IVX 128 Plus: additional features
Function 82: Local IP PBX programming
Function 82 is an Administrator-level function used to program the local IP PBX so that it can
communicate with the phones on its own network segment ("local phones"), with Remote IP Feature
Phones, and with other IP PBXs. The administrator will be able to:
• Assign IP addresses and UDP ports to the IP PBX and the local IP phones
• Set limits to the number of available remote talk paths
• Set up the pool of IP addresses used by local IP phones
Function 821: Program IP PBX addresses
Assign IP address to the IP PBX
The administrator assigns an IP address to the IP PBX, using four-octet (dotted-quad) notation. The
default is 192.168.248.1. Press # for the periods between the octets. Press # again when finished.
PBX PRIVATE IP
192.168.248.1
Normally, the IP PBXs will use private IP subnetworks (as defined in RFC 1597
public subnetworks. For simplicity's sake, it is a good idea to keep all the IP PBX's components within
the same address range. If the administrator chooses to do this, it would again be a good idea to assign
to the IP PBX the first available address in the range. For example, if the user plans to use the IP
addresses 192.168.210.1 through 192.168.210.97 as the range of IP addresses, the .1 address would
usually be assigned to the IP PBX, with the remainder of that block being made available to the phones.
Important: The IP PBX's MAC address will appear in the display. Write down this address. It is
needed for programming Esi-Link access to this IP PBX from other locations.
Enter gateway's IP address
Although it can use a public IP address, the IP PBX will normally use private addressing and sit behind
some sort of address-translation device, such as a NAT
public IP address to the network on which the IP PBX resides is the gateway. This device's address is
often called the default gateway address. For instance: a company's Dallas office uses DSL as its
broadband connection, and the DSL line is terminated at a DSL router that sits on the LAN. That router
will have two interfaces: the WAN side, which must have a public (globally-addressable) IP address,
and the LAN side, which normally has a private (non-routable) IP address. The private IP address on the
LAN interface is the address that is used in this programming step.
Note: The IP addresses of the IP PBX and the LAN interface do not necessarily have to be on the
same subnet.
Enter the IP address of the gateway's LAN interface in dotted-quad notation, using the # key as the dot
between the octets. Press # again when finished.
