every weekend this number calls my house ..why can people not find out who is doing it and stop it?

by that do you mean that the calls from this number will be dialed to our number, and then automatically forwarded to the number they are trying to reach, without us noticing, and then when the phone bill comes in, it will cost us?

This is a payphone in the Harris county jail,I received this call today. Be Careful when answering and accepting, inmates will try to get you to forward your calls to a cellphone, sometimes a girlfriend or family member, they call you number back, now forwarded and rack up collect call charges.
