Voicemail System Link

The Voicemail System Link object is a child of the Global Message Services object. It defines the serial link over which the NE communicates with a local voicemail system using SMDI messages, to pass information about calls being forwarded to the voicemail system and/or to pass Message Waiting Indicator notifications to subscribers.


Parameter

Access

Description
Link name Change Inactive A text string used in the EMS System Explorer to identify this link. Specify a string of up to 64 characters.
Device name Change Inactive Specifies which device is used to route this serial link. The names for each device are configured in the CRAFT menus on each NE. Specify an alpha-numeric text string, of up to 20 characters. This defaults to "DEFAULT".
Port ID Change Inactive Specifies the port number used for the serial link on the device named in Device name. Range: 1 - 99. The default is 1.
Link baud Change Inactive The baud rate for the serial link to the local voicemail system. Values:
  • 1200 (default)
  • 4800
  • 9600
  • 19200
  • 38400
Number presented on forwarded call Change Inactive Specifies which telephone number is passed to the voicemail system as the called number (and therefore which subscriber receives the voicemail message) for a call that has been forwarded. Values:
  • First
    The number that was originally called, before any forwarding took place.
  • Last (default)
    The last number to which the call was forwarded before it reached the voicemail system.
Maximum call history delay Change Inactive The maximum time delay between passing a call to the local voicemail system (over a Voicemail System Line) and delivering the call history information that instructs the voicemail system how to handle the call. Range: 2 - 6 seconds. The default is 4 seconds.
Link retry interval Change Inactive Retry interval for checking the voicemail system link to determine when it has recovered after a failure. Range: 5 - 120 minutes. The default is 10 minutes.
Operation of Message Waiting Indicators allowed Change Inactive Specifies whether the local voicemail system accessed by this link can control subscribers' message waiting indicators. If this is set to False, subscribers using this local voicemail system will not receive any indication when a message is waiting. Values:
  • True (default)
  • False
Voicemail System ID Change Inactive The 10-digit ID of the local voicemail system that this link connects to. Two or more voicemail system links can use the same voicemail system and so the same ID. This field appears only if Operation of Message Waiting Indicators allowed is set to True. Set it to match the configuration of the local voicemail system.
Suppress delivery of restricted numbers Change inactive Whether MetaSwitch should suppress the delivery of restricted calling numbers to the voicemail system. This should be set to True if the voicemail system does not check the presentation status of the calling number. Whether the voicemail system checks the calling party number presentation status can be determined by making a call to the voicemail system from a restricted number and leaving a message, and then checking whether the calling number is given when the message is retrieved. Voicemail systems designed to connect directly to switches typically do check the presentation status of the calling number. Systems designed to be positioned behind a PBX often do not check presentation status. Values:
  • True (default)
  • False

Attention Required alarm events Read only / Reset Number of times (since the alarm count was reset) that this object's alarm state has gone to Attention Required.
Alarm state changed timestamp Read only The time at which the Alarm state last changed.
