Yes. It is always best practice to leave a live voicemail if you do not have permission to leave a prerecorded message or wish to take a personal approach.
To leave a live voicemail you will need to edit your disposition settings for your voicemail button.
Then, when you reach a voicemail greeting, wait until you hear the beep, leave your live voicemail; then click the voicemail button to disposition and hang up the call.
To Edit your Dispositions:
1. Click on your initials>Dial Session Settings>Dispositions
2. Select the Dialing set that you want to Edit
3. Click the Voicemail Button to open the Edit Screen
4. Update the Voicemail Setting to Live Voicemail and then Save your changes
