What is what does it mean when it says cancelled call?

A cancelled call simply means a call that was terminated before it was successfully connected to the intended recipient. It essentially indicates that the call did not go through. There are several reasons why a call might be cancelled. These can include:

• User Cancellation: The caller may have manually ended the call before it rang, for example, realizing they dialed the wrong number. (See: https://www.wikiwhat.page/kavramlar/User%20Cancellation)
• Network Issues: Problems with the phone network, such as congestion or technical faults, could prevent the call from connecting. (See: https://www.wikiwhat.page/kavramlar/Network%20Issues)
• Number Errors: If the dialed number is invalid, incomplete, or disconnected, the call will be cancelled. (See: https://www.wikiwhat.page/kavramlar/Number%20Errors)
• Recipient Availability: The recipient's phone may be out of service, switched off, or in a location with no network coverage. (See: https://www.wikiwhat.page/kavramlar/Recipient%20Availability)
• Call Screening/Blocking: The recipient may have blocked the caller's number or be using call screening features to prevent the call from connecting. (See: https://www.wikiwhat.page/kavramlar/Call%20Screening/Blocking)

Cancelled calls are generally not billed, although this depends on the specific terms of service with the phone provider. In a business context, a high rate of cancelled calls could indicate problems with a telephone system, data quality, or customer service strategies.
