Chapter 5 Internal URI Features

XML Displayable Object URIs

Delete

http://server/delete.asp

Example 5-1

shows how to use the QueryStringParam URI in a

CiscoIPPhoneMenu

object. The

CiscoIPPhoneMenu

object includes two MenuItems with QueryStringParam URIs. If the user chooses the

MenuItem(s) with the numeric keypad, the cursor moves to that entry, but nothing executes because the
values are QueryStringParam URIs.

If the user presses either custom softkey, the currently highlighted MenuItem URI value gets appended
to the softkey URL that was pressed and requested from the web server.

If you highlight the first MenuItem and press the Read softkey, the phone generates the following URL:

http://server//read.asp?message=1

Example 5-2

Selecting an Item with Numeric Keypad Calls the URL

Message List

Two Messages

Messae One

http://server/messages.asp?message=1

Messae Two

http://server/messages.asp?message=2

Read

1QueryStringParam:action=read

Delete

2QueryStringParam:action=delete

The Cisco Unified IP Phones allow you to implement the QueryStringParam URI in either manner
although

Example 5-2

is not as efficient as

Example 5-1

. Choose the best way to perform the action

based on your applications needs.

Example 5-2

does have a slight advantage in that if the user chooses an item with the numeric keypad,

the URL gets called. This would allow you to invoke some default behavior such as to read the message
in the example. By highlighting the first message and pressing the Read softkey, the phone creates the
following URL: http://server/messages.asp?message=1&action=read

Using the QueryStringParam URI reduces the size of the XML objects that you generate by not having
to repeat redundant portions of a URL in every MenuItem.
