With the Telcom Drop powered up and connected to my Internet VOIP / Router installation Message recorded and timer adjusted I am ready for any unwanted call.
When a call comes in and I see it on my Television and its and unwanted call I push the play button and the Telcom Drop does its thing. It tells the modem to answer the call and play the message then turn off the modem.
Ultimate Unexpected Result:
PRIVACY When you want it. 99% of the Recording being done (Eavesdropping) is done by the phone lines via speaker phones. So another option is to activate the modem & play the recording and press the LOCK BUTTON on the case that will keep the message going until you are done with your private conversation. Press the UNLOCK BUTTON and the unit releases the MODEM and is ready for use on the next unwanted call.
The final boards will be ready in about 2-3 weeks so I can make one for my family and all that want it as well.
