The Digitool MX does not have an Echo cancellation feature. You would have to use a Media Matrix Nion system to have this feature.

However without echo cancellation, you would need a design that would mute the microphones in any classrooms that we being sent audio. Now this could be done with the Digitool MX, via of the 8 presets. However you could not have 8 individual classroom pages and an all page as well as that would require 9 presets. You could program it with presets to call seven classrooms, plus an all page. Or perhaps to classrooms could be addressed as one.
