(see: -https://www.donotcall.gov/default.aspx ) But, this list won't protect -from the Charities, previous business relationships, etc. - - -================================= -Next, Fight against autodialers!! -================================= - -Zapateller detects if callerid is present, and if not, plays the -da-da-da tones that immediately precede messages like, "I'm sorry, -the number you have called is no longer in service." - -Most humans, even those with unlisted/callerid-blocked numbers, will -not immediately slam the handset down on the hook the moment they hear -the three tones. But autodialers seem pretty quick to do this. - -I just counted 40 hangups in Zapateller over the last year in my -CDR's. So, that is possibly 40 different telemarketers/charities that have -hopefully slashed my back-waters, out-of-the-way, humble home phone -number from their lists. - -I highly advise Zapateller for those seeking the nirvana of "privacy". - - -======================================= -Next, Fight against the empty CALLERID! -======================================= - -A considerable percentage of the calls you don't want, come from -sites that do not provide CallerID. - -Null callerid's are a fact of life, and could be a friend with an -unlisted number, or some charity looking for a handout. The -PrivacyManager application can help here. It will ask the caller to -enter a 10-digit phone number. They get 3 tries(configurable), and this is -configurable, with control being passed to priority+101 if they won't -supply one. - -PrivacyManager can't guarantee that the number they supply is any -good, tho, as there is no way to find out, short of hanging up and -calling them back. But some answers are obviously wrong. For instance, -it seems a common practice for telemarketers to use your own number -instead of giving you theirs. A simple test can detect this. More -advanced tests would be to look for -555- numbers, numbers that count -up or down, numbers of all the same digit, etc. - -My logs show that 39 have hung up in the PrivacyManager script over -the last year. - -(Note: Demanding all unlisted incoming callers to enter their CID may -not always be appropriate for all users. Another option might be to -use call screening. See below.) - -========================== -Next, use a WELCOME MENU ! -========================== - -Experience has shown that simply presenting incoming callers with -a set of options, no matter how simple, will deter them from calling -you. In the vast majority of situations, a telemarketer will simply -hang up rather than make a choice and press a key. - -This will also immediately foil all autodialers that simply belch a -message in your ear and hang up. - - ----------------------------------------------- -Example usage of Zapateller and PrivacyManager: ----------------------------------------------- - -[homeline] -exten => s,1,Answer -exten => s,2,SetVar,repeatcount=0 -exten => s,3,Zapateller,nocallerid -exten => s,4,PrivacyManager -exten => s,105,Background(tt-allbusy) ;; do this if they don't enter a number to Privacy Manager -exten => s,106,Background(tt-somethingwrong) -exten => s,107,Background(tt-monkeysintro) -exten => s,108,Background(tt-monkeys) -exten => s,109,Background(tt-weasels) -exten => s,110,Hangup -exten => s,5,GotoIf($[ "${CALLERIDNUM}" = "7773334444" & "${CALLERIDNAME}" : "Privacy Manager" ]?callerid-liar|s|1:s|7) - -I suggest using Zapateller at the beginning of the context, before -anything else, on incoming calls.This can be followed by the -PrivacyManager App. - -Make sure, if you do the PrivacyManager app, that you take care of the -error condition! or their non-compliance will be rewarded with access -to the system. In the above, if they can't enter a 10-digit number in -3 tries, they get the humorous "I'm sorry, but all household members -are currently helping other telemarketers...", "something is terribly -wrong", "monkeys have carried them away...", various loud monkey -screechings, "weasels have...", and a hangup. There are plenty of -other paths to my torture scripts, I wanted to have some fun. - -In nearly all cases now, the telemarketers/charity-seekers that -usually get thru to my main intro, hang up. I guess they can see it's -pointless, or the average telemarketer/charity-seeker is instructed -not to enter options when encountering such systems. Don't know. - -=================== -Next: Torture Them! -=================== - -I have developed an elaborate script to torture Telemarketers, and -entertain friends. (See -http://www.voip-info.org/wiki-Asterisk+Telemarketer+Torture ) - -While mostly those that call in and traverse my teletorture scripts -are those we know, and are doing so out of curiosity, there have been -these others from Jan 1st,2004 thru June 1st, 2004: -(the numbers may or may not be correct.) - -603890zzzz hung up telemarket options. -"Integrated Sale" called a couple times. hung up in telemarket options -"UNITED STATES GOV" (-- maybe a military