 A 2013 FCC analysis, described how, in some cases, long-distance calls are charged six times the rate on the outside, or in other instances, a fifteen-minute call could cost upwards of $15.It also reported that phone rates had "caused inmates and their friends and families to subsidize everything from inmate welfare to salaries and benefits, states’ general revenue funds and personnel training".At that time the FCC proposed capping the charge for interstate inmate phone calls at $3.75 for 15 minutes.
