perform a local loopback test to check the network connection at your site or a remote
loopback test to check the network connection at a remote site. While a remote loopback test
is being performed, data is transmitted from your site to a remote site and then back to your
site.
To enable your endpoint to communicate with other endpoints, stop the loopback test.
You cannot perform a loopback test on remote video during a dual-stream conference.

Before a network test, ensure that your endpoint is connected to an IP network and IP
parameters are set correctly.
If your endpoint is on a public network: In
IP address
, enter an IP address that is in a
different network segment from your endpoint IP address. Then select
Start
. If the test is
successful, the gateway settings and IP address of your endpoint are correct.
If your endpoint is on a private network: In
IP address
, enter a public IP address. Then
select
