Telify, an extension for the Thunderbird email client and Mozilla Firefox web browser, turns phone numbers in emails and on web pages into clickable links that opens supported voice applications when clicked on to make the whole process comfortable.

All it takes is to click on the phone number to initiate that call directly from within the application you are working in.

The extension will load the appropriate voice communication software which will make the call automatically by default.

The preferences offer options to select one of the supported protocols. Available for selection are skype:, tel:, callto:, sip: and a custom url protocol.

Please note that applications may share protocols and that it may depend on which program is installed or the default one on the system for the links to work properly.

It is furthermore possible to configure the extension to dial directly if a country code is present or open a menu instead. The menu is always displayed if no country code is present.

Additional options include the configuration of text highlighting from the default light highlighting to none, medium or strong, if your country code should be suppressed, if + should be replaced in phone numbers and how many numbers of recently used country codes should be displayed.

The extension processes each page or email and turns any phone number that matches the supported formats into a clickable link based on the user's preferences.

Since it processes all pages, it may slow down page loading time somewhat.

A left-click on a phone number that has been turned into a link opens a selection menu which offers choices to call that number. The very same options are also available on right-click. A middle-click on the other hand bypasses the menu and calls the phone number directly in the default application for that protocol.

Some users have reported compatibility issues between the extension and the Gmail website which I cannot confirm. The extension worked fine there as well.

Telify is available for both the Thunderbird email client and the Mozilla Firefox web browser.

    On Linux, I found that telify would open skype, but not actually place the call.
    This is because the default association was to “skype”, found as a script, /usr/bin/skype
    I changed the association to /usr/bin/skype-bin and now it places calls.
