Hi there! I am trying to set up a flow to dial a call from CLI and add it to a conference room when it´s answered.
I was able to start a call from CLI with this command
You should originate the call to an IVR that answers the channel and plays an appropriate announcement, then makes the callee do DTMF input before going to the conf bridge. It will prevent voicemail and other undesirable recordings from going directly into the conference.
