When your number is blocked by someone, the specific behavior you will encounter can vary depending on the phone carrier and the settings of the person who has blocked you. In some cases, you may hear a busy tone when you call, while in other cases, the call may go straight to voicemail or be rejected without any notification [1].

Here are some possible scenarios when your number is blocked:

1. Busy Tone: In some cases, when you call a person who has blocked your number, you may hear a busy tone indicating that the person is currently unavailable or busy [1].

2. Straight to Voicemail: Another possibility is that the call may go straight to voicemail without ringing. This can be an indication that your number has been blocked [2].

3. Call Rejection: In certain situations, the call may be rejected without any notification. This means that when you call, it will not connect and you will not receive any indication that your call has been blocked [2].

It's important to note that the exact behavior may differ between different phone models and operating systems. Additionally, other factors such as network issues or the person's phone being turned off can also affect the call experience [2].

If you suspect that your number has been blocked, the best course of action is to communicate with the person directly to clarify the situation. They will be able to provide you with more information about the status of your calls and messages [2].
