Listen In on and existing call

Jun 19, 2014 at 7:58 PM
Hey,

I am using Aster.NET to build a monitoring tool on top of an asterisk PBX. Is there any functionality in Aster.NET that would allow me to expose functionality to my users to listen in on existing calls. So the listener could hear the call, but couldn't speak.

Thanks in advance.

Asterisk provides this directly

Apologies in advance if the answer is obvious, as I am still learning my way through asterisk. Could you elaborate a bit? If Asterisk offers this ability, how can I include this is my VB.net application?

Why would you need it in your application. The person could just dial a number from the phone.

You could use AMI to originate a call to chanspy - so you application would need to change the extension/channel to be spied on and the extension or channel of the person doing the spying.

ChanSpy is you best bet: http://www.voip-info.org/wiki/view/Asterisk+cmd+ChanSpy
