Prerequisite Features
There are no strict prerequisites, however this feature will not do anything unless the DialVoicemailServer session state field has been set to true.
Normally this will be done by the VerticalServiceCode feature.

This feature depends on subscriber data provisioned in Forward-To-Voicemail section of the Metaswitch-TAS-Services document in the HSS.
The following attribute from that section is used:
| Name | Type | Description |
|---|---|---|
voicemailServer |
String |
The URI for the voicemail server to connect to. |
See the Metaswitch-TAS-Services Schema to Session-State Fields mapping for more details about the Metaswitch-TAS-Services document.
Behaviour
This feature redirects the calling party to their voicemail server.
It will only do this if the DialVoicemailServer session state field has been set to true.
Normally this will be done by the VerticalServiceCode
feature when a subscriber dials a special number that has been configured with a vertical service code action.
There is a vertical service code action included in the out of the box Sentinel VoLTE deployment that can be used to do this. A full list of all pre-configured service code actions can be found here: Supplied Vertical Service Code Actions.
