Frequently Asked Questions
What is 'Calling Line Identifier' (CLI)?
Calling Line Identifier (CLI) is an option provided by most telecommunication service providers. This option allows your phone to display the number and/or name (caller ID) of the caller who calls you.
In most cases, a small monthly fee is needed for CLI/Caller ID subscription. If the handset(s) and base station are of different models, CLI may not work correctly.
