Your call cannot be completed as dialled

Ho lee crap!  I can now, hopefully, include genuine telecom sounds in a recording of the song that I’ve tried to name so many times without success that I now refer to it mentally as ‘the telecom song’ (a song, Debbie, that’s so old that I actually lived in the same building with you when I wrote it!!).  It’s also known as “Your call cannot be completed as dialled” and “Words Fail”.
