How to Set Up the VMI Connection

An environment variable on the Vocera Environmental Services Integration server specifies the IP address of the Vocera Voice Server or cluster. The IP address list is written into the EVS database, and the system uses it to direct VMI requests to the appropriate Vocera Voice Server.

To set up the VMI connection:

  1. On the Vocera Environmental Services Integration server, display the Advanced tab of the Windows System Properties dialog box.
    For example, on Windows 2012 Server do the following:
    1. Right-click the Windows icon and select System.
      The Windows System dialog box appears.
    2. Select Advanced System Settings.
      The Advanced tab of the Windows System Properties dialog box appears.
