About caller ID

This product supports caller ID services offered by most telephone service providers. Caller ID allows you to see the name, number, date and time of calls. The available caller ID information will appear after the first or second ring.

Information about caller ID with call waiting

Caller ID with call waiting lets you see the name and telephone number of the caller before answering the call, even while on another call.

It may be necessary to change your telephone service to use this feature. Contact your telephone service provider if:

You have both caller ID and call waiting, but as separate services (you may
need to combine these services).
You have only caller ID service, or only call waiting service.
You don’t subscribe to caller ID or call waiting services.

There are fees for caller ID services. In addition, services may not be available in all areas.

This product can provide information only if both you and the caller are in areas offering caller ID service and if both telephone service providers use compatible equipment. The time and date, along with the call information, are from the telephone service provider.

Caller ID information may not be available for every incoming call. Callers may intentionally block their names and/or telephone numbers. You can only view and store a maximum of 15 digits or characters of every caller ID log entry.

NOTE: You can use this product with regular caller ID service, or you can use this product’s other features without subscribing to caller ID or combined caller ID with call waiting service.

Caller ID history

How the caller ID history (caller ID log) works

The telephone stores caller ID information about the last 50 incoming calls. Entries are stored in reverse chronological order. The phone deletes the oldest entry when the log is full to make room for new calls. If you answer a call before the information appears on the screen, it does not show in the caller ID history

Missed (new) call indicator

When the telephone is in idle mode and has new or missed calls, its screen shows XX Missed calls.

All new and missed entries are counted as missed calls. Each time you review a new caller ID log entry (indicated by the NEW icon on the screen), the number of missed calls decreases by one.

Caller ID operation

Memory match

If the incoming telephone number matches the last seven digits of a telephone number in your directory, the name that appears on the screen matches the corresponding name in your directory.

For example, if Christine Smith calls, her name appears as CHRIS if this is how you entered it into your directory

NOTE: The number shown in the caller ID log will be in the format sent by the telephone service provider. The telephone service provider usually delivers 10-digit phone numbers (area code plus telephone number). If the telephone number of the caller does not match a number in your directory, the name will appear as it is delivered by the telephone service provider.

Troubleshooting

If you have difficulty with your telephone, please try the following suggestions. For Customer Service, visit our website at www.telephones.att.com or call 1800-222-3111. In Canada, dial 1866-288-4268.

My telephone doesn’t work at all.

Make sure the power cord is securely plugged in.
Make sure you plug the telephone line cord securely and firmly into the telephone and the telephone wall jack.
Reset the telephone. Unplug the electrical power. Wait for approximately 15 seconds, then plug it back in. Allow up to one minute for the telephone to reset.

The display shows No line. I cannot get a dial tone.

Try all the suggestions, as mentioned above.
If the previous suggestions do not work, disconnect the telephone line cord from your telephone and connect the telephone line cord to another telephone.
If there is no dial tone on that other telephone either, your telephone line cord may be defective. Install a new telephone line cord.
If changing the telephone line cord does not help, the wall jack (or the wiring to this wall jack) may be defective. Try using a different wall jack in your home to connect your CL4940/CD4930 telephone, or contact your telephone service provider (charges may apply).

I cannot dial out.

Try all the suggestions, as mentioned above.
Make sure you have a dial tone before dialing.
Eliminate any background noise. Noise from a television, radio or other appliance may cause the phone to not dial out properly. If you cannot eliminate the background noise, first try muting the telephone before dialing, or dialing from another room with less background noise.
If other phones in your home are having the same problem, contact your telephone service provider (charges may apply).

I hear other calls while using my phone.

Disconnect the telephone from the telephone jack, and plug in a different telephone. If you still hear other calls, call your telephone service provider.

System announces, “Time and day not set.”

You need to set the system clock (page 10).

Troubleshooting

I get noise or static when I use the telephone base.

If you subscribe to high-speed Internet service (DSL – digital subscriber line) through your telephone line, you must install a DSL filter between the telephone line cord and the telephone wall jack (page 4). The filter prevents noise and caller ID problems as a result of DSL interference. Please contact your DSL service provider for more information about DSL filters.
Do not install this phone near a microwave oven or on the same electrical outlet. You may experience decreased performance while the microwave oven is operating.
If you plug your phone in with a modem or a surge protector, plug the phone (or modem/surge protector) into a different location. If this does not solve the problem, relocate your phone or modem farther apart from one another, or use a different surge protector.
If other phones in your home are having the same problem, contact your telephone service provider (charges may apply).

My caller ID isn’t working.

Caller ID is a subscription service. You must subscribe to this service from your telephone service provider for this feature to work on your phone.
The call may not be calling from an area that supports caller ID.
Both your and your caller’s telephone service providers must use caller ID compatible equipment.
If you subscribe to high-speed Internet service (DSL – digital subscriber line) through your telephone line, you must install a DSL filter between the telephone line cord and the telephone wall jack (page 4). The filter prevents noise and caller ID problems resulting from DSL interference. Please contact your DSL service provider for more information about DSL filters.

System does not receive caller ID when on a call.

Make sure you subscribe to caller ID with call waiting features from your telephone service provider. Caller ID features works only if both you and the caller are in areas offering caller ID service, and if both telephone service providers use compatible equipment.

Incomplete messages.

If a caller leaves a very long message, part of it may be lost when the system disconnects the call after the recordings exceed the maximum recording time (page 39).
If the caller pauses for longer than three seconds, the system stops recording and disconnects the call.
