Setting the Codec
The LBRCodec (low-bit-rate codec) parameter determines whether the G.723 or G.729A codec, in
addition to G.711A-law and G.711µ-law, can be used for receiving and transmitting. For configuration
information, see the “LBRCodec” section on page 5-20.
Configuring Refresh Interval
When the value specified in the CfgInterval parameter is reached, the Cisco ATA attempts to refresh its
configuration file from the TFTP server. By opening a web page for the Cisco ATA, you can perform a
refresh before the scheduled refresh. Set the CfgInterval parameter to an interval value (in seconds) for
refreshing the Cisco ATA configuration file. Cisco recommends that the interval be semi-random to
prevent many simultaneous contacts with the TFTP server. For more information, see the “CfgInterval”
section on page 5-5.
When the Cisco ATA contacts the TFTP server, it also checks to see if an upgrade signaling image has
been placed on the TFTP server. If such an image exists, the Cisco ATA will download this image.
