Features
message is displayed in the WML Browser on the line reserved for Top Line. The behavior of
the Top Line message is exactly the same whether it is displayed in the WML Browser or on
the telephony screen. While the Top Line message is visible, the user can switch between the
WML Browser and the phone screen, and the Top Line message will still be visible. Once the
30–second timeout has passed, the Top Line message is removed, regardless of whether the
WML Browser or phone screen is visible. A message that is too long to be displayed is
truncated and appended with "..." in the WML Browser display. Due to the different display
widths available, it might be truncated at different points in the Top Line message.
Top Line on text-based IP Deskphones:
In the text-based IP Deskphones, the Top Line message is displayed as follows.
• In Avaya 1110/ 1210/1230 IP Deskphones, Top Line is displayed in the context line
overlapping the context, date and time fields
• In Avaya 1220 IP Deskphones, Top Line is displayed in infoline 0 in the same manner as
the 1120E IP Deskphone.
.
. The Top Line is displayed while the IP Deskphone screen is active. If any local menu or dialog
is activated, the Top Line disappears. Once the IP Deskphone screen is activated again, the
Top Line is restored on the display if the 30–second timer has not expired.
Audio push
Audio Push is used to stream an audio message to an IP Deskphone. The Audio push transmits
Real-time Transfer Protocol (RTP) streams to IP Deskphones. To stream audio to the phone,
an RTP port is required. The Push Agent sends the port information to the Trusted Push Server
in the GET string. The GET string contains the variable "rtpLPort", the telephone's local port,
to be used for audio streaming.
Another example is a visual voice mail web page containing an embedded URI that allows the
user to select a link and in turn start audio streaming. When the user selects the link, an HTTP
message is sent to the server that indicates that the user is interested in listening to the first
message. A response is sent to the screen "would you like to hear the 1st message?" If the
user submits "Yes", the application Push Initiator sends an audio push. Audio is streamed if
the IP Deskphone is in a pushable state.
When the speakerphone or headset is used to play back an audio stream, the associated LED
is lit (except the 1110 or 1210 IP Deskphone).
At any time while receiving pushed audio content, the user can switch between speakerphone,
handset, and headset (if applicable) as normal without interrupting or terminating the pushed
audio content. Also at any time, the user can terminate the pushed audio content.
When push Audio is received, the phone displays an Interrupt screen that allows the user to
cancel the received audio.
Normal mode receive Audio push:
The IP Deskphone plays the received audio through the speakerphone by default. While Audio
push is playing, the received Audio can be switched to the handset or headset and the audio
continues playing through this device
