System and method for classification of media in VoIP sessions with RTP source profiling/tagging
System and method to transmit an identification of a real-time transport protocol (RTP) data stream, the method including: identifying an identification of an RTP data stream; inserting the identification of the RTP data stream into an RTP header extension; and transmitting, by use of a network interface, an RTP packet comprising the RTP header extension. The method may further include: consulting a policy for profile tag settings, wherein the step of inserting the identification is dependent upon the policy.
1. A method to transmit an identification of a real-time transport protocol (RTP) data stream, comprising:
identifying a present identification of a profile tag of a source of an RTP data stream;
detecting a change from a previous identification of the profile tag of the source of the RTP data stream to the present identification of the profile tag of the source of the RTP data stream;
if said change is detected, perform the step of: consulting a policy for source profile tag settings;
inserting the identification of the profile tag of the source of the RTP data stream into an RTP header extension; and
transmitting, by use of a network interface, an RTP packet comprising the RTP header extension;
wherein a playback characteristic of the RTP data stream is modifiable based upon the change in the identification of the profile tag of the source of the RTP data stream in the RTP header extension.
2. The method of claim 1 , wherein the step of inserting the identification is dependent upon the policy.
3. The method of claim 1 , wherein the identification comprises a source of the RTP data stream.
4. The method of claim 1 , wherein the identification comprises a profile tag of the RTP data stream.
5. The method of claim 1 , wherein the identification comprises a name of the RTP data stream.
6. The method of claim 1 , wherein the identification comprises a priority of the RTP data stream.
7. A method to modify a playback characteristic of a real-time transport protocol (RTP) data stream, comprising:
receiving, by use of a network interface, an RTP data stream comprising an RTP header extension;
identifying a characteristic of the RTP data stream from the RTP header extension, wherein the characteristic comprises a profile tag of a source of the RTP data stream;
consulting a policy for source profile tag setting to determine a modification of the playback characteristic;
modifying the playback characteristic based upon an identification of the characteristic of the RTP data stream, wherein modifying the playback characteristic further comprises modifying the playback characteristic based upon a change in the identification of the source of the RTP data stream.
8. The method of claim 7 , wherein the step of modifying the playback characteristic comprises lowering a volume level if a source of the RTP data stream comprises a music server.
9. The method of claim 7 , wherein the step of modifying the playback characteristic comprises lowering a volume level if a source of the RTP data stream comprises a recorded message.
10. The method of claim 7 , wherein the step of modifying the playback characteristic comprises substantially maintaining a lowered volume level if a source of the RTP data stream comprises a recorded message.
11. The method of claim 7 , wherein the step of modifying the playback characteristic comprises raising a volume level if a source of the RTP data stream comprises a voice bridge of a conference server.
12. The method of claim 7 , wherein the step of modifying the playback characteristic comprises modifying a playback quality of the RTP data stream.
13. The method of claim 7 , further comprising:
presenting to a user the identification of the source of the RTP data stream; and
obtaining user permission before modifying the playback characteristic.
14. The method of claim 7 , wherein the step of modifying the playback characteristic further comprises: presenting a user indication of a modified playback characteristic.
15. A system to transmit an identification of a real-time transport protocol (RTP) data stream, comprising:
an identification module configured to identify a present identification of a profile tag of a source of an RTP data stream;
a detection module configured to detect a change from a previous identification of the profile tag of a source of the RTP data stream to the present identification of a profile tag of a source of the RTP data stream;
a processor configured to consult a policy for source profile tag settings if said change is detected;
an insertion module configured to insert the identification of the profile tag of the source of the RTP data stream into an RTP header extension; and
a network interface configured to transmit an RTP packet comprising the RTP header extension;
wherein a playback characteristic of the RTP data stream is modifiable based upon the change in the identification of the profile tag of the source of the RTP data stream in the RTP header extension.
16. The system of claim 15 , wherein the processor is configured to insert the identification depending upon the policy.
