WASHINGTON (AP) — A decade after families of prison inmates asked for action, the Federal Communications Commission agreed on Friday to limit how much companies can charge for phone calls made from behind bars.

The FCC voted 2-1 during an emotional meeting to cap interstate phone rates at 21 cents a minute for debit or prepaid calls and 25 cents a minute for collect calls. Companies wanting to set higher rates would have to file a request for a waiver and could not charge more until that waiver is granted.
