What is TLS and SRTP?
What is TLS/SRTP? Often TLS is used alongside Secure Real-time Transport Protocol (SRTP). TLS encrypts the signaling of the calls, which you can think of as the set up and tear down portion of a call, and SRTP secures the actual media – the little ‘packets’ of data that run over the highway set up by the signaling.

SRTP uses Advanced Encryption Standard (AES) as the default cipher. This includes two cipher modes: Segmented Integer Counter Mode and f8-mode. The NULL cipher does not perform any encryption, and instead operates as an identity function. It copies the input stream directly to the output stream without any changes.
