The issue seems to be that the voicemail system is treating the message

it also does so if the user issues TOP instead remains to be seen, but
is easily tested using telnet)
That means there's some private sharing of state between the POP3 server
and the voicemail server. For example, maybe the POP3 server is adding a
header (e.g. Status:) after a RETR command, and the voicemail server is
looking at this header. Or maybe the voicemail server is accessing the
message directly, not using POP3 at all; e.g. if it were a Maildir then
it might be looking at flags on the filename (:2,S for Seen)

Yes. The mailbox obviously has its own "seen" flag which the POP server
affects.
But that doesn't help you much, since you can't control that internal
state by means of the POP3 protocol.
My bet is that TOP will not affect that internal seen flag, while RETR
does.
