  5. SIP – The Glue • SIP is to VoIP what SMTP is to email and HTTP to the Internet • The Session Initiation Protocol (SIP): • Open peer-to-peer signaling protocol used for establishing sessions in an IP network • Defacto standard for VoIP • A session could be a simple two-way phone call, data exchange, or a collaborative multimedia conference • A SIP server and client have complete control over their session (voice, video, conference, Instant Messaging, etc.) • This is unlike traditional telecom systems, where services are controlled by a central switching element

  6. SIP – A Bit More • Unique opportunities for innovative services • Service providers are creating new revenue-generating opportunities by bridging voice and data • Open APIs • 3rd Party development model  verticals, custom apps • Strong instant messaging & presence capability • Windows XP supports SIP • Mobile phone companies are doing SIP development • SIP is an RFC from the Internet Engineering Task Force (IETF), the global Internet standards body • Mitel is an active SIP Forum member • Mitel is hosting next SIPit, an industry interop event

  7. Multimedia SIP Devices • Hard Phones: wired, wireless, GSM • Softphones: Windows XP, SIP Softphone • PCs, servers, PBX’s, Media servers • PDAs • Collaboration, Unified Messaging, Instant Messaging • Video-conferencing

  9. Issues Affecting Voice Quality • Solving the top five voice quality issues: • Jitter buffer • Error interpolation & concealment • Traffic shaping & routing • Codecs: G.711, G.729, G.722.2, moving to wideband • Echo canceling • And now you want to measure this: • PESQ, MOS score on a VoIP network • Compared to cellular • Compared to toll quality Bottom line for a user: it just has to sound GREAT
