Check Tftp Settings; Start Service; Determine Dns Or Connectivity Issues - Cisco 8831 Administration Manual

Troubleshooting procedures

Check TFTP settings

Procedure
Step 1
You can determine the IP address of the TFTP server used by the conference phone by choosing Apps >
Admin Settings > Network Setup > IPv4 Configuration > TFTP Server 1 .
Step 2 If you have assigned a static IP address to the conference phone, you must manually enter a setting for the
TFTP Server 1 option.
Step 3 If you are using Dynamic Host Configuration Protocol (DHCP), the conference phone obtains the address for
the Trivial File Transfer Protocol (TFTP) server from the DHCP server. A valid TFTP server must be set in
DHCP option 150 or option 66 on the DHCP server.
Step 4 You can also enable the conference phone to use an alternate TFTP server. Such a setting is particularly useful
if the conference phone was recently moved from one location to another.
