The Mailbox server isn't configured to receive fax messages on "%1". The fax call to this number that originated from phone number "%2" has been disconnected. To resolve this issue, ensure that the person or system transmitting the fax is sending to a number associated with a UM-enabled mailbox. If this warning is repeated, you may need to contact the sender or block calls from that number.
