I have a UC520 with a B-ACD group configured with CCA 2.2.1. When you call the pilot, you receive dead air then a busy signal after a bit. I've done some debugging, and the correct dial-peer is being reached. What debug commands can I use to get more information? I have deleted the entire B-ACD config from CCA and removed the scripts in flash. I also cleaned up the config by hand because CCA left a couple of ephone-dns behind. After cleaning, I rebooted, and then configured from scratch. CCA uploaded the scripts first of couse. Still didn't help.
