IP phones are usually configured and registered via a web interface. For example, for XUNMEISD’s XM1810 IP phone, you can open the IE browser on a PC terminal in the local area network, enter the IP address of the IP phone, and access the web interface for configuration and registration. Then enter the registration address, registered extension and registration password provided by the IP phone server provider on the line page. The specific steps may vary with different brands and models of IP phones. It is recommended to refer to the official documentation of the corresponding brand of IP phone or contact customer service for detailed registration guidance.
