Federation Requirements for Push Notifications

Federation must be configured with the Microsoft Push Notification Clearing House to deliver push notifications to Apple and Microsoft mobile users. In Lync Server 2013, this is done by adding a new hosting provider configuration. Perform these steps to enable the hosting provider for push notifications:

1. Open the Lync Server Management Shell (PowerShell).

2. Run the following command to add the hosting provider:

New-CsHostingProvider -Identity <Lync Online hosting provider> -Enabled $True -ProxyFqdn <FQDN for the Access Server used by the hosting provider> -VerificationLevel UseSourceVerification

The following example shows the command that would be used for companyabc with an the Push Notification Clearing House identity being sipfed.online.lync.com:

New-CsHostingProvider -Identity LyncPush -Enabled $True -ProxyFqdn sipfed.online.lync.com -VerificationLevel UseSourceVerification

3. Add push.lync.com as an allowed SIP domain by running the following command:

New-CSAllowedDomain -Identity push.lync.com

At this point, the federation configuration is complete for push notifications. Follow the steps in the section “Steps to Enable Mobility” to enable Mobile access and push notifications for those clients.
