Need help trying to setup Officeserv 7200 replacing the Isdn card with an 8trunk card. The Samsung system is thrown out from a discontinued business. How do I go about to reprogram the whole system? I m setting up for a local nusery school 9 stations only.

You need to get in contact with a local vendor so that they can reset the password for you. The person that had been working on it changed the tech password. Dealers can reset it using a backdoor. If you have no knowledge in the setup, it's best you call them so that they can assist you in programming it so it will function to the nursery's needs.
