I was not able to find any documentation on this. Basically all I want to do from my frontend. Is post an event to the backend. Basically run the command: uuid_broadcast 69d58330-7f7f-4e52-bb2c-9e25d9f5238b event::Event-Name=HOLD.
I'm able to connect to the dialplan and drop the caller (PSTN/ITSPs) and verto client into a conference and the audio is flowing. I just want to send a message to the backend to tell it to do things. In my example above I want to set the caller on hold.
