About caller ID
The caller ID with call waiting features in this telephone lets you see the name and telephone number
of the caller before answering the call, even when you’re already on a call. These features require
services provided by your local telephone company.
Contact your telephone company if:
• You have both caller ID and call waiting, but as separate services (you may need combined
service),
• You have only caller ID service, or only call waiting service, or
• You do not subscribe to any caller ID or call waiting services but wish to try these services.
You can use this telephone with regular caller ID service, and you can use its other features without
subscribing to either caller ID or combined caller ID with call waiting service. There may be fees for
these services, and they may not be available in all areas.
The caller ID features will work only if both you and the caller are in areas offering caller ID service,
and if both telephone companies use compatible equipment.
Voicemail service
If you subscribe to voicemail service provided by your telephone company, you can receive voicemail
left by the caller. When you have new voicemail, the handset will display NEW VOICE MAIL .
