Under normal circumstances, the Deployment Service (DLS) contacts the IP terminals via their IP address when a job has been created. In our remote office case, however, the IP terminals are located in the Internet, as it were behind a NAT router with a local IP address, which means that the DLS cannot reach them. The DLS and IP terminals support a proprietary solution in this case, which allows administration of IP terminals behind a NAT router. This solution is called DLS Contact-Me Proxy (DCMP). Communication is always opened by the IP terminal in this solution.
