SL1000/SL1100
• An attempt to Voice Over a station can be denied if the station is in DND (Do Not Disturb) Mode,
Automatic Redial is activated, during Station Programming, during Incoming Ringing, during
Internal/External Paging, during a Conference Call, during a conference call on hold, the terminal is
on internal hold, or the terminal has a call on internal hold.
• When a Single Line Terminal is on a call and Voice Over is presented, the Single Line Terminal
cannot talk back to the party that originated the Voice Over.
• Voice Over to a Single Line Terminal is not recommended because cross talk is inherent in the side
tone of analog telephones.
• Voice Over to a user on Speaker phone is not recommended because the conversation may be
heard by the outside party.
• Answering a Voice Over requires a uniquely programmed Voice Over key.
