TalkShoe's system is robust allowing a very large number of people to participate on a live call.
  • 250 people can call in to talk on audio, at the same time
  • 300 people can listen to a call and chat in text, 
          at the same time, via one of the two chat clients
          (the Web Client and the Pro Client)

  • Thousands of people can listen to (but not participate on)
          a call via the Dynamic Widgets and via the iApp website

In addition, an unlimited number of people can listen to a recorded call, 
after the call has ended, from the host's call series page!
