How can I shout a message to several extensions

I need to create an extensions 666 that when called will allow me to barge into 20 extensions 2001, 2002,2003 … 2020 and shout someting

the person who will call will only be able to shout but he cannot hear the other end

Any idea on how can I achieve this?


Use the Page application.

Page only works for idle devices. (There is only one extension involved here, the one that is called to initiate the barge in - that’s why I say device here.)

So my question is now, how can I barge many lines and to be able only to speak and not to hear??

As @navaismo said use page application.

exten => 111,1,Page(SIP/101&SIP/102)


As I said, he is trying to do this on channels that are up. He needs to get them into a conference bridge or use the chanspy type audiohooks. Producing a design for that is well beyond the scope of a peer support forum.

Sorry missed the barge part. Yes only with an elaborate dialplan using chanspy.
