This is whats going on here. I got on site today for the first time due to ice storm that came in on Thursday and Friday. After programing all 23 trunks on line keys I was able to dup the problem about every tenth call with no light on the incoming trunk. I was able to press trunk 1 and answer myself even though it did not ring or light up. Worked with Vertical tech suport and we are going to upgrade the switch from F19 to F20, the PRI firmware from F05 to G05 and add the dx-80 hex file to the voice mail. All file have been downloaded and once the firmware gets here I will find out if this is the fix. I have been in direct contact with Mike and it sounds like his troubles are gone. NuVox is our local on this project and they say its not them and they have done a ton of testing. I will get back after the upgrades that will take place next week.
