For many businesses and professionals, your voicemail greeting is going to be the first point-of-contact for your customers. This is especially true for service businesses, who often rely on their voicemail to collect information from interested parties.
If your carrier supports the iPhone voicemail feature, you can retrieve and listen to your voicemail right from within the “Phone” app and call your contacts back by simply tapping their messages. That type of functionality is pretty neat and useful, because it saves you actual time. If not supported by your carrier, you will not be able to see the visual overview of your voicemail inbox and use any of the related features. Tapping the “Voicemail” tab in your “Phone” app will simply call the number associated with your voicemail box. So let’s get going with creating our custom voicemail greeting on iPhone!

However, most networks do allow you to adjust the length of time that the phone rings before switching to voicemail by dialing in a long code number. On Vodafone this is **61*121*11* followed by the number of seconds and then the hash symbol (#). So to set your phone to ring for 20 seconds you’d dial **61*121*11*20*.
