Auto-Configuration on the Cisco VG202 and Cisco VG204 Voice Gateways Chapter 4 Configuring Voice Auto-Configuration With a DHCP Server When the DHCP server is available, the voice gateway sends a DHCP server request to provide the IP address for the Fast Ethernet 0/0 interface, and the TFTP server's IP address using the DHCP option 150. When the DHCP server provides the information, the voice gateway provisions itself with the CCM configuration using Skinny Call Control Protocol (SCCP). Analog ports which have been pre-configured on CCM automatically register on CCM as SCCP controlled ports. To provision the voice gateway with auto-configuration when a DHCP server is available, use the following commands.

Enters global configuration mode. You have entered global configuration mode when the prompt changes to VG(config)#. Enters interface configuration mode and specifies the type of interface you plan to configure. You have entered interface configuration mode when the prompt changes to VG(config-if)#. Acquires an IP address on an interface from the Dynamic Host Configuration Protocol (DHCP). Cisco VG202 and Cisco VG204 Voice Gateways Software Configuration Guide 4-4 OL-16191-01
