Application Note – LAN Configuration Scenarios – IP Addressing Xcelerator IP 07008

This Application Note covers two scenarios for applying IP addresses to Xcelerator IP and IP2007 phones on the internal LAN side of Xcelerator IP. The first scenario we are going to look at is a site that already has a cable modem or DSL modem with a built-in router. For this type of installation the best solution would be to have a cable or DSL modem minus the router portion. You would install the Xcelerator IP off the cable/DSL modem and let Xcelerator IP handle the voice and data routing. If that is not an option, what needs to be done is to make sure that the LAN side of the Cable/DSL modem with the built in router is not using the same subnet as the LAN side of Xcelerator IP. If they are both in the same LAN subnet no routing will take place. The second scenario we will discuss is when installing the device within an existing network with a file server/DHCP server that the end user wants use to assign IP addresses for their computers. In this case we will need to mesh the Xcelerator IP into the existing data network environment. There are two ways this can be accomplished. The first method would be to make the LAN side of the Xcelerator IP a static IP address that the IT dept. has taken out of its DHCP pool. You will need one IP address for the Xcelerator IP LAN address, and one IP address for each of the IP2007 phones. The second method would be to let the file server/DHCP server hand out the IP addresses to the phones and the IT dept. pull one IP address out of the DHCP pool that can be assigned statically on the LAN side of the Xcelerator IP. Then, all that is required is to log into the phone, and under the SIP configuration page, set the SIP Proxy Server to be the LAN address of the Xcelerator IP, and setup the subscriber information. Lets discuss the second method first. It will be less time consuming, considering that in the first method you have to statically assign an IP address to each of the phones, whereas in the second method you let the phones get their IP address from existing DHCP server. For this example, the IT Dept. set aside an IP address of 192.168.10.200 with a subnet mask of 255.255.255.0 (/24) to be used as the statically assigned LAN IP address of the Xcelerator IP. After obtaining the address, setup the Static LAN IP address on the Xcelerator IP. To do this, log into the Xcelerator IP and on the left side of the screen click on Advanced then click on LAN. You will see the screen below.

The default LAN IP address is 192.168.1.1 with a subnet mask of 255.255.255.0 (/24). Change the default IP address to the one given to you by the IT Dept (192.168.10.200 /24) to configure the LAN address as shown in the next screenshot.

The LAN IP address has now been changed to 192.168.10.200 . The subnet mask remains the same as default and the option to disable the DHCP server has been chosen. Scroll down to the bottom of the page and click on Save. You will get a pop up message telling you that you should reboot the system before settings are valid.

Click OK, then scroll down the page again and click Reboot. You will see the following screen

This screen advises you to “Close the Xcelerator IP configuration window and wait 2 min. before reopening you web browser. If necessary, reconfigure your PC’s IP address to match you new configuration”. And since we changed the LAN IP address we will need to release and renew our IP address on the PC that is being used to configure the Xcelerator IP. Now that we have a static IP address assigned to the LAN side of the Xcelerator IP and released and renewed our IP address of the machine, we will need to log into the Xcelerator IP and on the left side of the screen we need to click on Voice then Phone and then click on Phone Extension. You will see the following screen:

This page allows you to configure the Authentication for SIP Clients (stations). Here we can enter the extension numbers and the password used for Authentication. To simplify the process, we are going to use the same password for all extensions connected to the system. Assuming we have extensions 100-110, and starting at No. 1, enter the first extension number and its password. Continue to input the data for all extensions up to 110. See the following screen shot for clarification.

When all extensions and passwords have been entered scroll to the bottom of the page and click “Save Settings”

We can now start configuration of the IP2007 phones. Plug the IP2007 phones into the local area network and let them pull an IP address from the local networks File/DHCP server. If the phones pull an IP address from the DHCP server the phones should come up looking like they are working, but they will have the wrong time and date and they all say they are ext. 1001. This is normal. At one of the phones press the softkey labeled Config in the screen. Using the arrow keys or the volume up/down key to navigate, scroll down to “ 5. Info”. Press the checkmark key and scroll down to the IP address of the phone and write it down. Do this for all the IP2007 phones and assign an extension number to each of the IP addresses so that when you go to configure the phone you will know which extension will be assigned to the phone that you logged into. This concludes the process for manually configuring a static IP address scheme for the IP2007 phones.. The next section will cover configuring the IP2007 phones that have pulled an IP address from the File/DHCP server on the local network. From a browser on a PC connected to the local network we can configure the phones to work with the Xcelerator IP. Assume that the 10 IP 2007 phones that we put on the network pulled IP addresses that started with 192.169.10.26 thru 192.168.10.36. From your browser put the IP address of the first phone you wish to configure in the address bar of your. Lets start with the phone with the IP address of 192.168.10.26. We will be making this address station 100. When you get to the login screen enter the username: admin, and the password: 1234. You will get to this screen. (This is not the actual screen shot, the IP address for the phone is not correct. It is for demonstration purposes only).

Across the top of the screen towards the left you will see a tab called SIP, click on it and you will get to the next screen.

Here is where we tell the phone where the SIP Server is (Xcelerator IP).

Here you can see what was changed.

• SIP Proxy Server was changed to 192.168.10.200. • Registrar Server has been changed to 192.168.10.200 • Under Subscriber information, the Phone Number was changed to 100 • Authorized ID was changed to 100 • Authorized Password was changed to 1234.

After all changes have been made scroll to the bottom of the page and click on the Save Setting button. You do not need to reboot the phone after making these changes. The IP2007 phone will go out and find the Xcelerator IP and put the phone into service. At this point look at the Phone, there is a small icon of a phone on the right side of the screen, if the phone has an x in the corner of it, the IP2007 did not register correctly and you should verify all settings. If the phone icon is solid with no x in the corner the IP2007 phone registered properly and is communicating with the Xcelerator IP. Complete this process for the remainder of the phone connected to the system. This completes the process for configuring IP2007 phones using DHCP server for assigning the IP address to the IP2007 phone. If you have any questions, please contact Vertical Customer Support.
