I am trying to set up a new BCM50's auto-attendant, which we have upgraded from a previous CallPilot 100. The greeting tables and CCR tree has been set up as it is supposed to, the company greetings are recorded, and the lines are set to be answered by the AA. However, when I try to call in, all I get is a click and a second dial tone. None of the greetings are played and the dial tone I hear seems to be an intercom tone. Any suggestions on what might be missing from the setup?
