I doubt the legitimacy of this call. Maybe for county jails? I know a federal inmate and he has fo establish and account and fund it, no collect calls and numbers shows as unavailable when he calls. I would NOT give out my credit card number unless you speak to whoever is calling in person. I think there may be a breach with a legit call system in which these scammers have gotten numbers and access to recordings of inmate names. If I am wrong, sorry but seems very fishy to me.
