Can’t Call Exchange UM Auto Attendant from OCS

by Jamie Schwinn on June 17, 2010

I ran into an issue trying to call a new Exchange UM Auto Attendant from OCS today. Calls to the AA’s DID kept failing and the only error in the OCS Log (Snooper) was “The application specified an invalid request-uri”. The issue ended up being a problem with the name of the Exchange UM Auto Attendant. The Auto Attendant must be created without any spaces in the name. To fix the issue, delete the Auto Attendant and the associated OCS Contact object, recreate the Auto Attendant with no spaces in the name, e.g. “My Auto Attendant” -> “MyAutoAttendant”, and then rerun OCSUmUtil.exe and recreate the contact object.
