Teknoids

Our legal clinic has offices here that are used for observed interviews.
They currently use the phone system as a microphone to listen to the the
interview, which they want to replace.

I'm told they want something like what is used in the cops shows on TV.
Not being a fan of such shows, I'm at a loss to help them. :)

What do other schools use so the faculty and other students can listen
into the conversation from another room?

TIA!
