Re: [Anveo] 'CONTACT CHECK' + 'PRESS KEY' = PERFECT SPAM TRAP said by JoeSchmoe007:I modified my Anveo call flow to use "CONTACT CHECK" + "PRESS KEY" to weed out automated spam calls. I even disabled Black List.
It works great (but "Do Not Answer The Line" has to be UNCHECKED in your Start Control)....
Here is what I currently have happening as a Call Flow :
'Do Not Answer The Line' is also UNCHECKED in MY 'Start' Control. - Thanks for the tip, Joe, the first time you posted about that. 
My outgoing message simply tells EVERYONE that in order to show that they are not a Robo Caller, to please to press 3 to continue.
Pressing 5 goes directly to Voicemail, but some folks said that telling them this was confusing (too much info, as well as raising a further question in their minds as to whether or not ringing the phone will/won't ALSO lead to VM), so I do not mention VM at all anymore.
In my SIP control/step, I have set it to go to VM after 45 seconds (about 7 rings), though I do not explain that either, as it is a common setting.
Strangely enough, my web portal call log shows very few calls which deserve to be on a blacklist since porting the number to Anveo and conjuring up this call flow, but I view it a 'Calm Before the Next Storm'.  
I have not developed my Black or White lists yet, but as you can see, the steps are in place to admin them when I do.
The only question left in MY mind is whether to use a blacklist, a whitelist, or both, but for now I'm just seeing how effective the 'Press Key' step seems to be on its own. |

Farmington, MI | I think you'll find a white list, where calls from "business", "family" and "friend"(s) can bypass the press key test and go directly to the sip forward, will be helpful. Only "other" callers would need to be checked with the key press. |

Possibly, but whether or not I do anything else at all will depend mostly upon :
(1) how much unwanted traffic gets past the 'Press Key' control, and
(2) how well that Anveo's CNAM dipping works for what little it costs me.
Besides, what's a single key stroke among friends ? |

I strongly recommend that you implement the whitelist ASAP, at least for your parents / wife / kids / anyone that you really care about.
It's dangerous to send DTMF while driving. In the good old days, it wasn't so bad -- you would just feel for the 3 button. But with Android or iPhone, you have to take your eyes off the road twice, first to find the "show keypad" button, then to find the 3.
If you insist on IVR for all, your contacts may be able to automate pressing 3. If their hands-free calling is phone-based, it is a simple matter of programming the Contact entry to have a "pause" followed by 3. However, if they are using the "dial by name" function of their car's multimedia system, then the pause function needs to be set in the car's phonebook, and some don't have that feature.
Other disadvantages of the forced IVR include that a caller will be charged one minute, even if they hang up before you answer. Also, it thwarts automation on the caller's side, e.g. if they want a speed dial on their PBX that will call your mobile, if you don't answer at home. |

I completely agree with suggestions regarding whitelist.
As far as caller being charged for 1 minute even if they hang up - either CONTACT CHECK or some other controls in my workflow will not work unless "Do Not Answer The Line" is UNCHECKED in your Start Control. As soon as you do this callers will always be charged for one minute even if they hang up at any point because your line is answered immediately. |

Any comment on what the 'other' and 'spam' outputs of "Contact Check" contain? Is my try above close to correct? |

Interesting reasoning.
I get it.
But the rest can go to Hell, then ?
Come to think of it, that's usually where I would LIKE to send telemarketers, survey takers, and bill collectors.  |

Yes, I noticed that behaviour while I was testing my various lines for CNAM performance by calling them from each other.
So it's a trade-off, one function for another - no free lunches, etc.... |

Stewart is suggesting that you pass the call from friends etc right through with no further test, but to give those not on the nice list a chance at pressing the key to get through your test. My diagram above intends to implement that. I added that diagram after your post as an edit. |

Yes, I see that you did - looks like it would work.
And yes, I was being facetious.  |
