Is it possible to avoid needing to record my greeting / name? I'm
quite happy with "four four seven eight ...... is not available." to
be honest.

When i call 123 to get my messages, it seems to insist i record my
name, if i avoid doing so, tell it i don't want to record it now then
it says "thank you for using 3mail, goodbye", rings, then disconnects.

Having the ability to record your own outgoing message is nice, but
i'd rather not be forced to use it!
