How to Create an XML Application

Creating an XML Application
Appendix G XML Support for Answer and Ignore Softkeys
When the IP phone receives an XML application (either via a post or an incoming
action URI) while a call is coming into the phone, the user can either answer or
ignore the call with new softkeys that display (55i, 57i, and 57i CT), or press the
left and right arrow keys (53i), without canceling the XML application.
For a 55i, 57i, and 57i CT, an Administrator can use the “Answer” and “Ignore”
attributes in an XML script to implement this feature. For a 53i, an Administrator
can use the “allowAnswer” attribute with the AastraIPPhoneTextScreen XML
object. Valid values for the “allowAnswer” attribute are “yes” or “no” (default).
For 55i, 57i, and 57i CT:
• The Answer and Ignore softkeys display on the LCD when the phone has an
incoming call at the same time it receives an XML application.
• XML applications are destroyed if the phone receives a call after the XML
has been rendered.
When the Answer softkey displays, you can press it to answer the incoming call
without disturbing the current XML application. When you answer the call, the
softkey disappears from the LCD. Pressing the Ignore softkey ignores the
incoming call without disturbing the current XML application.
Implementation (55i, 57i, 57i CT)
Softkeys:
• 1=Answer
• 2=Ignore
