I have a 3825 with CME4.02 that will not allow me to establish conference calls. After I connect to one person and press Confrn, the phone displays "No Line Available". I have max-conferences 12 gain -6 set.
Either congigure the DN on the phone as a dual-line DN using a command such as "ephone-dn 1 dual-line" or configure more than one DN on the phone. This is necessary for the phone to dial the second number while the first call is still connected.
Hope this helps. If so, please rate the post.
