I just paid for inmate aid phone time. but when my son calls it says IC Solutions . Will my funds pay for this call?

No, InmateAid does not replace ICSolutions, they make the calls through ICSolutions less expensive because of the phone number used. Monopoly providers can charge whatever they want as they are not competing for price supremacy. Since the carriers post their rates, InmateAid uses that information and then finds the cheapest phone number to make those calls with.
