The power went out recently at my office and I had to reprogram the entire phone system. I have been able to solve everything except:

I can't get the phones to pick up other calls. In other words, I have the incoming lines all set in a Line pool "Pool A" And all the phone sets are configured to have access to pool A. But when the phone rings at a workstation and I want to pick up the call, I keeps giving me an error tone and says "Pickup Denied" What am I doing wrong? What do I need to change in Admin to solve this riddle? Thanks
