What happens to voicemails after your number gets unblocked

so without giving too many unnecessary details on my story, my number was blocked by someone, as well as some social media platforms. however recently, i saw their profile pop up on one of the social media’s i was blocked on, and i had realized that i had been unblocked. obviously the only way to know if my number has been unblocked would be to reach out and i have no intention of doing so, so i have no idea if my number is still blocked or not. but before i had realized my number was blocked, the call clearly didn’t go through (which i naively thought was just from poor connection) and so i left a voicemail. i’ve seen that voicemails still go through even if you’re number is blocked, they just go into a separate folder in that case. i don’t believe this person spends a lot of time looking at their voicemails, let alone noticing something in their blocked folder, so im curious to know that, in the case that my number was also unblocked, does the voicemail i left remain in the “blocked” folder? or is it then transferred to the main voicemail hub after doing so? or is it simply just deleted? i’m just generally curious to know what happens to that message i sent in the event that i am no longer blocked. thank you!
