SOLVED TrueCNAM: The Spammer's Worst Nightmare

TrueCNAM: A Breath of Fresh Air for CNAM Lookups and CallerID Superfecta

Today, we’re pleased to introduce a new CNAM service, TrueCNAM, that strikes what we believe is a fair balance between free and incredibly affordable commercial tiers with appeal to a broad cross-section of the VoIP community. In addition, James Finstrom has introduced a CallerID Superfecta module for TrueCNAM making it easy to implement and configure.

In addition to CNAM lookups, TrueCNAM has another awesome feature. TrueCNAM adds a SPAM scoring mechanism called TrueSpam which assigns a numerical score (0-100%) assessing the likelihood that the incoming caller is a spammer.

I signed up for the free account. Not very impressed so far with whatever database they're using for lookups. Spent my 25 free lookups testing and a lot of nbrs which existed in OpenCNAM, Whitepages, 411info, Yellowpages, Google came up blank with truecnam. I even tried phone nbrs of major hotels and corporations in NY and not much better either. Maybe its just the nbrs I'm using to test. Hopefully they will improve or maybe they're just looking for sign-ups to harvest their database!!

Hate to say the I saw the same. Out of 25 attempts I had ZERO hits with TrueCNAM.

I tried the last 23 entries from the business pbx CDR with real CNAM results(a mix of business and personal), one call center ("ATLANTA NW") number and one "WIRELESS CALLER" number. TrueCNAM did not return ANY information at all, not a single name, region, call center.

I can't imagine why anyone would use the service.

One good reason would be to rid your phones of spammers.

TrueCNAM does not dip into the LIDB, thus the actual CNAM component (well, the whole thing, actually) relies upon community contribution. I find this to be a little disingenuous, since it calls itself CNAM, which almost everyone associates with LIDB lookups.

That is the problem. It is a spam only service wrapped up as something more, you have to dig into the FAQs to see there is no normal CNAM service. Most businesses would rather accept the spam than take any chance at all of missing a legitimate call.

But, if someone gets enough spam calls it could be worthwhile. I'll probably install the module at a site or two to see if there is enough benefit to consider.

I'm getting the response "TrueSPAM disabled." TrueCNAM tells me this is not one of their error messages.

Did you uncheck the TrueSpam box when you set up TrueCNAM in CallerID Superfecta??

No, there is a problem.

There are some "TrueSPAM" vs "TrueSpam" inconsistencies in the posted code. Normalize the case in lines 38/55/69 and it works.

Also, the tutorial shows the main CID Superfecta SPAM Send Threshold value as 3, it should be 1 unless there are other spam sources in the mix.

I haven't been able to get the superfecta "SPAM Text" setting to work, but I think that's an issue with superfecta itself and not the module.

EDIT: Spam Text appears to work for Multifecta mode, but not Singlefecta.

 

[jerrm]

There is an improved and functioning version of the module from @lgaetz posted in the comments of jfinstrom's gist: https://gist.github.com/jfinstrom/d0ac832e9c46e6f8c2e9

Scroll down to the last comment, replace the contents of /var/www/html/admin/modules/superfecta/sources/source-TrueCNAM.module with @lgaetz's post.

 

[wardmundy]

@jerrm Fixed. Just run through the install steps again to update.

cd /
wget http://incrediblepbx.com/TrueCNAM.tar.gz
tar zxvf TrueCNAM.tar.gz
rm -f TrueCNAM.tar.gz

Also updated tutorial to change SPAM Threshold setup from 3 to 1. Thanks.

 

[rcoates]

Thank you for the community input and resolving this issue. This is a good example of the open source community working together to fix issues. Much appreciated.

Thanks leon

I did a tail of the module and then reloaded the superfecta page and now the module showed up!

 

[wa4zlw]

i setup intercept and it we wondered why we werent receiving calls. Calls were being redirected to the spam extension and the spam score was <80 so I turned it off until we figure out what's going and what is wrong :-(

 

[shdwkeeper]

Does this still work for IPBX 2020? Also I know there is a script out there as well that grabs this CallerID info and it auto populates your Asterisk Phonebook, can't get that to work wither with the 2020 build. Any ideas?
