System and method for classification of media in VoIP sessions with RTP source profiling/tagging
System and method to perform a directive by a first SIP User Agent (UA) engaged in a peer-to-peer communication session with a second SIP User Agent (UA), the method including: arming the first SIP User Agent (UA) to define the directive; setting a trigger condition in the first SIP User Agent (UA) to perform the directive if the trigger condition becomes true; monitoring, by use of a processor within the first SIP User Agent (UA), for the trigger condition in the communication session; and if the trigger condition becomes true, performing by use of a processor the directive without usage of a back-to-back user agent.
1. A method to perform a directive by a first SIP User Agent (UA) engaged in a peer-to-peer communication session with a second SIP User Agent (UA), comprising:
arming the first SIP User Agent (UA) to define the directive;
setting a trigger condition in the first SIP User Agent (UA) to perform the directive if the trigger condition becomes true;
monitoring, by use of a processor within the first SIP User Agent (UA), for the trigger condition in the communication session; and
if the trigger condition becomes true, performing by use of a processor the directive without usage of a back-to-back user agent.
2. The method of claim 1 , wherein the steps of arming the first SIP User Agent (UA) and setting the trigger condition are by use of one or more out-of-dialog REFER messages.
3. The method of claim 1 , wherein the trigger condition comprises a signaling condition.
4. The method of claim 3 , wherein the signaling condition comprises one or more of setting up a call, tearing down a call and detection of a user command.
5. The method of claim 3 , wherein the signaling condition comprises detection of a predetermined SIP command.
6. The method of claim 1 , wherein the trigger condition comprises a billing condition.
7. The method of claim 1 , wherein the trigger condition comprises a time-based criterion.
8. The method of claim 1 , wherein the trigger condition comprises a characteristic of a media content of the communication session.
9. The method of claim 1 , wherein performing the directive comprises the step of invoking a SIP URL.
10. The method of claim 1 , wherein performing the directive comprises making at most one referral.
11. The method of claim 1 , wherein performing the directive comprises a step selected from a group of steps consisting of changing call state and creating one or more new calls.
12. The method of claim 1 , wherein performing the directive comprises assigning a lower priority to a second referral.
13. The method of claim 1 , further comprising the steps of:
monitoring, by first SIP User Agent (UA), a plurality of directives for a trigger condition; and
resolving, by the first SIP User Agent (UA), conflicts among the plurality of directives.
14. The method of claim 1 , wherein performing the directive comprises preserving media content and media connection information.
15. A system to perform a directive by a first SIP User Agent (UA) engaged in a peer-to-peer communication session with a second SIP User Agent (UA), comprising:
an arming module configured to arm the first SIP User Agent (UA) to define the directive;
a trigger, in the first SIP User Agent (UA), configured to perform the directive if a trigger condition becomes true;
a monitor configured to monitor for the trigger condition in the communication session; and
if the trigger condition becomes true, a processor configured to perform the directive without usage of a back-to-back user agent.
16. The system of claim 15 , wherein the arming module and trigger are configured to communicate via one or more out-of-dialog REFER messages.
17. The system of claim 15 , wherein the trigger condition comprises a signaling condition.
18. The system of claim 15 , wherein the trigger condition comprises a billing condition.
19. The system of claim 15 , wherein the trigger condition comprises a time-based criterion.
20. The system of claim 15 , wherein the trigger condition comprises a characteristic of a media content of the communication session.
21. The system of claim 15 , wherein the directive comprises at most one referral.
22. The system of claim 15 , wherein the directive comprises assigning a lower priority to a second referral.
23. The system of claim 15 , wherein the directive comprises preserving media content and media connection information.
