Voice spam is a significant problem worldwide. In this paper, we observe some aspects of the voice spam ecosystem in Europe using a telephony honeypot with 800 phone numbers from 8 European countries over a period of 3 years. Unlike previous honeypots, the numbers were never assigned to a real user before being added to the honeypot. The specific nature of this honeypot allows us to focus on illegitimate calls. Indeed, as the numbers were never used by real users, no consent to telemarketing has ever been given. In particular, we present an experiment we conduct on National Do-Not-Call (DNC) lists and the effects of registering to such lists. We find that the phone numbers added to DNC lists receive a lower number of spam calls both in Spain and the UK. However, we also show anecdotal evidence that the DNC list in the UK is abused by spammers. Finally, we discuss the effectiveness of DNC lists by reviewing various implementation challenges and comparing the existing approaches.
