Configuring Operational Features

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.

Use the following procedure to configure the XML application and off-hook 
interaction feature.

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

For the specific parameter you can set in the configuration files, see Appendix A, the section, 

page A-239.
