[SML] Making a phone ring and it's handset speaker work on stage

[Ray Gibson]

How close is the audience?  This really seems like the kind of thing that
you put a tiny speaker above/under/next to the telephone and process the
audio to sound like it's coming through a handset speaker.  Much easier
than the alternative.  I think that even a close up audience would be
fooled by this.
