4.3.2 NUMBERING PLANS DATA — PGM 102 to 109
4.3.2.1 System IP Address Plan — PGM 102
The System IP Address Plan sets several IP addresses, including the KSU LAN port IP address (MPB IP
Address) required for external VoIP calls, the IP address for the router, and the system‘s internal private IP
address Plan. Note that the MPB and Router addresses and sub-net masks must be routable IP addresses for
access to an external VoIP network, remote access by a gateway/board or terminal, and remote Web access.
The VOIB must also have a routable IP address for access to/from an external VoIP network or remote user.
When Automatic IP Assignment, button 7, is enabled, the system will assign IP addresses to each local
terminal and the VOIB using the assigned System IP address range. These addresses are used for
communications between the system and the VOIB and terminals. The system may be connected to a LAN
that is segmented by two separate private IP address schemes. This segmenting technique is often used to
separate voice and data devices. However, with this segmenting technique, the system would normally treat
the segmented Terminals, such as iPECS Soft Phones, as remote devices, using valuable WAN bandwidth.
Assigning the “Second Sys IP address” with a valid IP address from the second segment permits the system
to communicate with the devices directly over the LAN.iPECS can be installed behind a NAPT server if the
NAPT server provides fixed address translation and port forwarding to the system. In this case, the system will
employ the “Firewall IP address,” button 10, as the fixed public IP address for communication with remote
devices. This address must be assigned as the “MPB” address in the remote device.
