Steven Goldmann is directly responsible for setting up all our communications systems; VOIP Phone, Call Managers, Network switches, Routers, Servers, and many other devices. The Army uses Cisco Protocol Network (CPN) telephone systems, again requiring a communications specialist with a strong understanding of Active Directory call manager. Our S-6 was able to manipulate individual telephone functions using necessary keystrokes on the phone keypads. He also conducted multiple telephone number migrations on his own, and in all cases managed more than one telephone network simultaneously.
