Links; Frames - Avaya 4600 Series Administrator's Manual

Creating Web sites for the 4630/4630SW IP Telephone
Browser Features and Behavior

Links

As of Release 1.8, the 4630/4630SW IP Telephones support dialing from hyperlinks. Specifically, if the
value of the HREF attribute for a given link is of the form tel:nnnnn or javascript:dial('nnnnn'), when
that link is selected, the characters nnnnn are passed to the 4630/4630SW Phone application for direct
dialing.
Hyperlinks are the heart of the web browser's power. The link is what allows the user to click on some
text or an image to jump to another web site, another page within this site, or another area in this page.
Although URLs allow various protocols to be used, only http and https should be used for the 4630 IP
Telephone Web Browser.
•
<a> specifies the full or relative URL for a hyperlink. When using the target attribute, the _blank
name should never be used. With the exception of frames, the 4630 IP Telephone Web Browser is
not intended to be a multi-window browser. Thus, if a page attempts to reference a new, non-
frame window, the browser will become confused and a reboot will be necessary.
•
<base> defines the default target to be used in all <a> tags. This is done by setting the target
attribute of the <base> tag. If the target attribute has been set in the <a> tag, the <base> tag value
is ignored.
The use of the target attribute with the Web Access Application is strongly discouraged because the
application supports a single window for browsing. The use of the target attribute may cause the browser
software to create a new window that is outside of the Web Access Application's control.

Frames

Frames allow multiple windows to be created on the browser's base window. The browser is effectively
split up into multiple areas. Each frame may be given a name or ID. Using the target attribute of the <a>
tag, a web page may be displayed in another frame.
Although frames behave as defined, the small size of the screen makes them impractical to use. Just like
tables, frames take up too much room on the display. One could, though, take advantage of frames by
having a small "table of contents" frame with images for links. In general, however, use of frames is
strongly discouraged.
•
<frameset> defines an area for a set of frames.
•
<frame> defines a single frame in a frameset.
•
<iframe> defines an in-line frame. More detail
•
<noframes> provides a fallback for browsers that don't handle frames. If the designer intends to
use frames and make these pages available to phone, this tag should certainly be employed.
