Use an Audio push when you need to stream a particular audio message to the telephone. The Audio push is the ability to transmit RTP streams to the endpoint. This Push type provides additional capabilities such as start and stop to control audio streams. The RTP stream can also notify the phone that a stream has ended.
To the user, the telephone’s handling of pushed audio content mirrors the telephone’s handling of a call. The user can switch between Speaker, Handset, and Headset as desired, adjust volume, and view LED states as with a call. The user can terminate the audio push by going on-hook.
While the telephone is playing back pushed audio content, the call server can independently send messages that require the telephone to generate tones, for example, alert the user to an incoming call. The Volume Up and Volume Down buttons work normally if the user presses them while listening to pushed audio content.
