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.
