SBC supports SRTP media pass-through for SRTP and SRTCP media streams. SBC does not terminate the SDP security description or SRTP media streams and passes them through without authenticating, decrypting, and encrypting. If Enable SRTP is enabled and Allow Passthru flag is also enabled, SBC treats SRTP media as plain text RTP pass-through media.

Update Crypto Keys On Modify

For an SRTP call, if this flag is enabled in Packet Service Profile and call leg mode is changed from sendonly/inactive/recvonly to sendrecv, the SBC generates a new set of crypto attributes. The options are:

  • Disable (default)
  • Enable
Allow Passthru

When this flag is enabled, it allows SBC to pass-through SRTP media without authenticating, decrypting, and encrypting it internally. When selected, this flag prioritizes SRTP pass-through media over terminated SRTP media.

When this flag is disabled, SBC terminates all SRTP and SRTCP media for authentication, encryption, or decryption.

Note

To configure this flag, SRTP must be enabled by enabling Enable SRTP flag.

The options are:

  • Disable (default)
  • Enable
