Creating Push Messages
30 4600 Series IP Telephones Application Programmer Interface (API) Guide
Alerts
A Display Push Message can be sent using alerts. Alerts are a number of ring pings sounded
just prior to displaying the message on the screen. With the Display 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.
Display Push Example 1:
Following is an example of the Display push type. Assume that the Push Message (screen) in
Figure 7
will be sent to a telephone in a hotel.

Priorities and States
Display Push Content is sent with one of two priorities: normal or barge. Normal priority push
conditions are specified first, followed by barge priority push conditions.
Pushable vs. Non-Pushable States
The following are non-pushable states for Display pushes to an IP telephone:
● When the user is in text entry mode on a Web text entry screen or Speed Dial text entry
screen (for normal priority only).
● When the telephone is in the process of restoring a retrieved backup file.
● When a Local Procedure has been initiated.
If a phone is not in one of the above states, it is considered to be in a pushable state, meaning
the telephone will accept a pushed message.
