What is VoIP encryption?

VoIP encryption is the process of securing voice data as it travels over the internet, making it unreadable to unauthorized users. It uses VoIP encryption protocols like TLS and SRTP to prevent eavesdropping, hacking, and data tampering.

SIP (Session Initiation Protocol) is the technology that sets up, manages, and terminates VoIP calls. However, it wasn’t designed with security in mind, which is why SIP TLS encryption is needed to protect call setup details.

How does TLS protect VoIP calls?

TLS (Transport Layer Security) encrypts SIP traffic, ensuring that hackers can’t see or manipulate call setup details. It prevents call hijacking and ensures that metadata remains private.

What is SRTP and why is it important?

SRTP (Secure Real-Time Transport Protocol) encrypts the actual voice data in VoIP calls. Even if someone intercepts the call, SRTP ensures they can’t decipher the conversation.

Does HIPAA require VoIP encryption?

While HIPAA doesn’t specifically demand VoIP encryption protocols, it does require healthcare providers to protect patient information in electronic communications. Using an encrypted VoIP phone with TLS and SRTP is highly recommended for compliance.
