Exchange UM Auto Attendant cannot transfer calls to a phone or extension number in Skype for Business Server 2015

View products that this article applies to.

Consider the following scenario:
  • You upgrade to or install Microsoft Skype for Business Server 2015.
  • Your Exchange Unified Messaging (UM) Auto Attendant (AA) contact is hosted on a Skype for Business Enterprise Edition Pool or Standard Edition server.
  • An incoming PSTN (external caller) call reaches the UM Auto Attendant and is blind transferred to a Skype for Business user or to an RGS that does not have a dedicated DID number.
In this scenario, the call fails, and your Gateway server may generate a 404 error message. The calling party may also hear the following announcement from the AA:

"Call cannot be transferred, returning to the main menu."
Internal Lync users can still successfully transfer calls to the user or RGS.
