      • AEC (AES) – Acoustic Echo Concealment
      • Dynamic Jitter Buffer – has major effect on quality
      • Connection to sound card / microphone
      • DTMF
      • VAD, Mixer, AGC, NC (NS)
      • Voice quality monitoring
      • CODECs – G711, G729, G723.1, iLBC, GSM AMR (in mobile related applications)
  • 6.
    • Wideband codecs (8KHz VoIP)
      • GSM AMR WB – G722.1
      • iSAC 10-30KB
      • iPCM-WB – 80KB
      • Siren 7 – Polycom
    • UltraWideband Codecs (14KHz Voice)
      • Siren 14 – Polycom

    • <body>XMPP is easy!</body>
    • </message>
    • Numerous interoperable clients
    • Active Open Source and commercial ecosystem
    • Used by Google
  • 9.
    • Jingle
    • – Defines way for XMPP clients to exchange rich media.
    • – Audio is furthest along, but also work in progress for Video.
      • app sharing, etc.
      • Audio already in use by Google Talk .
    • – Makes it easy to work with SIP.
    • HTTP Binding
    • – XMPP over HTTP
      • – embed messaging and presence into any web page
      • with Javascript and Ajax.
    • – Possible Jingle integration for rich media in web pages? Perhaps using Flash ?
    • Personal Event PubSub (PEP)
    • – Share rich presence data like geo-location.

    • NAT and Firewall traversal are key components in most VoIP applications
      • Several NAT traversal protocols exists:
        • STUN – scalable partial solution
        • TURN – less scalable complete solution
        • ICE – uses STUN or Turn
      • Several techniques for Firewall traversal
        • Usage of TCP/IP lowers voice quality
