yourself to risks if these aren’t locked down.
Compliance isn’t just for big companies. If you handle patient data, financial info, or even just private client calls, VoIP compliance, following legal rules like HIPAA, CCPA, or PCI-DSS when storing or transmitting voice data. Also known as telecom regulations, it forces you to encrypt recordings, control who can access logs, and delete data after a set time. The posts here cover real cases—like how pharmacies avoid HIPAA fines, or how call recording storage rules changed in 2025. You’ll see how misconfigured echo cancellers or weak SIP registration can become backdoors, and how UDP vs TCP choices affect your attack surface.
Security isn’t a one-time setup. It’s about knowing what to check every month: Are your phones auto-updating? Is your provider using TLS for signaling? Are your remote workers using VPNs? The tools and guides below show you exactly how to fix gaps—not just theory, but step-by-step fixes from real systems like Cisco, Asterisk, and cloud platforms. You’ll learn what actually works, what doesn’t, and how to stop threats before they cost you money or reputation.
