No, everything is possible.
If you're using an iPhone, you can do the following:
1. Find the voicemail at the bottom of the screen.
2. Scroll down to the bottom of the voicemail list and click the deleted message.
3. Here you can find all recently deleted voicemails. You can play them by clicking on the messages in the list one by one.
4. Now click Undelete to return the voicemail to your regular voicemail inbox.
I hope that you can keep your backups and don't ask how to recover deleted voicemails.
