Jingwei,

the dialplan command eavesdrop does this. The person barging in can use key presses to dynamically turn on/off voice.

Hi Guys,

Is it possible to restrain the call-out to be one-way, meaning the callee can only listen, but not speak? If so, is it possible to switch off the constraint dynamically during the call and allow the callee to speak?

Thanks,
-Jingwei
