How can you tell if someone intentionally forwarded you to their voice mail?

You can often tell if someone intentionally forwarded you to their voicemail if you hear a few rings followed by an immediate transfer to voicemail, suggesting they didn't answer in time. Additionally, if you receive a text or notification shortly after attempting to call, indicating they were unavailable, it might hint at intentional forwarding. Lastly, if this behavior is consistent with that person, it may further suggest they are screening calls.
