Note that the received caller information may not be displayed on telephones or wireless phones connected
to SLT ports.

• 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.
