View products that this article applies to.

Symptoms

Consider the following scenario:
  • You enable the Collocated Mediation Server option in a Microsoft Lync Server 2010 Front End Server pool in a Lync Server 2010 environment.
  • You deploy a Front End Server in the Lync Server 2010 Front End Server pool.
  • You enable the Limit service usage to selected IP address option, and then you configure the Primary IP address and the PSTN IP address of the Front End Server.
  • You register the Primary IP address on the DNS server. However, you do not register the PSTN IP address on the DNS server.
  • You deploy the Mobility service in the environment.
In this scenario, the Front End Server does not route network traffic to Microsoft Lync 2010 Mobile clients. For example, a Lync 2010 Mobile user cannot receive instant messages from federated users or from other Lync 2010 Mobile users.
