Initiating call from the computer
Microsoft Windows offers a TAPI interface that provides telephony services for applications wishing to use it. SIPTAPI is a free TAPI application driver that enables you to use your SIP account for the purpose of initiating a call from your computer. This will for example allow you to call a contact number in the MS Outlook address book.

After pressing the dial button the PBX calls your phone and once you pick it up it calls the destination number.

To set it up you will need to have your telephone extension number and the password.

First you will need to download SIPTAPI:

After unziping, move the siptapi.tsp file to your %SystemRoot%/System32 folder (for example C:\WINDOWS\System32 in XP).
