location and enhanced 911
Location and Enhanced 911
  • Uses LIS (Location Information Server )
  • Location used for Presence, Emergency Routing, or both
  • LIS database Contains):
    • Wireless Access Point (BSSID)
    • LLDP Port
    • LLDP Switch
    • Subnet
    • MAC
  • Location Policy used for E911 and routing
    • User
    • Subnet
  • E911 provided through Emergency Service Provider
    • Include Security Desk IM and conference
  • Outside United States; use location based emergency routing
voice routing trunk translations
Voice Routing – Trunk Translations
  • Centrally manage number formatting prior to routing to PBX/PSTN
  • Alice calls London using Redmond +44221234567  01144221234567
  • Alice calls London using London GW+44221234567  0221234567
caller id presentation controls
Caller ID Presentation Controls
  • Natively control Caller ID presented to PSTN/PBX:
    • Granular controls based on callers and destination number:
    • Alice to external PSTN number, +1 425 707 9050  +1 425 882 8080
    • Alice to internal PBX number, +1 425 707 9050  +1 425 707 9050
    • Controlled by PSTN usage
    • Overrides “simultaneous ringing”:
      • Bob calls Alice; Bob has masking for external calls & also has simultaneous ringing
      • Bob’s caller-id is presented to Alice’s mobile device
exchange unified messaging um
Exchange Unified Messaging (UM)
  • The Only supported voice mail solution
  • Support for Exchange UM 2007 SP1 and newer
  • Co-locate UM and Mailbox servers
    • MAPI traffic is less tolerant of latency than VoIP in this scenario
  • UM and Lync in separate forests is supported
    • Just ensure the EUM settings in the user objects are synched to Lync forest
  • Exchange Online and OnPrem together?
    • Yes
    • Turn on EUM enablement setting on the user object
      • User Move
      • LyncPowershell
    • Edge Server is required to be deployed
and much more
And much more…
  • Response Group Service
  • Call Park Service

Deployment Model
  • Global Deployment is a collection of Sites
    • Sites are made of Pools
    • Pools host users & services (such as conferencing, Voice over Internet Protocol (VoIP))

Branch Office Site

Central Site

Sites that do not host a pool

Sites which host a pool of either SE or EE

  • Branches without redundant WANs will purchase a Survivable Branch Appliance to handle voice resiliency in the branch office
  • Branches with a redundant WAN connection, still require basic PSTN termination with SIP Gateway.
  • Standard Edition Server can be utilized for improved Quality of Experience (QoE) in large, distant “branches” (truly a Central Site) with lots of conferencing utilization.
  • Not all branches will require resiliency – for smaller branches, use Remote User Connectivity over public internet or 3G/4G network.
  • Smaller organizations not requiring resiliency can choose a Standard Edition Server (SE), a single server with all roles consolidated on that server functioning
  • Organizations who need resiliency will choose an Enterprise Edition Pool (EE), defining a pool of multiple servers comprised of front end and back end roles
  • “Paired” Standard Edition can offer failover between two SE servers for lower cost and reduced functionality.
  • Additional Server roles required include Archiving, Director, Edge and Monitoring

  • Interoperability via Direct SIP (OIP qualification)
    • Very broad range of PSTN gateways, Direct SIP to IP-PBX
  • R2 Direct SIP requires routing media through Mediation Server
    • Not a significant problem for central sites
    • But difficult in branches:
      • Requires Mediation Servers in branches and/or
      • Media tromboning (hairpin through the WAN to Mediation Server in central site)

Lync 2010: Media Bypass

  • Removes need for media transit
    • Signaling continues to transit through Mediation
      • B2BUA: security demarc, interop…
    • Media goes direct
      • 3 Advantages + media resiliency
  • Based on location of Media endpoints
    • Bypass only occurs if client is “local” to next hop
      • G.711 direct – optimized for LAN-like conditions; SRTP supported
    • When client is not “local”, media goes through Mediation
      • Codec optimized for WAN using per session CAC;
      • Mediation provides audio healing
  • Enables “lightweight” Mediation (collocation with FE, SBA)

Lync 2010: Media Bypass

How it works – two approaches

  • “Always Bypass” in “Global Settings”
    • Treats as a single site ( requires good connectivity )
    • No Call Admission Control
    • Will always bypass to trunks enabled for bypass
  • Network Configuration Setting
    • Leverages Region/Sites definition
      • Each site/Region is assigned Bypass ID
    • Uses current client location
      • Client IP address  Bypass ID
      • Gateway address (for media)  Bypass ID
    • Comparison of the IDs, bypass if the two IDs match
slide27

Lync 2010: Media Bypass

How it works – two approaches

slide28

Lync 2010: Media Bypass

Inbound and Outbound logic

  • Inbound calls
    • Mediation receives SIP invite; IP address of media gateway in SDP
    • Mediation passes gateway Bypass ID to clients
    • Client makes bypass decision
  • Outbound calls
    • Client passes Bypass ID in SIP Invite
    • Mediation determines gateway Bypass ID
    • Mediation Server compares, call is bypassed if matches
slide29

Testing and Qualification for Lync Interop

Open Interoperability Program – tested or in process of testing

  • Survivable Branch Appliances qualified, all support bypass
    • 5 partners – Audiocodes, Dialogic, Ferrari, HP, NET
  • Gateways (not all support bypass – see OIP page)
    • Cisco ISR series 28xx, 29xx, 38xx, and 39xx
    • Avaya 23xx and 41xx
    • Gateways from Media5, Nuera, and Quintum
  • IP-PBX (not all support bypass – see OIP page)
    • Cisco 4.x, Cisco 6.1, Cisco 7.1 and Cisco 8.x
    • Avaya CM/Aura 4.x, Avaya CM/Aura 5.x
    • Avaya CS1k 5.x, Avaya CS1k 6.x
    • Alcatel Lucent 9.x, Siemens 3.1Rx
    • Mitel, Genband, Aastra, and Huawei

Media Bypass – Multiple Sites, Centralized Signaling

What’s different

  • Centralized IP-PBX with multiple sites
    • Local media gateways in branch sites (ex: Cisco ISR with MTP)
      • Want to bypass media to local gateway when Lync is in the branch site
  • Media bypass in multiple sites?? How to --
    • Define regions and sites in network Configuration
    • Define (virtual) media gateways in topology builder
      • Associate media IP in site to each “media gateway”
      • Define listening ports as appropriate
    • Establish appropriate routing on both systems
      • IP-PBX unaware of Lync dynamic location; suggest routing to local trunk

Planning Cheat Sheet

  • Define Topology with CUCM and ISR
  • Use ISR as gateway by CUCM and Lync
      • Use it for PSTN calls by both “PBX”
      • Configure ISR for Media Bypass
  • Direct SIP between CUCM and Lync
      • Configure it for extension calls by both “PBX”
      • Including media bypass to CUCM
  • Migrate users stepwise

Virtually no additional Hardware required

takeaway
Takeaway
  • Integrating natively with IP-PBXs can
    • Allow low cost Proof of Concept
    • Connect migrated & non-migrated users
    • Allow for long term coexistence
  • Native integration with media bypass enables
    • CPE-less deployment
    • Keeping much more of the media local, including in centralized multisite topologies

It is possible!!
