We are installing the TAPI driver for IP Office on our clients' PC's, and we are running into a slight issue. The installation goes fine, and we can configure the driver under 'Phone and Modem Options' in the control panel to point to the IP address of the control unit and the correct user name. However, when I go into Window's phone dialer, go to Options under the Edit Menu, then go to change the "Line Used For Phone Calls", it does not have the option "IP Office Phone: {extension #}" like it should. I have tested it in my office, and it worked fine. I was able to choose that option in phone dialer, and was able to make phone calls. We are using 2.1.248901, and the PC's are running Windows 2000. Any suggestions?
