The voicemail email notification now provides the transaction ID, allowing you to track the queued voicemails better. An email notification for a voicemail is generated as a result of:
Voicemail Queue Notification: When a caller leaves a voicemail via a voicemail queue, an email notification is sent to the email address configured for the voicemail queue.
IVR Settings for Voicemail: A voicemail being sent to an agent from the voicemail queue. The agent requests an email to be sent to the agent.
Transferring to Agent Voicemail: A voicemail being sent to an agent after the caller calls and leaves a voicemail in the agent’s voice box.
Additionally, you can retrieve the following information from a voicemail notification sent by email:
Tenant name
Cluster ID
Phone queue ID
Voicemail queue ID
Calling name
Interaction GUID of the inbound phone queue
Transaction ID of the inbound phone interaction
Voicemail begin offset
Filename
Agent name
Voicemail retrieval delay

To configure voicemail notification, go to Queues/Skills > Voicemail Queue > Notification and select the Enabled checkbox. You can enter more than one email address for the notification. See Configure Voicemail Notification for more information.
