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
Chapter 6
, the section,
“XML URI for Key Press
Simulation”
on
page 6-52
.
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-242.
