Is the hotel landline still available when it is disconnected?

I can't. The landline needs the current and voltage transmitted on the telephone line to work properly. If the telephone line is broken, the landline can't get the power and signal it needs, and the hotel landline can't be used if it is broken. Fixed telephone, commonly known as landline, refers to the telephone fixed in a certain position, which is different from mobile phone (mobile phone) and is mostly used in enterprises.
