Answer 1

To resolve a duplicate IP address on a VoIP phone, the first step is to reboot the phone to allow it to request a new IP from the DHCP server. If that doesn't work, further troubleshooting is needed.

Step-by-step explanation:

If a client reports that their VoIP phone screen displays a duplicate IP address, the first action you should try to resolve this problem is D. Reboot the phone. This is a common first step in troubleshooting network equipment as it allows the device to reinitialize its network configuration and request a new IP address from the DHCP server. If rebooting the phone does not resolve the issue, further troubleshooting steps such as checking LAN connections or consulting with the vendor may be required.
