Upon repeated request since last one month that the outgoing call from TATA Indicom residential line to the Airtel mobile (Rajasthan Connection) is not functioning. From the land line when the call connect to the mobile the person on the land line can not hear the voice of other end. The authorities are hesitating to change the instrument and the funny thing is that when you switch of the land phone for minutes and tray again it will be connected properly.
