Configuring Operational Features
XML Applications and Off-Hook Interaction
A feature on the IP phone allows you to specify whether the phone is prevented
from going into the off-hook/dialing state when the handset is off-hook and the
call ends.
By default, the phone behaves as follows:
You are in a call using the handset and the phone displays an XML application.
The far-end terminates the call, and a new XML application gets pushed/pulled
onto the display. Since the handset is off-hook and in idle mode, the "offhook idle
timer" starts. When this timer expires, the phone applies dial tone and moves to
the off-hook/dialing state, which then destroys the XML application that was
being displayed.
With the “off-hook interaction” feature you can set an “auto offhook” parameter
that determines whether or not the phone is prevented from entering the off-hook/
dialing state, if the handset is off-hook and the call ends.
An Administrator can enable (allow phone to enter the off-hook dialing state) or
disable (prevent the phone from entering the off-hook dialing state) using the
“auto offhook” parameter in the configuration files only.
Configuring the Off-Hook Interaction Feature
Use the following procedure to configure the XML application and off-hook
interaction feature.
XML URI for Key Press Simulation
The Phones provide a feature that allow an XML Developer or Administrator to
define XML Key URIs that can send key press events to the phone, just as if the
physical hard key, softkey, or programmable key were pressed on the phone.
For more information about this feature, see Appendix F, the section, “XML URI
for Key Press Simulation” on page F-60.
Configuration Files
For the specific parameter you can set in the configuration files, see Appendix A, the section, “Off-Hook and
XML Application Interaction Setting” on page A-239.
