Distinctive Ring Is Not Supported by Windows 2000 Fax

  • Microsoft Windows 2000 Server

  • Microsoft Windows 2000 Datacenter Server
This article was previously published under Q272943


Windows 2000 Fax does not support the distinctive ring feature. Because of this, Windows 2000 Fax cannot distinguish calls for distinct numbers if the phone line is enabled with distinctive ring.


This problem occurs because the Windows 2000 implementation of UNIMODEM in TAPI does not support the distinctive ring feature.


To work around this problem, use any of the following methods:
  • Obtain and install a third-party device to provide support for distinctive ring feature. We suggest the SR Series from Multi-Link. This product is available online at http://www.faxswitch.com/sr_next.html or http://www.faxswitch.com/sr.html
  • Use an operating system that supports the distinctive ring feature such as Microsoft Windows 98 Second Edition or Microsoft Windows Millennium Edition (Me).


Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
