We have a Mitel SX200 phone system and recently repaired the VM system. When we tried to go in and program it to connect to the VM lines we relized that we are unable to access the applications menu. The main console will not allow to access the applications. I am not all that secure with the phone guys skills cause he always wants to "reinstall everything" and "reprogram." He says he has tried to connect through the RS-232 cable with a laptop, have restarted the entire system and still no luck. Its as if the system has locked us out. Can anyone help us. We are in dire need of a professional opinion.
