Chapter 4 Configuring Voice
Auto-Configuration on the Cisco VG202 and Cisco VG204 Voice Gateways
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.
