The Federal Communications Commission could soon make it more difficult for telemarketers to leave ringless voicemails on your cellphone. On Wednesday, Chairwoman Jessica Rosenworcel shared a proposal that seeks to force callers to obtain your consent before they can leave a message directly in your voicemail box.

The proposal would effectively extend the protections of the Telephone Consumer Protection Act to cover ringless voicemails. The 1991 law prohibits telemarketers and other groups from using automated systems to make non-emergency calls to your mobile phone without first obtaining your consent. In March 2017, a company called All About the Message asked the FCC to rule that the TCPA did not cover ringless voicemails. Rosenworcel’s proposal would deny that petition.
