  1. John Lamb Modality Systems Ltd People at the Centre of Unified Communications

  2. The Issue

  3. Info-Mania • University of London Study (2005) found: • The relentless influx of emails, mobile phone calls and instant messages received by information workers can reduce their IQ by 10 points • Working amid a barrage of incoming information can reduce a person's ability to focus as much as losing a night's sleep. • men were twice as vulnerable to distractions as women.

  4. The Solution Presence

  5. ScenariosExchange 2007 Unified Messaging

  6. ScenariosPC2Phone & Phone2PC

  7. Phone2PC The problem today

  8. The Iceberg • Do you need a Quality of Service (QoS) network? • Network Equipment vendors say yes... obviously • Microsoft says focus on Quality of Experience - let the codecs handle the problems

  9. QoS vs. QoE • “Network” Effects • Delay / RTT • Jitter • Loss • “Non-Network” Effects • Gain • Noise • Echo • Devices • Adaptive and intelligent codecs can address the non-network effects....

  10. Network Requirements • Reality is that you need to care about the network • Weigh the Cost of QoS vs. Cost of giving your applications the network they need. • Plan for throughput • 44 kbps per voice call • 300 kbps per video call • These numbers are “worst” case – what you need for the highest level of experience. • Look for delay • One-way delay over 150 ms is bad

  11. Deployment: One Step at A Time • Start with Exchange 2007 UM • This is available today • Well-defined, prescriptive guidance • Established partner base / expertise • Deploy LCS 2005 for IM and Presence • This is available today • ROI is immediate (even if not easily measurable)

  12. Deployment: Next Steps • Deploy LCS/OCS Remote-Call Control • Extends life of your existing PBX • Well-defined, prescriptive guidance • No rip-and-replace required • Start thinking about OCS 2007 voice for teams • Deploy UC voice to hotdesks, or IT department • Keep critical voice service on existing voice infrastructure (elevator fire alarms, etc)

  13. Deployment Tips • Telecoms vs. Networks vs. Applications • Avoid turf wars • Pre-wire decision making meetings • Get “skin in the game” from vendors • Exchange/LCS/AD Admin does not have to become a telecoms geek overnight (or ever) • Don’t underestimate “numbering” complexity • Phone number assignment and number normalisation is complex • Requires coordination / synchronisation across directories to succeed.

  14. Thank You! Q & A
