SPAN / RSPAN Methodology for Capture of RTP Traffic
VPI's recording methodology leverages SPAN ports or taps on network switches that monitor network traffic and/or sniff the network, then send the data to a destination port. VPI CAPTURE™ Aspect call recording software uses Span (or Local SPAN) when both the source ports (or source LVANs) and destination ports are on the same switch or switch stack. RSPAN ports can also be configured and utilized if needed - RSPAN supports source ports (or source LVANs) and destination ports on different switches or different switch stacks.

CMI Server Signaling – Recording Start/Stop Event
Precise definition and reception of events that direct the recording system to start or stop recording are vital for creation of recordings that contain the entire agent conversation from beginning to end. VPI's VPI CAPTURE™ Aspect recording system accepts these events from Aspect's CMI server, in addition to identification of the agent who makes or takes a call and collection of CTI based metadata. This metadata is stored in the recording system's database and associated with specific recordings, to facilitate precision search, playback, reporting and more.
