Consider the following scenario:
- You set up a Microsoft Office Communications Server 2007 R2, Response Group service to forward an incoming call when there are no members in the group to answer the call.
- The number that the call is forwarded to is a Public Switched Telephone Network (PSTN) number.
- You call this Response Group by using Office Communicator.
- No member in the group answers your call.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
