Resolving Startup Problems

Symptom: The ATA 190 Does Not Register with Cisco Unified Communications
Manager
If the phone proceeds past the first stage of the startup process, with the LED buttons flashing on and
off, but continues to cycle through the messages, the phone is not starting up properly. The phone cannot
successfully start up unless it is connected to the Ethernet network and it has registered with a
Cisco Unified Communications Manager server.
These sections can assist you in determining the reason the phone is unable to start up properly:

Checking Network Connectivity
If the network is down between the phone and the TFTP server or Cisco Unified Communications
Manager, the phone cannot start up properly. Ensure that the network is currently running.
Verifying TFTP Server Settings
You can determine the IP address of the TFTP server used by the ATA 190 by entering http://x.x.x.x
where x.x.x.x is the IP address of the ATA 190.
If you have assigned a static IP address to the phone, manually enter a setting for the TFTP Server 1
option. See the
If you are using DHCP, the phone obtains the address for the TFTP server from the DHCP server. Check
the IP address that is configured in Option 150 or Option 66.
You can also enable the phone to use an alternate TFTP server. Such a setting is very useful if the phone
was recently moved from one location to another. See the
Phone Setting" section on page B-1
Verifying DNS Settings
If you are using DNS to refer to the TFTP server or to Cisco Unified Communications Manager, ensure
that you have specified a DNS server. Verify this setting by entering http://x.x.x.x where x.x.x.x is the IP
address of the ATA 190. Also, verify that there is an A entry in the DNS server for the TFTP server and
for the Cisco Unified Communications Manager system.
Also, ensure that DNS is configured to do reverse look-ups.
