What is the function of SRTP regarding SIP traffic?

The function of SRTP (Secure Real-time Transport Protocol) in the context of SIP (Session Initiation Protocol) traffic is primarily focused on enhancing security through encryption. By encrypting the media streams associated with SIP calls, SRTP effectively prevents eavesdropping and protects the confidentiality of the communication. This is particularly important in environments where sensitive information may be transmitted, ensuring that unauthorized parties cannot intercept or listen in on the call.

While there are other protocols and methods in SIP that may monitor or manage traffic, they do not align with the primary objective of SRTP, which is to secure the media being exchanged. Therefore, the core purpose of SRTP is to safeguard the integrity and privacy of the communication through encryption, making it an essential component in securing voice over IP (VoIP) and similar applications.
