Supported Topologies for Devices
Topic Last Modified: 2012-08-28
To deploy devices, your topology must be set up for Enterprise Voice. If Enterprise Voice is not currently deployed in your organization, we recommend that you use the Lync Server, Planning Tool to set up your topology for Enterprise Voice.
If you want to allow external access for devices, including the ability to use the Device Update Web service from an IP phone outside the firewall, you must also deploy Edge Servers. For details about how to set up your topology for external user access, see Topologies for External User Access in the Planning documentation.
