# Camp-on Tone Security

Camp-on Tone Security is a Class of Service option that suppresses the application of Camp-on tone. If any party in a call has this option enabled, no Camp-on tone is returned to anyone in the call.

Ports connected to fax machines and trunks (except IP trunks) used for fax calls should have this option and the Override Security option enabled in their COS.
