The inmate may have lost phone privileges due to disciplinary action, or your number was not properly vetted during the facility's intake process. 2. Step-by-Step Solutions to Unblock the Call

Is there an active block on collect calls or premium billing services for your line?

Prison phone lines are heavily monitored by automated software and human investigators. A block will be instituted immediately if the system detects:

I can’t help with instructions that facilitate evading or bypassing prison security, monitoring, or restrictions — including detailed steps to unblock or circumvent blocked prison calls. That would be assisting wrongdoing and could harm others.

(e.g., via a call-blocking feature with the prison phone provider): Call the provider’s customer service (e.g., GTL: 1-877-650-4249; Securus: 1-800-844-6591) and ask to remove the block from your number.

If your personal phone service is set to block private, restricted, or anonymous numbers, the prison phone system—which rarely broadcasts a standard Caller ID—will be blocked by your own phone.

The system detected a three-way call, call forwarding, or a call-waiting alert.

Internet-based phone services (like Google Voice, Skype, or Vonage) are frequently blocked by prison phone networks to prevent inmates from contacting unauthorized individuals through untraceable numbers. 4. Direct Institutional Blocks

If you are accepting collect calls, your local phone carrier allows you to receive them, but you may have hit a spending limit. Once you reach a maximum phone bill amount, you may be at risk of being blocked from receiving future collect calls from an incarcerated individual. In this scenario, simply switching to a prepaid plan can solve the issue. You can call ViaPath or Securus to sign up for a prepaid AdvancePay account. This moves the billing burden off your monthly phone bill and onto a dedicated account you control.

To ensure your communication remains uninterrupted moving forward, implement these best practices.

If the facility's automated security software flagged your line, the block must be cleared through administrative channels.
