Is there any simple tele market blocking device that can be used with any key system
thanks gary s.

Blocking calls from telemarketers at the CPE-level is a Herculean task.

I don't know how it can be done. Predictive dialers can spoof both working and non-working telephone numbers. Even then, the dialer equipment, which at one time may have listened for the SITs to determine if a number is working or not, now looks for Answer Supervision.

I recently came across a still functional TeleZapper TZ-900 that I purchased back in the 90's. I tried connecting it to the line input on my Partner ACS. I heard the familiar tones when going off-hook and when the auto attendant answers calls. Of course, it didn't make a dent in the number of telemarketers calls I receive.

Service providers (LECs & IXCs) will need to step up their game (assuming the want) to actually block Spam calls.

The FCC offered some tips to consumers when they do receive a robocall:

Don’t share. Do not provide any personal information to anyone who calls you unexpectedly.
Be aware. Telephone scammers are good at what they do and may use real information to gain your trust and imply that they work for a company you trust.
Use Caller ID. Criminals might use “spoofing” to deliberately falsify the information transmitted.
Double-check. If you think it might be a legitimate call, hang up and call the company with which you have an established business relationship using a phone number from a previous bill or on their website.
File a complaint with the FCC.


I have been on the Federal and State Do-Not-Call list (like most sensible people) since it was first made available. I also file a complaint with the FCC...guess what? They still happen and those lovely text messages as well.

My dad answers every single one of those calls, despite my warning when I'm sitting right next to him. Once, he said "but they're calling from a 488 number, so they must be a neighbor". He's already been scammed out of thousands of dollars in gift cards, but he keeps on going. Thankfully, the manager of the local Walgreen's store noticed the pattern of his gift card purchases and put out a store-wide alert to stop selling these to him.

What people also don't understand is that by actually answering these calls and even worse, engaging in conversation with them, you bump yourself up to the next level with your name/number being shared or sold to even more scammers. It will NEVER end as long as seniors keep falling for their games.

I noticed the call volume by these idiots has dropped tremendously in the last 2 weeks. Supposedly the enforcement has stepped up but who knows. Next wave will be the robotexts. What chaps my ass is the FCC has fined violators in the millions of dollars but collected just over $6K. What a joke. No teeth to their bite.

The problem with their "bite" is that it's hard to enforce US laws in foreign countries, which through the f'n magic of VOIP, is where they are located. It's only the ones who are operating within the US that can really be fined with any hope of collecting a dime. I guess that they nabbed six of them. Woo hoo!

Ya SIP lines are like the damn Herpes of the industry anymore with spam calls. Something really needs to be done about the spoofing. They need to lock it down to only numbers you can prove you own.

Well, they did lock this down for operations within the US, but most of these scam artists operate outside of our jurisdiction, like in the Caribbean, or in the middle east. To add insult to injury, they got my dad for about $500.00 in reverse toll charges for their calls to him. You know how when they call, you always have to say 'hello' twice before they come on the line? Well then, they ask if this is Mr. XXX, act like they can't hear so that he says "yes" again. They then record his having said this when the collect call scam operators can log it as an accepted collect call and bill back accordingly. They are smart, really smart, and our system is full of holes to allow this stuff to happen. Yes, VOIP is the culprit here. Despite its advantages, it also provides a wide-open gateway to con artists.

If I was gutsy enough, I'd answer a telemarketer by saying "For security reasons, this call is being recorded. Please disconnect if you do not wish to be recorded"...or something along those lines. Curious if that would cause them to hang-up.

If its a number I don't know I answer "help desk can please have your name and terminal number". The call usually disconnects before I get thru the sentence. The only ones that won't drop are the recorded ones asking me to press a key to talk to a " credit card fraud investigator" or some US government agency about an arrest warrent. I don't think they want to take the time to customize their scripts for when they call up here in Canada.

on My ESI phone system at home...its real Easy to stop unwanted tele marketing calls all day long.
i set up the auto attendant to answer all calls with the messgage to press 1 to continue , or stay on the line to disconnect. I can still see the callerid on my TV screen but 99 percent of the callers drop off right away( the disconect timer is set for 15 seconds) and with the ESI , the Auto Attendent is built in.

With my Avaya Partner ACS & Partner Voice Messaging, I allow the auto attendant to grab all incoming calls.

The PVM is a bare-bones system so I'm a bit limited on what I can do. I purposely made my auto attendant greeting long winded, so most telemarketing calls drop during the message. The few that manage to hold on will be transferred to x10 but disconnect shortly after that.

If I'm watching television, I'll see the incoming call data appear on the screen. The Caller ID banner will appear on x10's display.
