API-Key Business for Blacklists
The tellows blacklists for your PBX - The perfect solution for your company
The tellows number ratings range on a scale of 1 - 9, with 1 being considered serious and 9 being extremely untrustworthy. The blacklists contain the tellows rating from 7 - 9 and thus warn you of a dubious caller as soon as the phone rings. More than 40.000 data sets and 1,3 million visitors per month enable the largest community of telephone numbers to offer you the most successful blacklists and spam filters for the telephone! Several hundred people leave their comments and ratings on the numbers they call each day - all of this is incorporated into the blacklists! Benefit from real-time synchronisation with systems like Asterisk. With the tellows API Key a live number query can be made on tellows servers. This way your protection against annoying calls is always up to date, because information about each phone number can be synchronised in real-time with the terminal device and can be processed, blocked and suppressed accordingly. Annoying advertising calls are therefore passè.
