Verify the Network Setup

complete several initial configuration tasks to prepare the network for IP telephony service.
For the phone to operate successfully as an endpoint in your network, your network must meet specific

The phone displays the date and time from Third-Party Call Control. The time displayed on the phone can
differ from the Third-Party Call Control time by up to 10 seconds.
