Federating with External Lync Platforms

Brian Hadfield -

Lync federation lets you communicate faster and more effectively with other Lync users outside your organization, such as partners, suppliers, customers, or vendors.

When enabled, Lync federation allows you to:

  • Add users from other organizations to your Contacts list.
  • Send instant messages to your federated contacts.
  • Invite contacts to audio calls, video calls, or conferences.
  • Exchange presence information.
  • Escalate person-to-person instant messages to multi-person conferences.

Enabling Lync federation requires additional configuration beyond the simple provisioning of the tenant account.  The additional configuration required depends upon the type of federation that is desired.  The available federation options are listed below along with the associated requirements.

Federation Options

  1. Intra-platform federation allows for federation between tenants on same Lync platform.  The only configuration requirement for intra-platform federation is for the sip domain of the federation partner to be added to the Federated Domains: list in the Control Panel.  To add a domain to the Federated Domains: list, perform the following steps
    1. Login to the Control Panel as a Company Administrator or Reseller Administrator
    2. Open the Company Information screen
    3. Click on Lync 2013 Hosting Service from the Active Services Window
    4. Add the desired domain to the Federated Domains: list by typing it in the Domain to Federate: box and clicking on the green check.

    1. Click Update to apply the changes.
    2. Federation should now be active.
  1. Direct External Federation allows for federation between tenants on different Lync platforms but requires additional configuration steps on the external platform.  To configure Direct External Federation, perform the following steps:
    1. Add the SIP domain of the external platform to the Federated Domains: list in the Control Panel (See step 1 above for details).
    2. Have the external customer update their Lync platform to include the following:
      1. Add the sip domain of the internal company (sip.customerdomain.com) as a direct federation partner
      2. Add an access proxy entry for the sip domain of the internal company (sip.customerdomain.com) that points to access02.partnerhosted.com.
      3. Federation should now be active.
  2. Dynamic External Federation allows for federation between tenants on different Lync platforms and may not require any configuration on the external platform.  Dynamic External Federation does however, require the sip domain of the internal customer to be added as a Subject Alternate Name to the Lync Edge Certificate that is deployed on the internal platform.  For costs and further details associated with adding a tenant sip domain to the certificate, please see your price list or contact your sales representative.  To configure Dynamic External Federation, perform the following steps:
    1. Add the SIP domain of the external platform to the Federated Domains: list in the Control Panel (See step 1 above for details).
    2. Confirm that all required DNS entries have been made for the platform.  The required DNS entries can be found in the DNS requirements to use Chinook services article in our Support Forums.
    3. Complete the federation requirements on the external platform.
      1. If the external company is configured for open/dynamic federation on their Lync platform, no further action is required and federation should be active.
      2. If the external company is configured for direct configuration, they will need to add the sip domain of the internal customer to their Federated Partner list, but will not need to add an access proxy entry.
    4. Federation should now be active.

NOTE:  The process to update and re-install an SSL certificate can take several days to complete.
