ISDN Caller Id

ISDN Caller ID refers to the feature of the Integrated Services Digital Network (ISDN) that allows the caller's phone number to be displayed on the receiving end.

When a call is made over an ISDN line, the telephone exchange sends the calling party's phone number to the receiving end, where it is displayed as Caller ID information.

ISDN Caller ID availability varies by country and telecommunications provider. It is best to check with your service provider if this feature is supported in your area.

Yes, you can usually enable or disable the presentation of your Caller ID on an ISDN line. Contact your service provider to learn about the options available and how to configure it.

To receive ISDN Caller ID, you need a compatible device that supports this feature. This could be an ISDN phone, ISDN terminal adapter, or a compatible ISDN-enabled device connected to your system.

ISDN Caller ID is usually included as part of your ISDN service plan. However, it's always a good idea to confirm with your service provider if any additional fees or subscriptions are required.

The ability to log past calls with ISDN Caller ID depends on the capabilities of your ISDN device or telephone system. Some devices may offer call history features, but it's not a standard feature of ISDN itself.

ISDN Caller ID is specific to ISDN lines and devices that support ISDN protocols. Analog phones or devices not designed for ISDN might not be able to interpret or display ISDN Caller ID information.

The format in which ISDN Caller ID is displayed can be determined by the receiving device or application. However, this customization is usually limited to the options provided by the specific device or software.

ISDN Caller ID functionality may be affected during power outages if the devices involved, such as the telephone exchange or related equipment, are dependent on electricity. It's advisable to check with your service provider about their backup solutions.
