With the End-to-end secure call indication feature, a SIP phone displays the security icon , indicating the security of a SIP call.
The SIP phone displays the security icon when the end-to end call has the following setup:
  • Media is SRTP.
  • SIP signaling is TLS.
  • Media Server signaling links or Media Gateway links, if applicable, are TLS.
The security levels of SIP signaling coming from Session Manager are based on the Av-header.
The End-to-end secure call indication feature is applicable only for point-to-point calls. The icon on the SIP phone displays the call as secured only for two-party calls. However, when a third-party is involved, such as a conference, the icon displays the call as unsecured even if the call is on a secured network.
Session Manager uses a new header called Av-Secure-Indication to convey the end-to-end security of the call. For information about:
