I have a BCM 400 upgraded from 3.7 to 4.0 2 years ago, Company implemented 66 IP phones 6 months ago, I have been plaqued with problems since. 58 phones registered and 48 can 4 digit dial across network, the rest cannot. Delete those phones and reprogram and still cant dial. These 10 in Monitor grab Voip trunk and on 4th digit I see it hang up and grab the next trunk up and get reorder tone. Compare UIP log with phones that can call and they are the same. I suspected Data corruption on the Drive. I tried to do a cold reset and it goes through the motions and reboots but comes back with the same ext's and gateways and routes and dest in tact. BCM50 can do a level II reset, is the a way to do a level II on the 400. I also checked BFT and its good
