• The notification receiving methods (call waiting tone, OHCA, and Whisper OHCA) are available when
the called extension is having a conversation with another party. If the extension is not having a
conversation but is unavailable to receive the notification (dialing a number, for example), the calling
extension will be kept waiting until the called extension becomes available. Even while waiting, the
calling extension will hear a ringback tone.
• If none of these methods of receiving notification (call waiting tone, OHCA, or Whisper OHCA) are set
at the called party, the caller will hear a reorder tone after trying to send a call waiting notification.
