Modifies provisions relating to electronic communications

HB 509 updates Missouri's rules for phone calls and caller ID. It creates a state-run "no-call list" managed by the attorney general, allowing residents and businesses to opt out of unwanted telemarketing calls. The bill bans "call spoofing" (faking caller ID to defraud or harass) and defines terms like "telephone solicitation" to clarify what types of calls are restricted. It directly affects consumers who can register to block calls and businesses that must comply with the new rules when contacting Missouri residents. The law replaces outdated sections with these new provisions to modernize telemarketing regulations.
