Chapter3 Configuring the Cisco ATA for SIP
Configuring the Cisco ATA Using a TFTP Server
For an example of how to configure parameters for the TFTP Server con figuration method, see the
“Creating Unique and Common Cisco ATA Configuration Files” section on page3 -8.
Note Be sure to configure the UseSIP parameter to the value of 1 to enable the SIP protocol. This parameter
is 0 (for H.323) by default.
Creating Unique and Common Cisco ATA Configuration Files
If you have many Cisco ATAs to configure, a good approach is to create two configuration files:
•One file that will contain only parameter values unique to a specific CiscoATA.
•One file for parameters that will be configured with values common to a group of Cisco ATAs. If
this file is updated, all CiscoATA devices in this common group can obtain the new configuration
data in a batch-mode environment.
The following procedure demonstrates the steps needed to create these configuration files.
Note The parameters used in this section help illustrate the process of creating a unique CiscoATA
configuration file, and do not include all required SIP parameters in the examples. See Chapter 4, “Basic
and Additional SIP Services,” for complete listings and descriptions of required parameters and
additional configurable features. Also, refer back to Table 3-3 on page 3-5 for all main configuration
steps.
Procedure
Step 1 Use the example_uprofile.txt file as a template for creating a text file of values that are common to one
group of Cisco ATAs. The example_uprofile.txt file is included in the software-release zip file and
contains all default values. This file is shown without its annotations in the “Configuration Text File
Template” section on page5-2.
Copy the example_uprofile.txt file and save it with a meaningful name, such as common.txt.
Step 2 Configure all common parameters by editing the text file as desired. For example, you might configure
some parameters as follows:
ToConfig:0
UseTftp:1
DHCP:1
TFtpURL:10.10.10.1
UseSIP:1
Tip It is helpful to always include the parameter/value of ToConfig:0 in the CiscoATA
configuration file so that every time this file is downloaded to the CiscoATA, it will set
ToConfig to 0, which the appropriate value for this parameter once the Cisco ATA has been
configured. If ToConfig is 1, the CiscoATA will continue to unnecessarily contact the TFTP
server.
