APPLIES TO

  • Microsoft Windows 2000 Server



SYMPTOMS

Telephony API (TAPI)-based applications may stop responding in a Microsoft Windows Server 2000-based telephony server. Additionally, you cannot disconnect telephone calls even though the remote party has disconnected.

This problem occurs if the following conditions are true:

  • A telephone call is being disconnected.
  • The server is located in a large telephony server call center.
  • The telephony server has more than one CPU.


CAUSE

This problem occurs because of a deadlock condition between the lineClose function call and the lineDeallocateCall function call.
