Creating an XML Application

The IP phones support an XML AastraIPPhoneStatus object for displaying 
status messages on a single designated line on the phone’s idle screen. The 
messages display when the server pushes XML information to the phone.

The 57i/57i CT phones display messages on the second line in the phone window. 
(where “No Service” would display if there was no service. If there is no service 
on the phone, the “No Service” message overrides the XML object message). The 
53i phone displays messages on the first line (overriding the DisplayName). The 
phone truncates long messages that are wider then the phone screen.

If the phone receives multiple messages, the first message received displays first 
and the remaining messages scroll consecutively one at a time. Messages remain 
displayed 

until they are removed (by the server) or

 the phone reboots. The 

AastraIPPhoneStatus object feature is always enabled.

The AastraIPPhoneStatus object describes the structure of the XML document 
that you can use to send status messages to the phone. The basic structure of the 
AastraIPPhoneStatus object is:

<AastraIPPhoneStatus>

<Session>My session ID</Session>
<Message index="Msg index">Message</Message>

<! -- Additional status messages may be added under new Message tags-->
<AastraIPPhoneStatus/>

The ”My Session ID” attribute must be unique to the application sending the 
XML object to the phone. The application generates the session ID, which could 
be a combination of letters and numbers. There is a maximum of one <Session> 
tag per PhoneStatus object, so the <Session> tag is optional.

You can set the amount of time, in seconds, that a message displays 

to the phone before scrolling to the next message. For more information 
about this feature, see
