marklyon writes: HB 872, recently signed into law by Mississippi Governor Haley Barbour, makes Caller ID spoofing illegal. Alterations to the caller's name, telephone number, or name and telephone number that is shown to a recipient of a call or otherwise presented to the network. The law applies to PSTN, wireless and VOIP calls. Penalties for each violation can be up to $1,000 and one year in jail. Blocking of caller identification information is still permitted.
