I wrote an Outlook AddIn that integrates with ET. It doesn't use TAPI (which I think might be an anagram for PITA) :-) Rather, it uses ET's command line-based IPC. It dynamically creates a "split button" control in the contact editor window (aka, inspector) with a drop-down menu, one item for each phone number stored in the contact. For Outlook 2010 and newer, it also creates the identical element in the context menu when you right-click a contact item in a list. (See screen cap below.)
It support Outlook 2007 and newer. Before dialing it strips any formatting characters, and if the first digit isn't "1" it prefixes the number automatically. (I realize this will break international calls -- I'm thinking I'll add a checkbox to the ribbon to make it easy to enable/disable, and possibly even persisting that preference per-contact (in a UserProperty.)
The working name at the moment is ExpressTalkDialer, but that may change (if NCH views this as a trademark infringement.) If anyone is interested, please post here. I should have something ready to go in a few weeks.
