Value Definition
400 SAF_BAD_REQUEST – SAF Forwarder was unable to accept the request due to incorrect syntax (malformed), missing required attributes, and other similar reasons. Investigate the configuration between the SAF Forwarder and Unified CM to be certain that all settings are correct for your deployment. In particular, check the Client Label configured on the router to make certain that it matches the Client Label configured in Cisco Unified CM Administration on the SAF Forwarder Configuration window (SAF > SAF Forwarder).
