Installing SIP TAPI driver on Windows

By on Jan 28, 2013 in Blog, Phones, Support Blog

Some Windows applications (ie Outlook, CRMs) have a click-to-dial feature. Click on a contact’s phone number in Outlook and magically your phone starts ringing. When you pick up your phone, the phone automatically starts ringing the contact’s phone number you clicked on. With SIPTAPI, the click-to-dial feature can work on your Cloud Phone System. Basically, SIPTAPI is a TAPI driver  used to bridge between TAPI enabled Windows applications and the Cloud phone system. (like a print driver is used to use a printer)

*Contact us to make sure this feature is enabled on your phone system.


You can download siptapi for free from Sourceforge. The program is free to use, even for commercial purposes. You can find it on here:
