VPM220W to the videoconferencing endpoint, you must enable the Wi-Fi hotspot and the
Dynamic Host Configuration Protocol (DHCP) service on the videoconferencing endpoint to
obtain the IP address of the VPM220W. The videoconferencing endpoint functions as the
DHCP server, and the VPM220W serves as the DHCP client. For details about how to enable
the DHCP service, see the user guide for the HUAWEI TEX0 videoconferencing endpoint.
