How can I set a repeatable voice mail reminder for missed calls that repeats every 15 minutes until answer it?
This is a work phone - so I need to be able to return missed calls. I do NOT carry it with me constantly - for example, I don't take it with me when I shower, run out to get the mail, etc. I turn off the sound during movies, funerals and at church. I sometimes don't have a signal driving to and from work. I cannot find a way to make it blink or beep when I have a voice mail waiting - like I can on my cheap personal non-smart phone. I beep is better than a blink, but either is better than nothing. This is a real issue for me.
If Apple doesn't have this functionality (which seems totally strange) is there a third-party app that would do it?
