Describes this Media Crypto Profile so that it is easily identifiable.

Operation Option

  • Required
  • Supported
  • Off




Specifies how encryption is supported for this profile.

  • Required - This setting permits call connections only if security (encryption) can be used for the call. If the peer device does not support SRTP (Secure Real Time Protocol) for voice encryption over the IP network, call setup will fail.
  • Supported - This setting advertises to the peer device that the UX implements SRTP. However, a call connection is allowed in secure or unsecure mode depending on the peer preference and capability.
  • Off - This setting disables the use of SRTP for encrypted calling.

Crypto Suite

  • AES_CM_128_HMAC_SHA1_80
  • AES_CM_128_HMAC_SHA1_32




This setting lets you configure the crypto suite that the UX should use to negotiate with its peer device.
