The Allow Last Digit Repeat function permits a repeated last digit of an ESDN to terminate the call immediately, similar to pressing the octothorpe (#) key. This prevents an ESA call from being dropped if the last ESDN digit is accidentally dialed again, but also processes the call immediately, rather than allowing an extended pause waiting for an additional digit.
