You must use your Google voice phone number often enough for them not to disable it. I had a Google voice number. Used it infrequently. They disabled it.
They usually will send you email reminders about getting disabled soon due to inactivity and when I got those, I just open the app and call myself or text myself so it stays active.
Though, I recently got a new number and switched out my old number to transfer to Google Voice, so I’m using GV a little more often than I was before so it shouldn’t go inactive as easily.
