Verify the Network Setup

Upon deployment of a new IP telephony system, system administrators and network administrators must
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
requirements.
Note 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.
Procedure
Step 1 Configure a VoIP Network to meet the following requirements:
• VoIP is configured on your Cisco routers and gateways.
• Third-Party Call Control is installed in your network and is configured to handle call processing.
