7. Bandwidth - Audio Lync to Lync calling • These are raw audio codec bandwidth numbers – not for planning! • All numbers in Kbps. Based on 20ms ptime. Siren & G.722 include SRTP overheard from conferencing scenarios.

8. Bandwidth - Video Lync to Lync calling • These are raw video codec bandwidth numbers – not for planning! • FEC is already built into the payload bitrate • Maximum payload is the best possible frame rate & quality. • Minimum is approximately 1 video frame per second. • All numbers in Kbps. Based on 20ms ptime.

9. Bandwidth - Planning Lync to Lync calling For planning in a well managed, right-sized network, use Max BW w/o FEC. If the network will be constrained and you want to preserve quality, use Max BW with FEC. When understanding how much bandwidth at any given time is being used, use the Typical BW numbers. Not for planning, as usage will be greater at times. One-way traffic including media, typical activity, RTCP.

10. Bandwidth - Application Sharing Lync to Lync calling • Bandwidth used by application sharing is highly dependent on session content & screen resolution • TCP based sessions with built-in congestion control • Traffic is bursty in nature - Zero in ‘steady state’, spikes on transitions • End user policy limits available to cap spikes

11. Audio/Video Bandwidth Controls Lync to Lync calling • End User maximum allowedbandwidth per modality • Applied whether or not bandwidth is available • Configured via in-band provisioning at sign-in Client AVMCU

20. Lync to PSTN calling Lync to Phone calling Emergency & Location Awareness Emergency Dialing with Location Malicious Call Tracing Location-based Number Translation • Available in Lync, Lync Phone Edition & Attendant Console. • Tagging is reflected in the backend CDR database, enabling the Lync Server administrator to take action on the call.

21. Lync to PSTN calling Emergency Dialing and Locations • Each network region can define a location • Unique emergency dial strings & dial mask defined in the location policy for that network region • Policy contains PSTN Usage, directing emergency calls to the PSTN Gateway in that site & out to the local emergency services.  • If that same user was in Spain, the different network would apply a different location policy & PSTN usage, directing emergency calls to the local Spain gateway. • Core capability exists independent of location-based E911

25. Call Park Enterprise Calling Features • Parking clients:Lync, Attendant, Phone Edition • Retrieving clients: Above plus OCS 2007 R2Clients, Common Area Phones, PBX Phones, etc. • Orbit Range • Call Park uses orbits for parking calls - internal numbers not assigned to users • Orbits are scoped at the pool level by assigning the range to the Call Park Service running • Have enough orbits so that any one orbit is not reused too quickly • Comparison/Caveats • No assigning DID numbers as orbit numbers • No need to define an orbit range for every pool but must disable call park service on pools without defined ranges • No pickup possible from any ringing extension

26. Private Line Enterprise Calling Features • Single SIP URI, single Exchange mailbox, single presence source • Receipt of inbound calls on private DID to same SIP URI • Private lines carry many of the same features • Call pickup & park work as expected • Simultaneous ringing & call deflection on primary line carry to private line • Private lines are different: • Available for inbound calls only • Overrides delegation, call forwarding, do-not-disturb and other routing options – private calls are always going to go through • Calls to a private line have a distinctive ring & “toast” pop-up

39. DSCPExample “Fully Managed” Network Deployment On Site Networking More info @ Cisco Implementing Quality of Service Policies with DSCP

40. Media Port Separation On Site Networking • On the client, unique DSCP marking requiresnon-overlapping port ranges • If the client isn’t trusted, separate ranges & mark packets at the router • Configure separate port ranges: audio, video, sharing, & file transfer • Use same port range for audio on AVMCU, Mediation, Conferencing Auto Attendant (CAA), PVA, Response Group Service (RGS), Call Park • Use separate port range for video on AV Conferencing Server • Use separate port range for app sharing on AS Conferencing Server • Make Client audio/video port ranges subset of Server port range • E.g. Server audio port range = 49,152 – 57,500 • Client audio port range = 57,480 – 57,500

41. Session Resiliency On Site Networking • Signaling and media are separate sessions • Signaling TCP • Media UDP or TCP • Session resiliency and recovery allows media to continue in the event of disruption of the signaling session • Stateful Layer 3 Middleboxes (e.g. Load Balancers) resetting TCP connections • Intermediate signaling proxies failing over (e.g. emergency patching) • During loss of signaling channel endpoint enter resiliency mode • Some loss of functionality, e.g. hold/resume, conference roster, etc. • Media session will continue • Automatic recovery of signaling channel whenever possible

42. Call Admission Control On Site Networking • WAN link bandwidth policies • Applied dynamically when session crosses network link • Limits to maximum allowed level when bandwidth available • Re-routesor fails session when bandwidth not available • Policy Server role in Lync Server implements CAC • Admins configure logical sites based on groupings of subnets • Enforce policies on links between sites • Bandwidth available for audio, video • Seamless support for roaming users on moving between different sites • Allows Internet to be used for overflow of traffic • Avoid PSTN call charges • Support alternate path & failover of video sessions

47. Lync Telephony Deployment Replace the PBX “We’re sold – our goal is Enterprise Wide UC as soon as practical” Connect with the PBX “We love Lync, but I can’t replace everything yet….” Retain the PBX “Lync is our presence platform, but all telephony will remain on the PBX”

48. Lync Telephony Deployment Implications How What Replace the PBX SIP Trunking Lync Everywhere Gateway to PSTN Using Lync Voice where practical for the business Connect with the PBX Direct SIP to IP-PBX Gateway to TDM PBX More Costly with Suboptimal UEX Retain the PBX Separate Servers & Vendors for UC

49. SIP Trunking Replace the PBX Gateway to PSTN • PBX becomes obviated • Intra-company calls route through PSTN • Sensible for right combination of internal politics, Δ over time. • DIDs & Numbering • Move the numbers: Lots of carrier hassle • Get new numbers: Expensive at scale • SIP Trunking • Fastest way to future proof solution • Regional availability may be an issue • Gateway • Are scale & quantity of Mediation is a concern with SIP Trunking. • Consider deploying behind PBX’s Gateway

50. Direct SIP to IP-PBX Connect with the PBX Gateway to TDM PBX • Who moves? • Locations: Main site first, may make numbering easier. • Job functions: Those that can best prove out the ROI • Depreciation: Old equipment / stations go first, new ones later. • PBX stays resident • GW CapEx on may be disadvantageous if traffic peaks then falls • Does it make sense to reconfigure or replace the shop floor? Emergency campus phones? Garage phones? • Direct SIP • Available for most older IP-PBX releases   • Blocking interop to aid in compete against Lync.
