VoIP Subscriber- and User-Aware Forwarding

It just got easier — and more efficient — to monitor voice- and video-over-IP (VOIP) sessions carried in Real-Time Transport Protocol (RTP) and managed by Session Initiation Protocol (SIP) signaling. It’s called the SIP/RTP Correlation application, and is a licensable and intelligent addition to the GigaSMART® engine that enables enterprises and service providers to monitor VoIP traffic.

Because it understands the stateful nature of the SIP protocol, the SIP/RTP Correlation application can match and pass an identified user’s SIP signaling and RTP media sessions to the appropriate analytics, performance and security subsystems. That’s a big help ensuring an accurate view of the session performance, the user’s quality of experience and secureness of the communication.

With the SIP/RTP Correlation application, service providers and enterprises can now intelligently forward VoIP sessions to specific tools by filtering on ranges of or specific user IDs, sampling just a percentage of media sessions and/or balancing the aggregate SIP and RTP sessions.

Benefits of the SIP/RTP Correlation Application:

• More efficient, effective tool processing throughput
• Improved analytics accuracy from reliable correlation of user sessions
• Enables improved user experiences and service monetization with more accurate end-user quality of experience metrics
• More reliable accounting, billing and subscription management
• Fewer errors through accurate correlation of subscriber or user data fragmented in transit
