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

[illuminati500]

How about running a length of transparent zip wire along the phone cord and making a hard connection to the speaker. You might want to consider replacing the existing speaker.

Now the director would like to have audio from one of the other characters coming through the handset speaker.   I have a pretty good idea of how to make this work but I have a couple of questions of the hive mind to see if I have all bases covered. If there is a device for doing this that would be the best solution.
