[anti-abuse-wg] VoIP

Reading the article in a minute !

However, as an information pointer I've some data ...

I've an VM with asterisk at home, and every day I've to ban (I use fail2ban to do it automatically after 3 failed attempts from the same IP), average about 20 IPs attempting to use my SIP service to my provider. This turns into 100 per day in the office (average).

Of course, if they succeed, they can make "free" calls that I need to pay from my pocket ... So, I report automatically those attempts (once banned), including the logs, to the abuse contacts of the IP holder.

Some of them just don't care, unfortunately, as many abuse contacts, just don't work, or the mailboxes aren't being read, or they respond that you must fill in a form.

Regards,
Jordi

    Hi,
    
    I read an interesting article this morning and I thought I should share.
    
    https://www.nytimes.com/2019/04/24/technology/personaltech/stop-robocalls.html
    
    It is interesting how the types of abuse are related to the costs, geo,
    etc as well as perceived benefits thereof. Although I have setup SIP
    and have played extensively with stuff like asterisk, I do not work
    much with VoIP abuse or have much experience with it. (which is
    probably why it is interesting to me :) )