recruiter, trying to lure one of my sons). -800349zzzz -- hung up in charity intro -800349zzzz -- hung up in charity choices, intro, about the only one who actually travelled to the bitter bottom of the scripts! -216377zzzz -- hung up the magazine section -626757zzzz = "LIR " (pronounced "Liar"?) hung up in telemarket intro, then choices -757821zzzz -- hung up in new magazine subscription options. - -That averages out to maybe 1 a month. That puts into question whether -the ratio of the amount of labor it took to make the scripts versus -the benefits of lower call volumes was worth it, but, well, I had fun, -so what the heck. - -but, that's about it. Not a whole lot. But I haven't had to say "NO" -or "GO AWAY" to any of these folks for about a year now ...! - -======================================== - Using Call Screening -======================================= - -Another option is to use call screening in the Dial command. It has -two main privacy modes, one that remembers the CID of the caller, and -how the callee wants the call handled, and the other, which does not -have a "memory". - -Turning on these modes in the dial command results in this sequence of -events, when someone calls you at an extension: - -1. The caller calls the Asterisk system, and at some point, selects an -option or enters an extension number that would dial your extension. - -2. Before ringing your extension, the caller is asked to supply an -introduction. The application asks them: "After the tone, say your -name". They are allowed 4 seconds of introduction. - -3. After that, they are told "Hang on, we will attempt to connect you -to your party. Depending on your dial options, they will hear ringing -indications, or get music on hold. I suggest music on hold. - -4. Your extension is then dialed. When (and if) you pick up, you are -told that a caller presenting themselves as <their recorded intro is -played> is calling, and you have options, like being connected, -sending them to voicemail, torture, etc. - -5. You make your selection, and the call is handled as you chose. - - -There are some variations, and these will be explained in due course. - - -To use these options, set your Dial to something like: - -exten => 3,3,Dial(Zap/5r3&Zap/6r3|35|tmPA(beep)) - -or - -exten => 3,3,Dial(Zap/5r3&Zap/6r3|35|tmP(something)A(beep)) - -or - -exten => 3,3,Dial(Zap/5r3&Zap/6r3|35|tmpA(beep)) - - -The 't' allows the dialed party to transfer the call using '#'. It's -optional. - -The 'm' is for music on hold. I suggest it. Otherwise, the calling -party gets to hear all the ringing, and lack thereof. It is generally -better to use Music On Hold. Lots of folks hang up after the 3rd or -4th ring, and you might lose the call before you can enter an option! - -The 'P' option alone will database everything using the extension as a -default 'tree'. To get multiple extensions sharing the same database, use -P(some-shared-key). Also, if the same person has multiple extensions, -use P(unique-id) on all their dial commands. - -Use little 'p' for screening. Every incoming call will include a -prompt for the callee's choice. - -the A(beep), will generate a 'beep' that the callee will hear if they -choose to talk to the caller. It's kind of a prompt to let the callee -know that he has to say 'hi'. It's not required, but I find it -helpful. - -When there is no CallerID, P and p options will always record an intro -for the incoming caller. This intro will be stored temporarily in the -/var/lib/asterisk/sounds/priv-callerintros dir, under the name -NOCALLERID_<extension><channelname> and will be erased after the -callee decides what to do with the call. - -Of course, NOCALLERID is not stored in the database. All those with no -CALLERID will be considered "Unknown". - -======================== - The 'N' and 'n' options -======================== - -Two other options exist, that act as modifiers to the privacy options -'P' and 'p'. They are 'N' and 'n'. You can enter them as dialing -options, but they only affect things if P or p are also in the -options. - -'N' says, "Only screen the call if no CallerID is present". So, if a -callerID were supplied, it will come straight thru to your extension. - -'n' says, "Don't save any introductions". Folks will be asked to -supply an introduction ("At the tone, say your name") every time they -call. Their introductions will be removed after the callee makes a -choice on how to handle the call. Whether the P option or the p option -is used, the incoming caller will have to supply their intro every -time they call. - -======================= -Recorded Introductions -======================= - -[Philosophical Side Note: -The 'P' option stores the CALLERID in the database, along with the -callee's choice of actions, as a convenience to the CALLEE, whereas -introductions are stored and re-used for the convenience of the CALLER.] - -Unless instructed to not save introductions (see the 'n' option above), -the screening modes will save the recordings of