Kevin thanks for responding. There are a total of six different hunt groups, some are broadcast and some are sequential. It's not one group that is having this problem it happens to all of them. It seems to me that something is going on with a call to the phone or two calls from different groups to the same phone is causing these phones to drop out of the hunt group, they do use the dnd feature but if it's turned off on the phone, and the phone is already kicked out, the call will skip that phone, even though it still shows in programming that the phone is still in the group.
