There are a number of steps you can take to drastically reduce the number of silent calls you receive:
Register with TPS
The Telephone Preference Service (TPS) exists mainly to combat unwanted sales calls and registering should help cut down the number of silent calls you receive.
Cold callers use predictive diallers to make vast numbers of calls which are then allocated to call centre staff when you answer the phone.
They often generate such a high number of calls that when you answer, there is nobody available to take your call and the line is silent.
It is free to register and unwanted calls should stop just 28 days after registration is complete.
TPS will let you:
Stop unwanted telephone marketing calls
Stop unwanted text messages
Prevent calls at inconvenient times
Allow valid calls to get through
Stop calls about products you have no interest in
Find out who is calling
UK companies are required by TPS to display their phone number so it is easier for you to report unwanted calls from the same number.
To check the number of the call:
Screen the call using your handset and make a note of the phone number, along with the date and time of the call
Dial 1471 if you missed the call and record the phone number and the time the call was made
You can then report the company to the Information Commissioner's Office who will investigate and potentially issue fines for unwanted cold calls.
If a call centre is owned by a UK registered company, it will still have to display its phone number even if the callers are based overseas.
Report silent calls to Ofcom
You can report silent calls or abandoned calls to the telecoms regulator Ofcom so that they can investigate further.
To complain about a silent call:
Visit the Ofcom website
Enter details about when you received the call
Confirm what number it came from
Report a recorded message or silence on the line
If Ofcom needs more information about your complaint they may contact you, but in most cases this is unnecessary.
Report intimidating calls
If you believe the calls you are receiving are from an individual who is deliberately trying to intimidate you, you should contact the police.
To find contact details of your local police station or neighbourhood policing team visit the Police.UK website.
