The vast majority of voicemails that I get from unknown numbers are a prerecorded pitch about improving SCO. Too bad I registered some websites before there were privacy options to prevent personal info from appearing in a whois lookup.
Even better: let me set a list of keywords that flag or delete messages if they appear in the transcription. Sigh.
These people will call again if you don’t have voicemail and you didn’t answer.
I don’t answer unknown numbers. Letting them keep calling without vm transcripts to screen them does me no good. Also, I want to know about a family member in the hospital right away.
