Exinda statefully tracks the SIP call setup process and classifies call requests from the details available. Classification during initiation includes details in the form of Private Branch eXchange (PBX) extensions of caller and receiver, CODEC to be used for RTP voice data during conversation and network level data e.g., bytes transferred and data rates of voice data transmission.

Configuration Modes:

In VoIP, the digital signal processor (DSP) segments the voice signal into frames and stores them in voice packets. These voice packets are transported using IP in compliance with one of the specifications for transmitting multimedia (voice, video, fax and data) across a network: H.323 (ITU), MGCP (level 3, Bellcore, Cisco, Nortel), MEGACO/H.GCP (IETF), SIP (IETF), T.38 (ITU), SIGTRAN (IETF), Skinny (Cisco), etc. The only specification supported by Exinda at this stage is the Session Initiation Protocol (SIP). Hence only the voice calls made using SIP would be classified by Exinda.

Coders are used for efficient bandwidth utilization. Different coding techniques for telephony and voice packet are standardized by the ITU-T in its G-series recommendations: G.723.1, G.729, G.729A etc. The coder-decoder compression schemes (CODECs) are enabled for both ends of the connection and the conversation proceeds using Real-Time Transport Protocol/User Datagram Protocol/Internet Protocol (RTP/UDP/IP) as the protocol stack. Exinda VoIP monitoring is independent of the CODEC in use for encoding or decoding the voice data sent using RTP.

* Detailed (drill-down) SIP VoIP Call Monitoring
Under Monitor | Applications, where 'sip-rtp' appears, there is a link next to it called 'View Calls'. This will take you to a list of SIP VoIP calls registered going through the Exinda. From here you can see the top inbound and outbound callers and callees in terms of data transferred. Furthermore, if you click on the link for an individual extension in the list, calls made or received by the extension will be displayed.

* Realtime SIP VoIP call monitoring
In the Monitor | RealTime section, the caller and the callee extensions will be displayed next to SIP-RTP traffic if the Exinda has detected the SIP VoIP call specific details.
