@lanodan @coolboymew on modern android your "phone" app is splitted in 4 tabs : "keypad", "recents", "contacts" and 🥁"voicemail" where you have a menu with your incoming messages and buttons to play/pause/delete them.
You don't have to call your voicemail server anymore.

Some operators even send you an sms transcript of your incoming messages (quite effective and sometimes even funny). i don't even listen to my voicemail anymore, this sms is enough 90% of the times.
