My Project is to control the household equipment/s through land line phone. It consists of following (circuit attached). I wired the circuit connected the incoming landline wire and 5V DC supply and called the no. The green LED is blinking as the phone is ringing but circuit does not respond ie it should behave as if phone at remote end is lifted with melody coming from UM66.
I am getting supply at output of 3140e.
Instead of CM8870 i have used MT8870DE.
