SIP IP Phone Models 480i, 480i CT, 9112i, 9133i Release Notes

A new HTTP refresh header feature has been implemented on the IP phones. This 
feature includes the following:

•

All current XML screen objects have the ability to be refreshed by adding a 
Refresh and URL setting to the HTTP headers. (see Refresh setting format 
below)

•

The Refresh setting is set by the XML application and it is up to the 
application to decide which objects it wants to refresh.

The Refresh setting must be included in the HTTP header. The XML application 
decides which objects it wants to use with this setting. The phone recognizes this 
setting when parsing the HTTP header. If the setting is present, then it passes 
along the refresh timeout and the URL to the ParserData object, which all XML 
screen objects inherit from. The ParserData class also has a timer, which must be 
set to expire at the next refresh time. When the timer expires (time to refresh the 
screen), the phone requests the URL again and displays the refreshed screen.

The following is the Refresh setting format for the HTTP header:

The following example is a Refresh setting for use in an HTTP header:

This HTTP refresh header feature only applies to objects that 

display to the screen.

You must use the Refresh and URL parameters in order for this 

feature to work in the HTTP header.
