The Push API is an XML-based application interface exposed by Avaya IP deskphones. The Push API allows client applications to push unsolicited messages to the deskphones. The push message types below are supported by the API. More information about J100 series push type support is available under Releases -> Downloads -> Push and Web APIs for the J100 SIP software release you are using.

• Display: sends a full-screen, WML page to a deskphone's web browser. This push type is not supported by Avaya J139 or J159 IP Phones.
• Top Line: sends a single line text message to the deskphone's top line display.
• Unicast Audio Receive: a separate instance of an audio message is played at each deskphone.
• Multicast Audio Receive: a single instance of an audio message is played at multiple deskphones. The Multicast Audio Receive push type is supported on 96x1 Series deskphones with H.323 Release 6.0 and higher, 96x0 Series deskphones with H.323 Release 3.0 and higher, J100 Series deskphones with H.323 Release 6.7 and higher or SIP Release 3.0 and higher.
• Audio Transmit: a message is sent to a deskphone prompting the user to use the deskphone to transmit an audio message. The Audio Receive push type can be used to play the transmitted message at other deskphones. The Audio Transmit push type is not supported by J100 IP Phones with SIP software.
• Subscribe: a message is sent to the deskphone instructing it to send its details to a subscription service. The Subscribe push method allows an application to maintain an up-to-date database of deskphones in the network.
• Phonexml: allows an application to dynamically:
  • Update a deskphone's user interface content, including the title line, prompt line, menu options, softkey labels and softkey functionality
  • Disable hard key functionality
  • Clear a deskphone's call, web and contacts history
  • Reset user-defined preferences
  • Update options and settings, such as skin, preferred language, ringtone pattern and time format.

The Phonexml push type is supported on 96x0 Series telephones with SIP Releases 2.2, 2.5 or 2.6.

Use the Application Interface Capabilities Utility, available on the Development Tools & Configurations page, to check which Push types are supported on which deskphone models and software releases.

The Avaya IP Deskphone PushSDK enables rapid development of intelligent communications applications that push unsolicited messages to Avaya IP deskphones. The PushSDK contains the client-side Java PushSDK API, associated programmer documentation and several sample applications demonstrating how individual PushSDK API operations can be combined to provide powerful solutions. The PushSDK API generates the Push Initiation requests and message content required by the deskphones' native Push API.
