Overview
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.

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.
As of SIP 2.2, the Services key and menu entry were renamed Applications,
however the functionality remains the same.

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.

determining the suitability and applicability of this information to your needs.
Note
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

Unsupported elements and attributes are described in Unsupported XHTML
Basic Tags
The following basic tags are supported:
•
•
<!DOCTYPE>—Defines the document type
<!--...-->—Defines a comment
<!DOCTYPE>
The <!DOCTYPE> declaration is the very first thing in your document, before
the <html> tag. This tag tells the browser which XHTML specification the
document uses. XHTML 1.0 specifies three XML document types: Strict,
Transitional, and Frameset.
•
XHTML Strict
— Use this DTD when you want clean markup, free of presentational
clutter. Use this together with Cascading Style Sheets (CSS).
For example,
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
•
XHTML Transitional
— Use this DTD when you need to use XHTML's presentational features
because your readers don't have browsers that support Cascading
Style Sheets (CSS).
For example,
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
•
XHTML Frameset
— Use this DTD when you want to use frames.
For example,
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
Frameset//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
This tag does not have any attributes.

<!--...-->
The comment tag is used to insert a comment in the source code. A comment
will be ignored by the browser. You can use comments to explain your code,
which can help you when you edit the source code at a later date.
This tag does not have any attributes.
Link Tags
The following link tag is supported:
•
<a>—Defines an anchor
The Microbrowser supports both http://and tel://URL schemes. When a tel://
URL is selected, the phone switches to the telephony application and dials the
number specified in the URL. Currently the number is dialed as-is, however, full
support for tel:// URL parsing as specified in RFC 2806 will be available in a future
release.
Note
sip://URLs are not supported at this time.
<a>
The <a> tag defines an anchor. An anchor can be used to create a link to
another document by using the href attribute.
The following attributes are supported:
Attribute
href
Value/s
Description
URL (Ex:” www.polycom.com”)
section_name
The target URL of the link
name
Names an anchor. Use this
attribute to create a bookmark in a
document.
In future versions of XHTML the
name attribute will be replaced by
the id attribute.
Note: This attribute is parsed, but
not used.
Input Tags
The following input tags are supported:
•
•
<form>—Defines a form
<input>—Defines an input field

The Microbrowser supports both the GET and POST methods for submitting forms.
Note
Nesting forms within tables is supported. However, nesting of one form tag within
another is not supported and may lead to unexpected results.
<form>
The form element creates a form for user input. A form can contain text fields,
check boxes, radio buttons and more. Forms are used to pass user data to a
specified URL.
The following attributes are supported:

Image Tags
The following image tag is supported:
•
<img>—Defines an image
The Microbrowser supports images stored in uncompressed .bmp format. While all
BMP bit depths will be displayed to the best of the phone’s ability, it is
recommended that the image format most suitable for the target platform be
chosen. For example, the SoundPoint IP 601 LCD supports four levels of grey, so a
16-color BMP format would be most appropriate.
Note
Images can be scrolled up and down, however images that are too wide will be
truncated.
Various platforms have differing limits due to memory. There are also
differing pixel limits for devices of differing pixel depth. A 1 bit per pixel
image 160x80 requires only 1600 bytes. For a 24 bit picture, the memory
requirement is 38400 bytes.
There are several limits depending on the source data (this involves the cache
limits in configuration) and the display converted data, which is dependant on
available RAM (and is limited in the code depending on platform).
<img>
The img element defines an image.
The "align", "border", "hspace", and "vspace" attributes of the image element are
not supported in XHTML 1.0 Strict DTD.
Note
The following attributes are supported:
Attribute
Value/s
Description

Meta Information Tags
The following meta information tags are supported:
•
<head>—Defines information about the document
Due to space constraints, there isn’t a static title bar at the top of the Microbrowser
window, as there is in most other browsers. The title is displayed in large bold text
in the first line of the page, and is scrolled off the screen as the focus is moved
down the page.
Note
<head>
The head element can contain information about the document. The browser
does not display the “head information” to the user. The following tag can be
in the head section: <title>.
No attributes are supported.
HTTP Support
The Microbrowser is a fully compliant HTTP/1.1 user agent:
•
It supports:
— Cookies
Cookies are stored in RAM, therefore they are not are not preserved when the
phone reboots or is reconfigured. Cookies are not shared between the idle display
Microbrowser and the main Microbrowser.
Note
— Refresh headers
— HTTP proxies
— HTTP over SSL/TLS

Developer’s Guide SoundPoint IP / SoundStation IP
— Self-signed or custom CA certificates
•
There are the following exceptions:
— There is no sophisticated caching. The HTML cache refresh META tag
is not supported.
— Any images in the body of a document with the same URL are
assumed to be the same image. The image is loaded from the
Microbrowser’s memory instead of making another request to the
server.
— When a new page is requested, the Microbrowser’s internal memory
is cleared and all components of the new page are downloaded from
the server.
Microbrowser User Interface
Two instances of the Microbrowser may run concurrently:
•
An instance with standard interactive user interface
SoundPoint IP 430
SoundPoint IP 650
SoundPoint IP 501
SoundStation IP 4000

•
An instance that does not support user input, but appears in a window on
the idle display
SoundPoint IP 430
SoundPoint IP 650
SoundPoint IP 501
SoundStation IP 4000
Launching the Microbrowser
The first time the Services key is pressed, the main Microbrowser loads the
homepage specified in the mb.main.homeconfiguration parameter.
Subsequent presses of the Services key simply toggle between the
Microbrowser and SIP telephony applications. The active page remains loaded
in memory when you toggle.
Whenever there is an event in the telephony application that requires the
user's attention, the telephony application is brought to the foreground
automatically.
The Microbrowser can be displayed again by simply pushing the Services key.
While the Microbrowser application is not displayed, it is still active and
pending transactions will complete in the background and be immediately
visible when the browser is brought to the foreground.
Navigation and Form Editing
The user navigates through pages by moving the focus among the focusable
items with the up and down arrow keys. Focusable items include links, form
elements, and buttons. The focus moves between all focusable items on a page
in the order that they appear in the XHTML source, including tables. For
newly displayed pages, the focus will automatically move to the first focusable
item visible on the current page.

