IDENTIFY A SECURE END-TO-END VOICE CALL
First Claim
1. A method comprising:
- generating a Secure Real-Time Transport Protocol (SRTP) encapsulated packet;
including a secure media indicator into the SRTP encapsulated packet;
inserting the SRTP encapsulated packet into an SRTP voice stream associated with an active call between a source and a destination endpoint;
indicating an end-to-end secure call between the source and destination endpoints responsive to the secure media indicator.

Abstract
We describe a system embodiment comprising generating a Secure Real-Time Transport Protocol (SRTP) encapsulated packet and including a secure media indicator into the SRTP encapsulated packet. The method further comprises inserting the SRTP encapsulated packet into an SRTP voice stream associated with an active call between a source and a destination endpoint and indicating an end-to-end secure call between the source and destination endpoints responsive to the secure media indicator.
And we describe a method embodiment comprising transmitting a request message from a source endpoint to a destination endpoint participating in an active call and setting a secure media flag in the request message at each node in a signaling path associated with the active call. The method further comprises returning a response message from the destination endpoint to the source endpoint responsive to the request and indicating an end-to-end secure call between the two endpoints.

16. A method, comprising:
-
transmitting a request message from a source endpoint to a destination endpoint participating in an active call; setting a secure media flag in the request message at each node in a signaling path associated with the active call; returning a response message from the destination endpoint to the source endpoint responsive to receiving the request at the destination endpoint; indicating an end-to-end secure call between the source and destination endpoints along the signaling path of the active call responsive to the secure media flag. - View Dependent Claims (17, 18)

20. Software encoded in one or more computer-readable media and when executed operable to:
-
generate a Secure Real-Time Transport Protocol (SRTP) packet when a source endpoint is in a secure mode, the SRTP packet including a secure media indicator in its payload type; periodically insert the SRTP encapsulated packet into an SRTP voice packet stream associated with an active call between the source endpoint and a destination endpoint; and determine an end-to-end secure call between the source and destination endpoints responsive to the secure media indicator.
