Specifying a Preconfigured VLAN ID or Disabling VLAN IP
Encapsulation
If you want the Cisco ATA to use a preconfigured VLAN ID instead of using the Cisco Discovery
Protocol to locate a VLAN, or if you want to disable VLAN IP encapsulation, refer to
reference to the parameters and bits you may need to configure. Use the voice configuration menu to
configure these parameters. (See the
on using this menu.) Also, refer to
and bits to configure depending on your network environment.

The Cisco ATA contacts the TFTP server and downloads the Cisco ATA release software that
contains the correct signaling image for the Cisco ATA to function properly.
If you are not using a TFTP server, you need to manually upgrade the Cisco ATA to the correct
signaling image. For information on this procedure, see the
Manually" section on page
The Cisco ATA looks for a Cisco ATA-specific configuration file (designated by the MAC address
of the Cisco ATA and named ata<macaddress>) on the TFTP server and downloads this file if it
exists.
If the Cisco ATA does not find the ata<macaddress> configuration file, it looks for the
atadefault.cfg configuration file and downloads this file if it exists. This file can contain default
values for the Cisco ATA to use.
Parameters and Bits for Preconfiguring a VLAN ID
Bit 4—Enable the use of user-specified voice VLAN ID.
Bit 5—Disable VLAN encapsulation
Bit 6—Disable CDP discovery.
Bits 0-2—Specify VLAN CoS bit value (802.1P priority) for TCP
packets.
Bits 3-5—Specify VLAN CoS bit value (802.1P priority) for UDP
packets
Bits 18-29—User-specified 802.1Q VLAN ID
