2 What Does It Take To Play? Communications at the desktop What open standards do for YOU SIP is the multimedia standard that links it all together Devices that play in the SIP telephony market An idea of configurations Conclusions

4 Open Standards Customer Benefits Assumes use of IP (Internet Protocol), networks, Internet Scalable and futureproof Simplified communications network reduces system costs Delivers voice, , video and data to every desk Connects best of breed in multi-vendor environments Strengthens corporate culture inside distributed organizations with consistency across disparate systems Potential for new competitive business advantages

5 SIP – The Glue SIP is to VoIP what SMTP is to 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 3 rd 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, PBXs, Media servers PDAs Collaboration, Unified Messaging, Instant Messaging Video-conferencing

8 SIP Telephony

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
