Reporting calls for Wavecrest UK numbers

We have number ranges allocated from The Office of Communications (OFCOM), a government-approved authority for telecommunications in the UK.

We assign these numbers to other businesses who may then allocate, assign or sell them to their own subscribers. Unfortunately, some individual subscribers of these companies may misuse these numbers.

We perform due diligence on all companies that we work with, but we are not permitted to obtain details of their end-user subscribers.

If we learn of any instance of misuse or illegal activity using one of our numbers, we take immediate action through our clear 2 step process.

  1. We contact the company that we assigned the number to and instruct them to suspend the associated account and any other accounts linked to the number holder. 
  2. We also block that number on our network. However, some calls may still pass through other networks.
