Setting Up an Intersite Link Between Cisco Unity and Unity Connection Gateways
This section describes the prerequisites for setting up an intersite link to connect a Cisco Unity server, failover pair, or Digital Network to a Unity Connection server, cluster, or site, and provides a high-level task list of all of the tasks that you need to complete for the setup in the order in which they should be completed. If you are unfamiliar with intersite link concepts, you should first read the “Overview of Networking Concepts” chapter and review the task list and procedures before beginning the setup.
Prerequisites for Linking Cisco Unity to a Digital Network
-
At least one Cisco Unity release 12.x server is already installed and connected to the network as applicable for your installation. You can link a single Cisco Unity server or a single Cisco Unity Digital Network to Unity Connection.
-
Your Cisco Unity and Microsoft Exchange environment must be meet the requirements listed in the “Cisco Unity Connection Networking Requirements” section of the Networking Options Requirements, available at http://www.cisco.com/en/US/docs/voice_ip_comm/unity/compatibility/matrix/cunetoptionsreqs.html.
-
The Cisco Unity server that acts as the gateway to the Unity Connection site must be able to route directly to the Unity Connection site gateway via HTTP on port 80 or HTTPS on port 443.
Prerequisites for Linking Unity Connection to a Digital Network
-
You can link a single Unity Connection 12.x server or cluster or a single Unity Connection site to a single Cisco Unity server, failover pair, or Digital Network. To link a Unity Connection site, all servers in the site must be running version 12.x.
-
If you are linking a Unity Connection site, the site has been set up according to the “Setting Up a Unity Connection Site”.
-
The Unity Connection site must meet the requirements listed in the “Requirements for Intersite Networking” section in the System Requirements for Cisco Unity Connection Release 12.x at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/12x/requirements/b_12xcucsysreqs.html.
-
You have access to an account that has the Manage Servers privilege on the Unity Connection server that serves as the gateway. (The System Administrator and Technician roles each have this privilege.)
-
The Unity Connection server acts as the gateway to the Cisco Unity site must be able to route directly to the Cisco Unity site gateway via HTTP on port 80 or HTTPS on port 443.
