Creating Push Messages

46 4600 Series IP Telephones Application Programmer Interface (API) Guide

The Audio Push Type

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 pushed audio stream by taking one of the following actions:

● By going on-hook, for example, picking up the handset or activating the headset,

● By pressing the telephone’s Speaker button,

● By pressing the telephone’s Drop button, or

● By selecting a Call Appearance button.

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.

Audio Push Features

The Audio push type provides the following features:

● Telephone connection to an incoming RTP stream

● A “pure” stream, not a telephone call

● Temporarily replacement of the active stream

● Audible alerts

● A built-in timer to display the stream for given period of time

Alerts

An Audio Push Message can be sent with accompanying alerts. Alerts are a number of ring

pings sounded just prior to displaying the message on the screen. With an Audio push type, an

alert can be sounded with 1, 2, or 3 ring pings. If the alert attribute is not associated with the

<Push> tag, then no alerts are sounded. Alternatively, if the alert attribute is set to “0” no

alerts sound.
