6. In the Command Prompt Window, Type arp –a and Press Enter.

This will display all of the IP Addresses currently in use on your Network.

Locate the Last DYNAMIC IP Address and create two (2) brand new IP Addresses that

immediately follow after that number. The first number will be used for the VoIP Card and the

second number will be reserved for Voice Ports (such as SIP Trunks).

Here's an Example:

In the example picture above, the Last DYNAMIC IP Address is 192.168.1.

so our two new IP Addresses would be:

VOIP CARD: 192.168.1.

VOICE PORTS: 192.168.1.

Based on YOUR Last DYNAMIC IP Address, write your new IP Addresses here:

VOIP CARD:

VOICE PORTS:

8. Again, if you have an IT Administrator, it is important to confirm with them that your two (2) new

addresses are available for use on your phone system and will not interfere with any other

devices on your network.
