Testing audio on devices with the "echo" contact
Zello uses a special contact named "echo" to allow users to test the audio on their devices.
When a new Zello Work network is created, the "echo" user is created by default.
In order to use the "Echo" robot to test device audio, it must be added to a user's contact list.

Note: You will be charged for having the echo user in your network. Feel free to delete it.
