Sen. Mary Lazich, R-Waukesha, and Rep. Mark Honadel, R-Milwaukee, authored a bill that would prohibit tricking the call's recipient into believing the caller is someone they are not for malicious purposes.

"While use of spoofing is said to have some legitimate uses, it can also be used to frighten, harass and potentially defraud," Lazich and Honadel said in an e-mail to legislators.

The bill language forbids a caller from intentionally providing a false phone number and convincing the person receiving the call that it comes from someone other than the actual caller.

The bill would make it illegal to defraud, cause harm or wrongfully obtain any information of value from using a caller identification service to transmit misleading or inaccurate caller identification information. It would also prohibit individuals from masking their voices or providing a fake phone number to the call recipient, said Jason Vick, spokesperson for Honadel.
