Secure call indicator mechanism for enterprise networks
Abstract:
The concept of a secure call indicator is introduced. In general, the secure call indicator is capable of inspecting the security of signaling associated with Session Initiation Protocol (SIP) messages and comparing the security with media descriptions of the actual media path of the SIP messages. Furthermore, the secure call indicator may be configured to indicate the security associated with a communication session via a physical or virtual notification system.
