A busy tone indicates that the party you called is not available. Try your call again later. A fast-busy
tone indicates that you dialed an invalid number.
After power up, if the function button continues to blink slowly, the Cisco ATA cannot locate the
DHCP server. Check the Ethernet connection and the availability of the DHCP server.
The DHCP server should show an incoming request from the MAC address listed on the product
label or given by the voice prompt.
If you place a call to another IP telephone, detect ringing, and the called party answers but you
cannot detect the speaker's voice, verify that the Cisco ATA and the other IP telephone support at
least one common audio codec: G.711A-law, G.711µ-law, G.723.1, or G.729A.
Parameters with values set by using the web server interface or voice configuration menu
Possible Cause You are using TFTP for configuration (the UseTFTP parameter is set to 1). The
Cisco ATA has a cached version of its configuration file stored in its flash memory; this is what
displayed or played through the web server interface or voice configuration menu. If UseTFTP is
set to 1, then the cached value of the Cisco ATA configuration file is synchronized with its
configuration file located at the TFTP server. This synchronization update of the cached value
occurs at approximate intervals determined by the CFGInterval parameter value as well as when the
Cisco ATA powers up or resets.
If you are using TFTP for configuration, do not use the web server interface or
Recommended Action
voice configuration menu to modify the value of the Cisco ATA configuration file. Use the web
server interface or voice configuration menu only to initially configure the Cisco ATA to contact
the TFTP server for the Cisco ATA configuration file.
Unable to access the web configuration page.
Possible Cause Software versions earlier than 2.0 require the web configuration page to be enabled
using option 80# on the voice configuration menu.
Upgrade the software.
Recommended Action
The Cisco ATA does not seem to be configured using the TFTP server.
The TFTP server address is not properly set.
Possible Cause
Recommended Action Ensure that the TftpURL is correctly set to the URL or IP address of the TFTP
server that is hosting the configuration file for the Cisco ATA. If you are using DHCP to supply the
TFTP server IP address, make sure that the TftpURL is set to 0. Also, unless the TftpURL is an IP
address, be sure that the DNS1IP and DNS2IP values are properly set to resolve the TftpURL
supplied by DHCP.
