I have an NEC Aspire system and I need to change the number of rings before the Automated Attendant answers the outside line. It's supposed to be '22-01-04 Normal DIL Incoming Call No Answer Time' under 'System Data' on the web interface, but for some reason I don't have a 22-01-04. The settings on my system are labeled 22-XX instead of 22-XX-XX.
