ITP Keyphone with Remote NAT Router Addressing

Figure 11a shows Private with Public connectivity using a router supporting
reservations or port forwarding at the OfficeServ 7100 end and a NAT supporting router
at the remote ITP endpoint. In public network cases a public IP addresses must be
obtained for the MP10/MP10a and the MGI card(s). A static public IP address OR a
DHCP address can be obtained for the remote ITP keyphone(s) location(s). The ITP
keyphones can also acquire an IP address from the NAT/DHCP router so that they may
match the IP addressing scheme of the network where they are located. When using
the routers' NAT feature multiple ITP keyphones can register to the MP10/MP10a.
Figure 11b also shows remote ITP keyphones using a NAT router. This approach is
extremely cost effective due to the ITP and LAN PC's using the same public address.
The ITP's use the public address to reach the OfficeServ 7100 system and the LAN
PC's use the public address to access the Internet
