Recently I received a phone call, went back to find out what time it happened, and there is no evidence on any of the older or newest call display equipment (one of the phones is 2 months old) of the call ever having occurred.
Yes, there was incentive on the caller to hide the fact they ever called me, even if the phone number was blocked, which is why I went looking. Any thoughts on how this could be done? sorry if this is a simple thing to do but its new to me. One other item - the voice quality of the call was quite exceptional.
