How does 3CX ensure security in the audio stream of calls?

3CX ensures security in the audio stream of calls primarily through the use of encryption protocols. These protocols encrypt the audio data being transmitted during a call, ensuring that the communication remains confidential and cannot be intercepted by unauthorized parties. By applying encryption techniques such as SRTP (Secure Real-Time Transport Protocol), 3CX safeguards the integrity and privacy of voice communications, making it much harder for potential eavesdroppers to decode or access the audio stream.

While limiting user access, regular software updates, and encrypting the entire network contribute to the overall security framework, they do not specifically address the security of the audio stream itself in the same direct manner that encryption protocols do. Limiting user access primarily deals with who can access the system and its features, regular software updates focus on patching vulnerabilities and improving overall performance, and encrypting an entire network involves securing all data traffic rather than specifically targeting the audio portion of calls.
