•

Voice Calling: Extension calls are connected immediately, without a ringing tone.

•

Tone Calling: A ringing tone is sent to the called extension.

Extension Class of Service (COS) programming determines whether the default for the originating 

extension is voice or tone calling. Regardless of the default, you can toggle between voice or tone 

calling by entering the Tone-Voice Call feature code. For example, if the extension default is tone 

calling, you can make a voice call to another extension by entering the Tone-Voice Call feature access 

code.
