Your Quobis Collaborator account may have an integrated voicemail if your administrator has enabled it. To access to it, you will find a button on top of your “Call history” tab as shown on the screenshot.
Quobis collaborator will let you know when you do have new messages, as you will see a notification dot with the number of messages.
Also this counter will be shown in the “Call history” tab button in addition to the missed calls.
Once you press the voicemail button, the call will start and you should be prompted to introduce your password. Inside the voicemail you’ll be able to navigate through new and old messages, record a new automated answer and configure the voicemail.
Please note that the behaviour of each voicemail will depend on your specific installation, check with your system admin how to change your access password.
