on the phone to answer your call. The called extension user hears a Call Waiting tone and is
able to answer the call.

the caller will hear ringback tone.
• If the called party has been set to activate the Off-Hook Call Announcement (OHCA) or
Whisper OHCA function, the caller can announce the call through the speaker or the
handset.
