A Birmingham MP has called for a new system which could end the menace of silent calls.
Informative messages would identify the caller to the person answering via a recorded message, and explain the reason for the call.
They could replace the "silent calls" generated by automated dialling systems used by call centres for marketing purposes.
John Hemming, Liberal Democrat MP for Yardley, said the new approach could reduce the anxiety of receiving a silent call.
Nuisance calls where the person hears a silence on the other end are often generated by automated dialling systems used by call centres.
About 160,000 complaints about nuisance calls are made to telecoms companies each month although the actual volume received is not known, Ofcom said.
Mr Hemming said: "This is the beginning of the end for silent calls. The gradual introduction of informative messages to replace silence will reduce the anxiety caused by calls that are silent."
