[Resolved]  BSNL, UDUPI, Kemmannu exchange — Phone not working

Our BSNL landline phone no[protected] is not working when there is no power in our area ,regading this I have complented to all the authorities ,and every person is saying that the phone works in DC but not in AC , Although I convinced them regarding this problem and said them to visit our home when there is power failure, Some people visited our home when there was no power and they observed the problem and still they are not able to rectify the problem ,We are facing this problem since last 6 monts and daily I am giving complent to exchage regarding this.
