General Troubleshooting Tips
The suggestions in this section are general troubleshooting tips.
•Make sure that the DHCP server is operating correctly. Note that the function button blinks slowly when the Cisco ATA attempts to acquire the DHCP configuration.
•If the green activity LED is not flashing after you connect the Ethernet cable, make sure that both the power cord and the Ethernet connection are secure.
•If there is no dial tone, make sure that the telephone line cord from the telephone is plugged into the appropriate port on the Cisco ATA. Make sure that your Cisco ATA is properly registered on your Call Control system. Test another phone; if this phone does not work either, there may be a problem with the current configuration or with the Cisco ATA.
•A busy tone indicates that the party you called is not available. Try your call again later. A
•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:
