Source note · Enabling mixed mode and encrypted calling in Unified CM
utils ctl reset localkey, run on the publisher, regenerates the CTL file signed with the CallManager key (secondary SAST role) for use when the ITLRecovery certificate has changed and endpoints are locked out; once endpoints have that file, the CTL update command is run again to re-sign it with ITLRecovery.
