If the recipient of the call does not answer, and it goes to voicemail, the following message will appear on screen:
An auto message will then play, explaining that ‘X’ is currently unavailable and to leave a message after the beep. A beep then sounds. So, the voicemail is only replicating a set of circumstances that could potentially happen with a phone answering service.
The voicemail settings can be configured if you go to ‘Settings’ from your Teams profile (your face or intials on the top-right of the teams software). The voicemail message can be re-recorded (ie. personalised), or the service turned off, among other options.
If you would prefer not allow callers to leave a message you can select the option to ‘end the call without playing your greeting’, as shown in the screenshot below.