Developer’s Guide SoundPoint IP / SoundStation IP
When the user has focused on a link that they would like to follow, or a form
element they would like to toggle, they press the Select key. This will either
generate a request for the linked page or toggle the selection of an element in
the form. When the focus moves to fields which are editable, the user may
simply enter text at will, then move the focus to the next selectable item when
complete using the up and down arrow keys. If there is a large area of the page
without a focusable element, the page is only scrolled by one screen for each
push of the arrow key.
To submit form data, navigate to and select a submit button on the page or
press the Submit soft key when available.
The Back soft key takes the user to the previous page viewed. The left arrow
key performs a similar function unless the user is editing a text field. The
Refresh and Home soft keys behave in the expected manner, reloading the
current page and returning to the user's home page respectively.
Text is entered into text boxes using the dial pad through the same entry
method used elsewhere on the phone. When editing text, a soft key allows the
user to cycle through uppercase letter, lowercase letter or numeric entry
modes. A Cancel soft key is available to undo the current edits.
Idle Display Microbrowser
The idle display Microbrowser is independent of the main Microbrowser, but
is capable of rendering the same content. Its homepage is configured via the
mb.idleDisplay.homeconfiguration parameter. The idle display
Microbrowser does not accept any user input and will only appear when the
user has no phone calls in progress and the phone is in the idle user interface
state. The idle display Microbrowser can update its content based on a
configurable refresh timer or by honoring the value of the Refresh header.
Developing an XHTML Application
Changing Configuration Parameters
You must modify the sip.cfg configuration file so that users will connect to
your application when they press the Services key (or select the Services
feature item).
To allow an application to be run from the Microbrowser:
1. Open the sip.cfg configuration file in an XML editor.
2. Locate the Microbrowser <mb> parameter.

3. Change mb.proxyto the address of the desired HTTP proxy to be used by
the Microbrowser.
For example, mb.proxy=10.11.32.103:8080
where 10.11.32.103 is proxy server IP address and 8080 is the port number.
4. Change mb.idleDisplay.hometo the URL used for Microbrowser idle
display home page.
For example,
5. Change mb.idleDisplay.refreshto the period in seconds between
refreshes of the idle display Microbrowser's content.
For example, mb.idleDisplay.refresh=10
6. Change mb.main.hometo the URL used for Microbrowser home page.
For example,
7. Change mb.limits.nodesto the maximum number of tags that the XML
parser will handle.
For example, mb.limits.nodes= 256
8. Change mb.limits.cacheto the maximum total size of objects
downloaded for each page (both XHTML and images).
For example, mb.limits.cache= 200
For more information on configuration parameters, refer to the SIP 2.1
Administrator’s Guide.
Sample Application
This section presents two sample applications that you can use as a starting
point for writing your own application.
To develop a static XHTML application:
1. Create a Sample.xhtmlpage with static information to be displayed.
In this case, the static information will be "Hello World!".
<html>
<head>
<title>Sample Application</title>
</head>
<body>
<p>HelloWorld!</p>
</body>
</html>

2. Configure the Web server to serve the above XHTML file.
For example, if you are using Apache Tomcat to try this example, then put
this file into the webapps\PLCM folder of Tomcat.
3. Configure SoundPoint IP and SoundStation IP phones to point to the
XHTML file in the sip.cfg configuration file.
For this example, change mb.main.home to
http://<WEBSERVER_ADDRESS:PORT>/PLCM/Sample.xhtml
.
4. Reboot the phones.
5. On a SoundPoint IP phone, press the Services (or Applications) key.
The text “Hello World!” appears on the graphic display.
To develop a dynamic XHTML application:
1. Create a AddStock.xhtmlpage.
This XHTML page is designed for getting a stock symbol as input from the
SoundPoint IP or SoundStation IP phone, then retrieve the information for
this stock symbol.
<html xmlns="http://www.w3.org/1999/xhtml">
<!- - HEADER START - ->
<head>
<title>Stocks</title>
</head>
<!- - HEADER END - ->
<!- - BODY START - ->
<body>
<!- - ADD STOCK FORM START - ->
<form method="POST" action="GetQuote.jsp">
<p>Symbol<input type="text" name="stockname"/>
<input type="submit" value="Get Quote"/></p>
</form>
<!- - ADD STOCK FORM END - ->
</body>
<!- - BODY END - ->
</html>
2. Configure the Web server to serve the above XHTML file.
For example, if you are using Apache Tomcat to try this example, put this
file into the webapps\PLCMfolder of Tomcat.
3. Write an application that is going to retrieve the stock information from a
data service provider.
For this example, this application will be retrieving stock information from
Yahoo and will send it to the Microbrowser. This application is written
using a Java Server Page (JSP).
