Overview

1
This chapter provides an overview of the Microbrowser available on SoundPoint IP 330/320, 430, 501, 550, 600, 601, and 650 desktop phones and SoundStation IP 4000 conference phone.
It also provides an introduction to XHTML and guidelines for the application development.
This chapter contains information on:
What is the Microbrowser
What is XHTML
How to Create Applications
To develop an application that can run on the Microbrowser, refer to
Application Development on page 2-1. To troubleshoot any problems with
your applications, refer to Troubleshooting on page 3-1.

What is the Microbrowser

The Microbrowser is like any Web browser—Microsoft Internet Explorer and Firefox, for example—but supports only a subset of XHTML features. It can connect to Web servers hosted in the Internet or intranet and download XHTML pages. The Microbrowser supports a limited number of XHTML 1.0 features—it does not have full Web browser functionality.
The Microbrowser downloads XHTML content from a Web server into the phone’s memory, then parses the content to identify XHTML tags and renders these tags onto the phone's graphic display. The appearance of the rendered page depends on the graphical capabilities and display size of the device on which the browser is running. Complicated pages should be avoided on devices with very small displays.
The Microbrowser does not support scripting (such as JavaScript). All actions on data entered into forms is processed by the server using POST or GET methods.

Developer’s Guide SoundPoint IP / SoundStation IP
The XHTML pages displayed on the Microbrowser can contain static or dynamic information.
Static XHTML. These pages are created using XHTML editors and hosted by the Web server. These pages are accessed from the Microbrowser (using HTTP protocol) by entering the URL to access the page. These XHTML pages are called static, because the information that is displayed is already coded into the XHTML pages. These pages do not include information that keep changing or contact other services for update.
Dynamic XHTML. These pages involves dynamic information updates of XHTML pages by an application hosted on the Web server. The application residing on the Web server will get information from an intranet or through the Internet—data service providers like Yahoo, Exchange Server, Call Control Servers and other enterprise servers.
Users can launch the Microbrowser on a SoundPoint IP or SoundStation IP phone by pressing the Services key, or if there isn’t one on the phone, it can be accessed through the Menu key by selecting Features, and then Applications.
Note

What is XHTML

As of SIP 2.2, the Services key and menu entry were renamed Applications, however the functionality remains the same.
The Microbrowser is supported on:
SoundPoint IP 330/320 - screen resolution - 102*22 pixels (3” by 1”)
SoundPoint IP 430 – screen resolution – 132*46 pixels (3.5”*1.5”)
SoundPoint IP 501 – screen resolution – 160*80 pixels (4” by 2”)
SoundPoint IP601/650 – screen resolution – 320*160 pixels (4” by 2”)
SoundPoint IP 4000 – screen resolution – 240*68 pixels (2.4”*0.8”)
XHTML is the abbreviation of eXtensible HyperText Markup Language.
XHTML 1.0 is a transformation of HTML 4.01 into valid XML. The use of the stricter XML syntax makes parsing of XHTML much easier for small clients, but XHTML 1.0 was also the first step towards making HTML easily extensible. Moving to XML allowed the methods used to create XML extensions to apply to HTML as well. Step two occurred with XHTML 1.1, where XHTML was divided up into ‘modules’, where any features above and beyond a skeleton set were grouped into individual modules. User agent (UA) developers could then decide which extensions to support. A simple user agent can be considered a fully compliant user agent by supporting only the Basic module, whereas a more powerful browser can support all the official modules, as well as those developed by third parties.

Overview
Modularization is also intended to help content creators. As more and more devices become web-enabled, the number of platforms a content creator will be asked to support will become unreasonable. By dividing HTML up into different ‘building blocks’ content creators can supply a minimal version of their site for user agents that only support the Basic module, a moderate version of their site for user agents who support the additional modules, and a full version of their site for user agents that support the full range of the XHTML specification.
Finally the X in XHTML was intended to help people who wish to extend HTML. The use of XML brought a standard grammar with which they could define their extension, and the modularization meant that their extension would be just another module that a user agent developer or content creator could choose to support. Additionally, since XHTML pages should state what modules are required to accurately render them, the user agent software could dynamically load a ‘plug-in’ that it could use to render a module that was defined after the user agent had been originally released.

How to Create Applications

You can design the following types of applications:
Web browser
Company directory
Stock ticker
1 - 3
Developer’s Guide SoundPoint IP / SoundStation IP
Depending on the type and complexity of the application, you might use one of the following tools for creation:
Text editor
XML editor
Microsoft Word
When designing applications, you might want to consider the following guidelines:
Note
These guidelines are for your information only. You are solely responsible for determining the suitability and applicability of this information to your needs.
1. Spend sufficient time designing the application by:
Developing a conceptual design
Describe all user-application interactions
Plan for all user types
2. Create standardized applications to assist in:
Lowering design time
Speed up debugging
Increasing usability
3. Promote consistent output and predictable user input.
4. Create a prototype application to test on sample users.
5. Thoroughly test your application before releasing to:
Identify all user interface issues
Verify that all error conditions are caught cleanly
For step-by-step instructions on how to develop an XHTML application that can be run on the Microbrowser of all SoundPoint IP and SoundStation IP phones, refer to Application Development on page 2-1.
