NTP server or a DATE header supplied by the ITSP. Following is an example of a 200 response to
REGISTER (note that there is no weekday in the DATE header):

Troubleshooting and Configuration FAQ
This section provides solutions to problems that may occur during the installation and
operation of the SPA9000. If you can't find an answer here, check the Linksys website at
www.linksys.com.
1. The SPA9000 did not automatically assign an extension number to the Linksys IP Phone, and the
phone Ext LED is yellow instead of green.
There are two solutions to the common causes of this problem.
First solution:
A. Connect an analog phone to the SPA9000 and access the IVR by pressing ****.
B. Press 180# to hear the multicast address and port assigned to the SPA9000.
C. If the problem is with a SPA901, perform these steps to verify and correct the multicast address:
• Use option 180# on the IVR to determine the multicast address of the phone that is not getting
configured.
• If the addresses or ports are different, press 181# to set the address and port of the phone to
match the SPA9000. Use a * to separate each set of digits in the IP address and before the port
number.
D. If the problem is with any SPA900 Series phone with an LCD display, perform these steps to
verify and correct the multicast address:
• Press the Menu button (to the right of the 6) and scroll down to Network and press Select.
• Scroll to the bottom of the Network list (you can get there quickly by pressing the up arrow)
and view the Multicast Address.
• If the address and port does not match the SPA9000, press Edit, and enter the correct address
and port. Then press OK.
E. Restart the SPA900 Series phone.
Second solution:
A. Open the web browser on the administration computer.
B. Enter http://ipaddress/admin/router/status.
C. Write down the Current IP of the SPA9000. (This is the Internet IP address.)
D. Access the phone administration web server at the following URL:
http://phone_ip_address/
To determine the IP address of the phone, press the Menu button and select Network from the
LCD menu. For a SPA901 phone, use IVR option 110#.
