1.2 Network Devices and Numbering Plan

1.2.2 Numbering Plan Example
There are 2 methods to plan your numbering system, as follows:
This section provides a network numbering mechanism using the PBX code method based on the
previous example diagram. Configure your network referring to this example.
Note
An example using the extension number method is provided in "B Alternative Numbering Plan
Example".
IP Addressing Information
IP addressing information is typically supplied by a network administrator. Consult your network
administrator for specific values.
PBX code
method
In addition to the destination number, the caller dials the unique PBX code of the
PBX to which the called party is connected. Therefore, extension numbers at
separate PBXs in the network can overlap. For example, each PBX in the
network can have an extension whose number is 201.
Extension
number method
The caller dials only the destination number of the called party to call through
PBXs at different locations (hence there are fewer digits to dial than with the PBX
code method). To employ the extension number method, no 2 PBXs can have
extensions sharing the same number. For example, if one PBX in the network
has an extension whose number is 201, no other PBX can have an extension
with the same number (201).

Description
Card IP Address 200.45.11.35 199.176.64.41
Identifies the location of each VoIP Gateway
Card in the network during VoIP
communications. A unique IP address must
be assigned to each card.
Default Gateway
Address
200.45.11.1 199.176.64.1
Identifies the IP address of the primary
gateway (typically a router or similar device)
that exchanges IP packets with the other
gateways on the VoIP network.
Subnet Mask
Address
255.255.255.0 255.255.255.0
Defines which digits of an IP address are
used for the network address and the host
address at each network location. A card IP
address must fall within the same subnet as
that of the default gateway (e.g., router) that
is connected to the card.
