02 lenghth of call before voice mail

A classic!

In the United States, the standard length of time before a call goes to voicemail is typically 2-4 rings. This is known as the "ring cycle" or "ring duration."

The exact length of time before voicemail can vary depending on the phone service provider, the type of phone, and the specific settings of the phone or voicemail system. However, 2-4 rings is a common range for many phone services.

Here's a breakdown of what might happen during this time:

1. Ring 1: The caller's phone rings for the first time, and the recipient's phone rings for the first time.
2. Ring 2: The caller's phone continues to ring, and the recipient's phone continues to ring.
3. Ring 3: The caller's phone continues to ring, and the recipient's phone continues to ring.
4. Ring 4: The caller's phone continues to ring, and the recipient's phone continues to ring.
5. Voicemail: If the recipient doesn't answer by the 4th ring, the call goes to voicemail, and the caller can leave a message.

Keep in mind that some phone services or voicemail systems might have different ring cycles or settings, so the exact length of time before voicemail might vary.
