Disconnected Number app?

---

I apologize if this already exists, but I was unable to find anything on Google or the forums here.

I'm wondering if it's feasible to create an apk that will do the following:

Upon incoming call, check the number. If it exists in a database of user-added numbers, or is Unknown/Private (if this setting is selected), then the call is answered by the phone automatically (without playing a ringtone), the mic is shut off, and it plays back a recording of the "The number you have dialed is not in service". Set it to disconnect after 30 seconds or so, if the other end of the call doesn't end it themselves.

I believe this would be useful as a sort of black-listing program, and should anyone call that number while blacklisted, they would most likely remove the number from their list. I see this being beneficial for telemarketers, collections calls, Ex-boyfriends/ex-girlfriends, that stranger in the bar you gave your number out to after you had too much to drink, etc.

While I realize there are a number of call-blocking programs out there, I think the main selling point of this would be that it would stop the calls from coming from that source.

Sorry if a thread like this exists somewhere, or even an app, but I couldn't find anything. I've just been thinking about this a lot lately, and while I have some experience programming, I have yet to touch anything for the Android OS.

Thanks!

check the market for a callblock app, shold be what your looking for

Not exactly. The call blocking applications I've seen so far either send them directly to voicemail, or pick up the call and immediately hang up on them.

The primary difference I'm looking for is muting the microphone and playing back a message prior to hanging up the call.


Does this already exist? If not, is it possible to create? Again, I have no experience coding for Android, so I don't know what we can and cannot do, although I imagine it probably would be possible, preferably without root (so as to reach a wider audience).

i believe you can do this with google voice.

i think if you mark the number as spam or block it in google voice it plays that type of message.

The only problem with that, is it requires the use of the Google Voice number, right? Which does not help for those who already have the current number. See OP:

I apologize for this needing to be moved. My original question was actually whether or not it was possible, but this turned more into a "Try this app" thread.

i believe if you end up using google voice for voice mail (where you dont have to have a gv number) it does this also.
