What are the security measures in place to protect VoIP calls from eavesdropping and tampering?

To protect VoIP calls from eavesdropping and tampering, robust security measures such as encrypting voice data using protocols like Secure Real-time Transport Protocol (SRTP), implementing strong access controls, deploying intrusion detection and prevention systems, and using virtual private networks (VPNs) can safeguard against unauthorised access and potential attacks.

Additionally, leveraging firewalls and network security policies, ensuring regular software updates for VoIP equipment, and employing encryption key management techniques can further enhance the security of VoIP calls.

By prioritising these security measures, businesses can mitigate the risks of eavesdropping and tampering in their VoIP communications, ensuring confidentiality and integrity of sensitive conversations.
