Does anybody know how to default or reset the Installer Level Passord on a Mitel SX200EL. This system was handed over to us by the end user (customer) for service and maintenance from the old vendor. The Customer had provided us with passowrds from the old vendor and told not to change the Password. Now we are locked out and need to reset the Password. Mitel will do this for alot of $$$ , which is outragous. Can anyone Help. Thanks!
