Let tellows mellow your day - thanks to the spam filter for you telecommunications system.

These lists contain all active telephone numbers that have been rated with a tellows score 7 or higher reported on tellows.co.uk . If your telecommunications system (TS) is based i.e. on Asterisk or something similar, simply download the list and import them into you TS' phone book. The license runtime of the blacklist is 2 years.

The tellows score works on a scale from 1 (trustworthy) to 9 (dubious). However, these score lists contain only those numbers rated with 7 and higher to warn you against potential threats on the first ring of your telephone.

More than 40.000 data sets and 1,5 million users per month provides tellows with means to offer you an efficient call blocker and spam filter. Hundreds of users comment and rate numbers on a daily basis - that's all part of the score list.

However, telecommunications systems such as Asterisk will reap the greatest benefits due to the real time sync to tellows severs with the tellows API key. Thanks to the key, a live query is submitted to our servers the second your TS receives a call. From there it is up to you what the TS is supposed to do with the call - block it or process it any other way you prefer. Thanks to the real time sync your spam filter is always up to date. From now on nuisance calls are a thing of the past. If you are interested in the API key contact us: [email protected]

If you have questions do not hesitate to ask. We are also looking forward to you feedback.

These lists are not allowed for any commercial usage. If you are interested in doing so, do not hesitate to contact us. Further information about the commercial API usage you will find here: API Partnership Program.
