The Global Message Services object is a child of the Call Services object.
The Global Message Services object contains global configuration parameters and statistics for the Voicemail System and Reminder Calls services. There is a single Global Message Services object; it is created before delivery of the MetaSwitch NE and you cannot delete it.
To configure the switch to support Message Services, you need to do the following:
Most parameters relating to each of these services are visible in the EMS System Explorer only when the service is set to Configured or Disabled.
