An Exchange Server 2007 Unified Messaging user cannot play a voice mail if the caller-id of the external caller contains a wildcard character

Symptoms

Consider the following scenario:
  • User A is a Microsoft Exchange Server 2007 Unified Messaging user.
  • An external caller calls User A and leaves a voice mail.
  • The caller-id of the external caller contains a wildcard (*) character.
In this scenario, User A finds the following results:
  • When User A logs into Outlook Voice Access and then tries to play the voice mail, there is nothing. Or, User A receives the following error message:

    Message cannot be read.
  • User A cannot play the voice mail by using the Play on Phone feature in Microsoft Office Outlook.
  • User A cannot press the Play button of Windows Media Player for the voice mail in Outlook and in Outlook Web Access.
Note Certain third-party gateways add a wildcard character to the caller-id of the external caller.

Cause

This problem occurs because the caller-id of the external caller is used for the voice mail file name. However, wildcard characters are invalid for file names.
