I have only ever had 3 phones, and this same behaviour occured on all 3, but it is annoying, so I hope it is not a standard feature. If I miss a call, and the person does not leave a voice message, the missed call is recorded in the All Calls list, and calling them back is simple. If I miss a call, and the person does leave a message, then the call is not listed at all. So if I do not recognize the voice, or if I don't have the number I can't call them back. I vaguely remember finding some option to readout the number in voice mail automated system, but I would not bother to write down and then re-dial the number usually, assuming that option exists at all, but in any case it's irrelevant to the question. Is there a way to have ALL calls, show up in the All Calls menu?
