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