the caller's names in -the directory /var/lib/asterisk/sounds/priv-callerintros, if they have -a CallerID. Just the 10-digit callerid numbers are used as filenames, -with a ".gsm" at the end. - -Having these recordings around can be very useful, however... - -First of all, if a callerid is supplied, and a recorded intro for that -number is already present, the caller is spared the inconvenience of -having to supply their name, which shortens their call a bit. - -Next of all, these intros can be used in voicemail, played over -loudspeakers, and perhaps other nifty things. For instance: - -exten => s,7,System(/usr/bin/play /var/lib/asterisk/sounds/priv-callerintros/${CALLERIDNUM}.gsm&|0) - -When a call comes in at the house, the above priority gets executed, -and the callers intro is played over the phone systems speakers. This -gives us a hint who is calling. - -(Note: the |0 option at the end of the System command above, is a -local mod I made to the System command. It forces a 0 result code to -be returned, whether the play command successfully completed or -not. Therefore, I don't have to ensure that the file exists or -not. While I've turned this mod into the developers, it hasn't been -incorporated yet. You might want to write an AGI or shell script to -handle it a little more intelligently) - -And one other thing. You can easily supply your callers with an option -to listen to, and re-record their introductions. Here's what I did in -the home system's extensions.conf. (assume that a -Goto(home-introduction|s|1) exists somewhere in your main menu as an -option): - -[home-introduction] -exten => s,1,Background,intro-options ;; Script: To hear your Introduction, dial 1. - ;; to record a new introduction, dial 2. - ;; to return to the main menu, dial 3. - ;; to hear what this is all about, dial 4. -exten => 1,1,Playback,priv-callerintros/${CALLERIDNUM} -exten => 1,2,Goto(s,1) -exten => 2,1,Goto(home-introduction-record,s,1) -exten => 3,1,Goto(homeline,s,7) -exten => 4,1,Playback,intro-intro ;; Script: - ;; This may seem a little strange, but it really is a neat - ;; thing, both for you and for us. I've taped a short introduction - ;; for many of the folks who normally call us. Using the Caller ID - ;; from each incoming call, the system plays the introduction - ;; for that phone number over a speaker, just as the call comes in. - ;; This helps the folks - ;; here in the house more quickly determine who is calling. - ;; and gets the right ones to gravitate to the phone. - ;; You can listen to, and record a new intro for your phone number - ;; using this menu. -exten => 4,2,Goto(s,1) -exten => t,1,Goto(s,1) -exten => i,1,Background,invalid -exten => i,2,Goto(s,1) -exten => o,1,Goto(s,1) - -[home-introduction-record] -exten => s,1,Background,intro-record-choices ;; Script: - ;; If you want some advice about recording your - ;; introduction, dial 1. - ;; otherwise, dial 2, and introduce yourself after - ;; the beep. -exten => 1,1,Playback,intro-record - ;; Your introduction should be short and sweet and crisp. - ;; Your introduction will be limited to 4 seconds. - ;; This is NOT meant to be a voice mail message, so - ;; please, don't say anything about why you are calling. - ;; After we are done making the recording, your introduction - ;; will be saved for playback. - ;; If you are the only person that would call from this number, - ;; please state your name. Otherwise, state your business - ;; or residence name instead. For instance, if you are - ;; friend of the family, say, Olie McPherson, and both - ;; you and your kids might call here a lot, you might - ;; say: "This is the distinguished Olie McPherson Residence!" - ;; If you are the only person calling, you might say this: - ;; "This is the illustrious Kermit McFrog! Pick up the Phone, someone!!" - ;; If you are calling from a business, you might pronounce a more sedate introduction,like, - ;; "Fritz from McDonalds calling.", or perhaps the more original introduction: - ;; "John, from the Park County Morgue. You stab 'em, we slab 'em!". - ;; Just one caution: the kids will hear what you record every time - ;; you call. So watch your language! - ;; I will begin recording after the tone. - ;; When you are done, hit the # key. Gather your thoughts and get - ;; ready. Remember, the # key will end the recording, and play back - ;; your intro. Good Luck, and Thank you!" -exten => 1,2,Goto(2,1) -exten => 2,1,Background,intro-start - ;; OK, here we go! After the beep, please give your introduction. -exten => 2,2,Background,beep -exten => 2,3,Record,priv-callerintros/${CALLERIDNUM}:gsm|4 -exten => 2,4,Background,priv-callerintros/${CALLERIDNUM} -exten => 2,5,Goto(home-introduction,s,1) -exten => t,1,Goto(s,1) -exten => i,1,Background,invalid -exten => i,2,Goto(s,1) -exten => o,1,Goto(s,1) - - -In the above, you'd most likely reword the messages to your liking, -and maybe do more advanced things with the 'error' conditions (i,o,t priorities), -but I hope it conveys the idea... - - |
