Hidden Properties

The Vocera Voice Server supports a few hidden properties that are updated manually in the properties.txt file. Vocera recommends calling Customer Support if you plan to manually update the properties.txt file.

Locate the properties.txt in \vocera\server\properties.txt and update these hidden properties. You must restart the server after you update the properties.txt file to enable or disable the new setting.

Table 1. Hidden properties
Property	Description
`AddToMultipleGroupsReminderPrompt`	Enable this property for customers that have a need to automatically remind users to add themselves to groups. The system automatically prompts a user at login to add themselves to groups. The behavior is not enabled by default. When this feature is enabled, after a successful login each user hears the prompt, "Would you like to add yourself to multiple groups?" If the users respond "Yes" or press the Call button, the Genie responds back with the prompt, "OK Great" and begins the "Add to Multiple Groups" dialogue. It is the same dialogue launched when a user issues the, "Add me to multiple groups" voice command. Genie prompts with, "Say a group name each time you hear the tone. Press the call button when done." This behavior is system wide. To enable the prompt edit the %vocera_drive%:\vocera\server\properties.txt file on both the active and standby VS servers and add the following two lines at the end of the file: # Remind user to add themselves to groups. Default value is false AddToMultipleGroupsReminderPrompt = true To disable this feature, set the prompt value to `False`.
`IPPhoneClientDisableBroadcastChime`	Enabling this property helps to reduce the use of multiple speech ports at the start of an urgent or non-urgent broadcast. By default, this property disabled or set to `false`. When this property is disabled, the Vocera Voice Server uses a speech port to play the chime. If this property is enabled or set to `true`, then no speech port is used to play the chime; instead, the VCS clients play the chime. Note: The VCS 3.4 clients can hear the broadcast chime, but older versions of the VCS clients do not support this functionality, and will not hear any chime. Hence, Vocera recommends enabling the feature after all clients upgrade to VCS 3.4 or a later release.
`IPVMISecureEnable`	Enables secure VMI support within the Vocera Voice Server. When this property is set to TRUE the Vocera Voice Server opens a port to listen for secure VMI client connections. The default is FALSE.
`IPVMISecureListeningPortNo`	Specifies the port the Vocera Voice Server uses to listen for secure VMI client connections. The default is port 5007.
`MsgDisableSkipMessageResponse`	Enter `true` (the default) or `false`. Set to `true` to disable the "Skip" response for VMI messages that are played aloud, forcing users to say a valid response, such as "Accept" or "Reject." Set to `false` to enable the "Skip" response. For details, see the Vocera Messaging Interface.
`SysBroadcastResponse`	Enables or disables responses to broadcasts. Enter `true` (the default) or `false`. To make broadcasts uninterruptible, set this property to `false`.
`SysLoginLicenseAlertThreshold`	If there is a login license limit, this property sets the percent age threshold at which the Vocera Voice Server will send an email alert whenever the threshold is exceeded. Enter a decimal value. The default threshold is .90 (90%) of the login license limit. For example, to increase the alert threshold from 90% to 95%, enter `.95`.
`SysMaxRejectedLogins`	Sets the maximum number of rejected login attempts before the user is prevented from logging in from that machine for one minute or the interval specified by the `SysMaxRejectedLoginsPeriod` property. Enter any positive integer.
`SysMaxRejectedLoginsPeriod`	Sets the time period (in milliseconds) that a user is prevented from logging in from a machine on which he has reached the maximum number of rejected login attempts. Enter any positive integer (the default is 60000 milliseconds, or 1 minute).
`SysFunnyGenie`	Enables or disables the funny Genie. Enter `true` (the default) or `false`.
`VMIBroadcastEnabled`	You no longer need to set this property for urgent Broadcast messages to large groups. The Vocera Voice Server has been enhanced so that unicast messages always utilize a single speech port. For details, see the Vocera Messaging Interface Guide.
`VMIResponseMapping`	Maps VMI responses passed from a middleware system to other response choices. For details, see the Vocera Messaging Interface Guide.
`VMIResponseTimeout`	Enter the number of seconds that a user can be prompted to respond to a new alert or alarm before the message times out. For details, see the Vocera Messaging Interface.
`VMITimeoutResponse`	Enter the response that is used when a new alert or alarm reaches the specified `VMIResponseTimeout`. For details, see the Vocera Messaging Interface.
`VMITouchCallResponse`	Enter the Vocera response phrase that is used when a user presses the Call button to respond to a new VMI message. For details, see the Vocera Messaging Interface.
`VMITouchDNDResponse`	Enter the Vocera response phrase that is used when a user presses the DND button to respond to a new VMI message. For details, see the Vocera Messaging Interface.
`VMITouchCallHoldResponse`	Enter the Vocera response phrase that is used when a user presses and holds the Call button to respond to a new VMI message. For details, see the Vocera Messaging Interface.

Note: If you modify the properties.txt file, you must stop and start the Vocera Voice Server to load the properties into memory.
