srtpCipher
The SRTP cipher suite negotiated for this transport.
Description
String
The descriptive name of the SRTP protection profile negotiated for the DTLS transport, as defined in the "Profile" column of the IANA DTLS-SRTP protection profile registry. This value is only present when dtlsState is "connected", since the SRTP profile is negotiated during the DTLS handshake.

Notes
- Typically "SRTP_AES128_CM_HMAC_SHA1_80" or "SRTP_AEAD_AES_128_GCM"
- This cipher protects the actual media (audio/video) after the DTLS handshake completes
