Configuring the Cisco ATA for SCCP
This section describes how to configure the Cisco ATA to operate with the Skinny Client Control
Protocol (SCCP) signaling image and how the Cisco ATA obtains the latest signaling image.
You can configure the Cisco ATA for use with SCCP with any of the following methods:
• By using the Cisco CallManager TFTP server—This is the Cisco-recommended method for
deploying a large number of Cisco ATAs. This method allows you to set up a default configuration file
for all Cisco ATAs in the network. Additionally, you can set up a configuration file that is unique to a
specific Cisco ATA. When the Cisco ATA powers up or boots up from a reset, it automatically downloads
its configuration file from the Cisco CallManager TFTP server and updates its configuration parameters.
• By using manual configuration:
–
Voice configuration menu—This is the method you must use if the process of establishing IP
connectivity for the Cisco ATA requires changing the default network configuration settings. These
settings are CDP, VLAN, and DHCP. You also can use the voice configuration menu to review all IP
connectivity settings. The voice configuration menu can also be used when Web access is not
available.
–
Web-based configuration—This method is convenient if you plan to deploy a small number of
Cisco ATAs in your network. To use this method, the Cisco ATA must first obtain IP connectivity,
either through the use of a DHCP server or by using the voice configuration menu to statically
configure IP addresses.
This section contains the following topics:
• Default Boot Load Behavior, page 3-2—This section describes the process that the Cisco ATA
follows by default when it boots up. It is very important to understand this process because, if your
network environment is not set up to follow this default behavior, you need to make the applicable
configuration changes. For example, by default, the Cisco ATA attempts to contact a DHCP server
for the necessary IP addresses to achieve network connectivity. However, if your network does not
use a DHCP server, you must manually configure various IP settings as described in this section.
• Specifying a Preconfigured VLAN ID or Disabling VLAN IP Encapsulation, page 3-3—This section
includes a table of the parameters you can configure for VLAN and CDP settings.
• Steps Needed to Configure the Cisco ATA, page 3-6—This section provides tables that summarize
the general configuration steps you must follow to configure the Cisco ATA.
• Configuring the Cisco ATA Using a TFTP Server, page 3-7—This section describes procedures for
configuring the Cisco ATA by using a Cisco CallManager TFTP server, which is the recommended
configuration method for the deployment of a large number of Cisco ATAs.
• Voice Configuration Menu, page 3-18—This section includes information on how to obtain basic
network connectivity for the Cisco ATA and how to perform a factory reset if necessary.
