MSPS: Distinctive Ringing Does Not Work Properly with Call Manager

ID: q230333

The information in this article applies to:

Microsoft Cordless Phone System version 1.0

SYMPTOMS

When you attempt to use your telephone company's distinctive ringing service with Microsoft Call Manager, Call Manager may not recognize the ring type assigned to fax or data calls.

CAUSE

This behavior can occur if the Value Data of the VoiceProfile value is incorrect in the Microsoft Windows registry.

RESOLUTION

IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

To resolve this issue, edit the VoiceProfile value in the following registry key


   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Class\ 
   Modem\<nnnn>

where <nnnn> is a four-digit number representing the Microsoft Voice Only Software Modem.

Modify the value data of the VoiceProfile value to 27 22 01 F8.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft Cordless Phone System version 1.0.
