IMPORTANT: For testing, the trunk must be connected to a Cisco UC320W FXO

port. After the test, if you wish to connect the trunk to a Cisco SPA8800 instead,

you can input the recommended settings in the fields for the Cisco SPA8800. Take

care to ensure that you physically connect the trunk to the corresponding

SPA8800 port.

STEP 1 Connect an FXO trunk to an available port on the Cisco UC320W.

STEP 2 In the Phone number for testing box, enter an external phone number that you

can call and answer during the test. Enter the complete phone number, without

spaces or punctuation. No steering digit is required for an FXO call.

STEP 3 Choose the port where you connected the trunk. Refer to the port labels on the

device to ensure that you choose the correct port.

test will take about 5 minutes. When the status icon and recommended settings

appear, hang up your phone. Note: For more information about the status icons,

STEP 6 In the lower half of the screen, find the port where you want to use this trunk, and

enter the recommended settings. If you choose a port other than the tested port,

physically connect the trunk to the port now. Refer to the port labels on the device

to ensure that you connect the trunk to the correct port.

STEP 7 If needed, repeat the above steps for other trunks.

STEP 8 When finished with all tests, click the Apply button to immediately apply the new
