Lync Geographic Presence Configuration RRS feed

  • Question

  • Hi,

    Global environment, where there is already a global IPT solution with gateways in place at each geographic location.  A customer wants to implement Lync for a subset of users across the Globe and yet operate a Central-Site Lync deployment.

    Question: Can the user still maintain their geographic calling identity using Lync in this scenario?  i.e. This is the process as I see it:

    - user resides in Country B, places a call using Lync

    - call crosses the WAN to Centralised Lync deployment at Country A

    - user's E164 number is the full Country B number format

    - Lync process the call via 'Per-User' Dial-Plans and routes the call to the centralised IPT gateway at Country A.

    - Centralised IPT gateway receives the call from Lync, knows source calling identity is Country B E164, and so sends the call out to the PSTN either via the local Country B IPT gateway or Country A's IPT gateway, whichever is cost-effective.

    Assuming the existing IPT solution can be configured to handle calls from Lync in this way, is it generally possible to maintain geographic calling identity using a centralised Lync Deployment in this way?

    Experienced comments welcomed!  Thank you.

  • Hi,

    What you mentioned above can be done using LYNC. Given that they have VPN connections with sufficient bandwidth for all the geographically separated locations.

    If you are looking at a centralized deployment consider having SBA (Survivable Branch Appliance) or SBS (Survivable Branch Server) in branch locations with Mediation Servers to optimize the deployment and PSTN routing.

    Please download and run the LYNC Planning tool for plan out the deployment and Hardware sizing.

  • You deploy a mediation server and gateway in Country B, and the gateway connects to Country B Pstn provider. Sitting that all the Country B calls will be routed to Country B gateway by voice policy in central Lync deployment.
