What should I do if the registration status of our Hua Qin Telecom HGU42 1N v3 E8-C-EPON broadband voice message prompt is disabled?

Voice is the function of solidifying the line connected from the light cat. Since it is disabled, it means that the voice function of the optical cat equipment is prohibited in the main computer room of the telecommunications bureau. Then you can call the customer service hotline for manual or broadband repair. If no one can get through, you can only go to the business hall and ask someone to help you set up the voice function to register and activate the light cat.
