I am having problems with trunk lines 1 and 5 not going to the auto attendant. they have a total of 7 CO lines the rest of them seem to be working properly. I have checked everything i can think of. they are still in the right groups, all the settings seems to be correct. I have replaced the CO card and the SLI card. the auto attendant system is working properly. It started acting a little funny about 2 months ago, i had to clear the memory cache on the voice mail about once a week. anyone have any suggestions?
