Now, I haven't happened upon this in a VoIP context yet, but I do accasionally see it for email. Unless I have a <i>very</i> pressing reason to contact that person, no mail will be sent. If I just had a comment about something they said on a mailing list or some notes about a draft they wrote or something, they probably won't get to see that.
