Links

As of Release 1.8, the 4630/4630SW IP Telephones support dialing from hyperlinks. To dial from a link, a given link’s href attribute value must of the form tel:nnnnn or javascript:dial(‘nnnnn’). Selecting that link passes the characters nnnnn to the 4630/4630SW Phone application for direct dialing.

Hyperlinks are the heart of the Web browser’s power. The link allows the user to:

• click text or an image to jump to another Web site,
• click text or an image to jump to another page within this site, or
• click text or an image to jump to another area on a page.

Although URLs allow you to use various protocols, use only HTTP and HTTPS for the 4630 IP Telephone Web Browser.

• <a> specifies the full or relative URL for a hyperlink. When using the target attribute, never use the _blank name. 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 becomes confused and a reboot is 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 is set in the <a> tag, the <base> tag value is ignored.

Using 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 can cause the browser software to create a new window that is outside the Web Access Application's control.
