The Telephony MMC snap-in crashes in Windows Server 2008 or in Windows Server 2008 R2 when you edit users for a line device

Symptoms

Consider the following scenario:

  • You have a computer that is running Windows Server 2008 or Windows Server 2008 R2.

  • You select a line device under a telephony service provider in the Telephony Microsoft Management Console (MMC) snap-in (Tapimgmt.msc).

  • You try to add a user for the line device.

In this scenario, the Telephony MMC snap-in crashes.

Cause

This issue occurs because the Telephony MMC snap-in uses a wrong buffer length to copy data to memory. This makes some memory data invalid. The Telephony MMC snap-in crashes when the invalid data is accessed.
