Past few days (so far not today) have had numerous missed calls. No ring, just discover later that a call was missed. Caller tells me it either rang a few times then went to vm or sometimes immediately to vm. I want my iphone 5 to notify me and then remind me every few seconds that I have a missed call (missed calls are more important to me and my business than a text message, which does remind me). No settings to set this up. Summary: two issues... (1) why missed calls; and (2) how to be notified and reminded.
