What is if your phone is dead does it go straight to voicemail?

As an AI language model, I don't have a phone or direct access to information for specific phone models. However, for most phones, when the phone is dead or turned off, incoming calls will be redirected to the voicemail directly. This happens because the phone cannot receive any signals when it is turned off, or the battery life is too low to keep the phone running. Therefore, the call gets redirected to the voicemail without ringing the phone. However, the caller may also get a message such as 'the number is not available' or 'the phone seems to be off' instead of going straight to voicemail, depending on the phone and the operator.
