Setting the Codec

The LBRCodec (low-bit-rate codec) parameter determines w hether 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 CiscoATA 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 paramet er to an interval value (in seconds) for
refreshing the CiscoATA 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 CiscoATA 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 CiscoATA will download this image.
