Monitor picked call

Is it possible?
Without one touch record, but automatically?

Use MixMonitor() before answer the call

But what what if ringing extension should not be monitored?
I need to monitor extension which picks call up…

I think the b option

b
Saves audio to the file only while the channel is bridged, i.e. once a conversation has actually begun, and only until it is hung up.

So it seems that it is only option to monitor extension which will ring and be picked up, right?

once a conversation has actually begun, and only until it is hung up.

Yes, I know. Let me explain what I am talking about:

ext 100 rings

ext 101 picks up

I want this call to be monitored without setting monitor on ext 100.

You mean just monitor who pick up the call in this case 101, for this purpose Mixmonitor() wont work,

Use the ami action Monitor

Yes that’s it.
