Cisco phones use the proprietary option 150 to tell the phone what server to contact for configuration information. How can I provide this option using the ISC DHCP. ![]() This document describes how to configure a Dynamic Host Configuration Protocol (DHCP) Server on Windows 2000 to work with the Cisco IP Telephony solution, Cisco CallManager. Cisco CallManager devices boot up and request an IP address. They also need additional information, such as the default gateway and the TFTP Server IP Address (Option 150). This document provides a step-by-step procedure on how to configure all the necessary parameters for the Windows 2000 DHCP Server. There are no specific prerequisites for this document. This document is not restricted to specific software and hardware versions. For more information on document conventions, refer to the. Cd tim maia o melhor de tim maia 2009 movies about cheating. The configuration of the Windows 2000 DHCP Server for Cisco CallManager has two major tasks. Complete these steps in order to create a new DHCP scope. • Select Start > Programs > Administrative Tools > DHCP in order to go to the DHCP Manager. • Right-click the DHCP Server and click New Scope. • Follow the instructions in the New Scope Wizard. • Add a Name and a Description for your new scope and click Next in order to continue. • Add the IP Address Range which you want the DHCP Server to hand out IP Addresses in. Make sure to set the subnet mask correctly for what your network settings are. Click Next to continue. Note: You may want to exclude IP Addresses within this range that have been previously assigned to other devices, so that the same addresses are not used twice. • Set the Lease Duration to a value that makes sense for your network. This is how often the IP address of a device expires and it needs to be renewed by the device. Click Next to continue. • You need to configure additional options for the devices to pick up when they get their IP Addresses from the DHCP Server. Select Yes, I want to configure these options now option. Click Next to continue. • All devices need a Default Gateway configured. This is the router interface nearest to the devices, which has an interface on the same IP subnet as the devices. This is where the devices send IP packets if the receiving device is not on the same IP subnet as the sending device. Tajima dgml by pulse edition x2 maestro hulk artist.

Type the IP address of the Default Gateway and click Add. Note: If you intend to use the Domain Name System (DNS) in your network, you can configure the device to receive an IP address for the domain name and DNS servers. • Skip the Windows Internet Naming Service (WINS) server configuration because Cisco CallManager devices do not use WINS (just click Next). Then Click No, I will activate this scope later. • Click Finish. The new DHCP Scope is now created. However, it is not Active and does not hand out IP addresses yet. Cisco IP Phones expect the DHCP server to also provide the IP address of the TFTP server. By default, the TFTP option is not available in a newly defined DHCP scope. Complete these steps in order to add the TFTP option to the scope. • Right-click the server and select Set Predefined Options, then click Add. ![]() • Enter the Name as TFTP Server IP Address, Data Type is IP Address, Code is 150, and Description is TFTP Server IP Address for CallManager Devices. • Click OK and then Edit Array. Enter the IP address(es) for TFTP server(s) that are normally housed on the Cisco CallManager systems. • Click OK twice in order to complete the creation of Option 150. Under the new Cisco CallManager DHCP Scope you created is a field labeled 'Scope Options'. If you right-click Scope Options and select Configure Options, you can select Option 150 as an option to hand out to Devices. • Click Apply and OK in order to see that the scope now has Option 150. • Right-click the Scope and select Activate in order to activate the Scope.
