ActivaTSP with Outlook and Device&User mode

Dear folks,

I’ve been asked whether it is possible to use Outlook’s “Call” feature in the contact view with Asterisk (v11, Freepbx 2.11).
To that end I found the ActivaTSP TAPI driver, which seems to work well in this scenario according to other user’s accounts.
However, we are operating in hotdesking (device & user) mode, so when someone logs on to the computer, the ActivaTSP driver would somehow have to log on as that agent (with the extension and PIN code).
Has anyone had any experience with this?
