    10. Product Review and Roadmap Questions

    11. Network Topology

    12. Network Components Call Manager Is a VoIP server that receives calls or initiation requests from the PSTN or web Is an inter-networking system that connects two Networks together Gateway Is a Layer 2 device that uses MAC Addresses to decide where to forward the packets Switch

    13. Ai-Logix Network Components An external passive tapping device connected to the Network and IPX(tap box) TX100 Board for passive VoIP monitoring of packets, filtering data and forwarding media IPX Board that receives media packets that is capable of transcoding, summation and recording to a file IPM 260

    14. Where you TAP matters • Configurations vary from site to site • Even if it is the same product • Follow the path of the call • Tap point must be in the call flow • Mirror Port (Span Port) • Can help in some cases but are not always needed • Peer to Peer • May require additional tap points

    15. Basic Configuration

    16. Basic Configuration

    17. Basic Configuration

    18. Basic Configuration

    19. Network Signaling Centralized Call Logger

    20. External Data Logging Tapping External Traffic on Switch

    21. ExternalCall Recording

    22. Recording utilizing Span Port Peer to Peer Tapping

    23. Recording utilizing Span Port Peer to Peer Tapping Peer to Peer Call ( same workgroup) RTP packets To phones (RX)

    24. Recording utilizing Span Port Peer to Peer Tapping External Call RTP packets from phones (TX) to gateway

    25. Recording utilizing Span Port Peer to Peer Tapping External Call Both directions

    26. Limitations of Span Port • Bandwidth is limited to 100 Mb • Data may be lost if the traffic exceeds 100Mb (due to Span port limitations) • Example: monitoring multiple phones on a Span port

    27. Topology and Tapping Questions

    28. IPX Application Development

    29. Topics for Discussion • Overview of the IPX features • Presentation of the IPX Logical Card Model • Sample IPX Application

    30. IPX Features • Near real-time passive network monitoring • Filtering of non-VoIP related packets • Decoding of signaling protocols • RTP media session reporting • RTP media forwarding to a network voice processor

    31. Three 10/100 Ethernet ports Packet Redirection (Filtering) Session Manager Station Manager Passive Protocol Stacks RTP Media Forwarding IPX Logical Card Model

    32. Three Ethernet Ports • Two ports in promiscuous mode. • One receives upstream (TX) packets • One receives downstream (RX) packets • Configuration Optional • One port in “active” mode • Transmits RTP packets • Must be configured • All ports are configurable • IP Address • Subnet Mask • Default Gateway

    33. Packet Redirection (Filtering) Packet filtering is the selective passing or blocking of packets as they move through the network. • Filters all VoIP related packets and forwards to on-board resources: • Signaling Protocol Stack • RTP RTP Forwarder • Others Discarded • Host PC performs no packet filtering

    34. Session Manager • Tracks all RTP media connections • Allocates a unique session (Session ID) for each RTP connection pair • Reports media session creation/deletion via SmartWorks events • Session IDs are returned to free pool when media session ends NOTE: The maximum number of sessions per board is 256.

    35. Station Manager • Dynamically identifies devices and adds stations on the IPX • Assigns a unique Station ID to each device • Protocol ID + Station Number • Station IDs are not unique across multiple boards. • Reports station added/removed via SmartWorks events • Station IDs are returned to free pool when a station is removed NOTE: The maximum number of stations per board is 120.

    36. Passive Protocol Stacks The IPX abstracts the various VoIP protocols and provides a consistent interface to the user application. • Terminal Control decoding similar to the SmartWorks NGX D-Channel • Message-to-event translation • Messages reported to application via SmartWorks events • Call Control decoding reports changes in call state similar to the SmartWorks DP • Message-to-CC event translation

    37. RTP Media Forwarding • Forwards the media stream, associated with a Session ID, to a network device • User controls forwarding dynamically as sessions are created and destroyed • User supplies destination information • IP Addresses • UDP port numbers • Forwarding stops when the session stops

    38. New SmartWorks APIs for IPX • Configuration • Adapter, Signaling Protocol • Status and Control • Signaling Protocol, Media Session, Station • Statistics • Signaling Protocol, Station, Network Interface Note: SmartWorks release 3.3.1 was extended to support the IPX

    39. Event Reporting The IPX includes the StationID in the XtraInfo field of the event structure for all D-Channel, CC, Station and Media session events. • Station Events • Session Events • Call Control Events EVT_STATION_ADDEDEVT_STATION_REMOVED DATA: StationID, TCP Port, UDP Port EVT_MEDIA_SESSION_STARTEDEVT_MEDIA_SESSION_STOPPED DATA: SessionID, StationID, Caller IP Addr & UDP, & Callee IP Addr & UDP EVT_CC_CALL_ALERTINGEVT_CC_CALL_CONNECTEDEVT_CC_CALL_RELEASEDEVT_CC_CALL_SUSPENDEDEVT_CC_CALL_RESUMEDEVT_CC_CALL_HELDEVT_CC_CALL_RETRIEVEDEVT_CC_CALL_ABANDONEDEVT_CC_CALL_REJECTED DATA: MT_CALL_INFO structure

    40. SmartControl Accepts: • IP Address • Subnet mask • Default gateway • Interface 0: • Active Port • Forwarding • Interface 1: • Passive Port Interface 2: • Passive Port

    41. Things to Consider The IPX: • has no channels (no channel events) • all events arrive on the board queue • does not support the H.100 bus • does not have in-band detectors VoIP: • no dedicated circuits • semi-intelligent terminals
