Using a SIP loudspeaker device

A SIP loudspeaker device can be seen as a SIP phone with autoanswer, allowing anyone to dial in and have a message played. It can be comfortable to have a professional recorded, predefined message to be played, without relying on spoken words. To make this, you need to load the message in the system as a normal media file and then create a Flow playing the message

Flows and the conferences are the only destinations allowed for the "Originate" Custom Destination

Once created the Custom Destination, just use in your feature code of choice. Maybe you can add an "Authenticate" condition to avoid abuses.
