Abstract: Call blockages can now be identified down to the line and group of lines that caused the call blockage. No more long statistical studies followed by guessing in order to alleviate blockages. This method and apparatus operating in concert with recently added load balancing processes report specifically what caused each call blockage at what time. With such specific information, each line or group of lines that needs to be moved or added to a new line terminating equipment are quickly identified and accomplished, thereby keeping service to the average customers at acceptable levels. The amount of specificity represents a breakthrough in call line and traffic management.
