Why can't we do it ourselves anymore? It was one of the best features that Fido had years ago... Of course it's gone now.
Considering I supposedly have an unlisted number, I'm shocked at how many spam calls I get, too! Same thing as the OP , a recorded message in an Asian language. It's clogging up my voicemail!
That's not my main reason for writing, though, there are just times when I would like to be able to turn it off for a day or two.
