Sending calls to voicemail on an iPhone is a convenient way to manage incoming calls when you are unavailable to answer them. You can set up voicemail to automatically answer calls after a specified number of rings, or you can manually send calls to voicemail by pressing the “Send to voicemail” button on the incoming call screen.
There are several benefits to using voicemail on your iPhone. First, it allows you to screen your calls and only answer the ones that are important. Second, it provides a way for callers to leave you a message if you are unable to answer their call. Third, voicemail can be used to store important messages for future reference.
