What does volte HD call mean?

VOLTE is called Long Term Evolution Voice, which means the high-speed wireless communication standard for mobile phones and data terminals.

Based on the IP Multimedia Subsystem (IMS) network, it uses special configuration files for the control layer and media layer of voice services in LTE, so that voice services can be transmitted as data streams in the LTE data bearing network without maintaining and relying on the traditional circuit-switched voice network.
