There are several ways to receive calls from inmates, including collect, prepaid collect, and inmate debit calls. Inmates have the option of placing collect calls to telephone numbers approved by the correctional facility. Collect calls are billed to the called party every month through their phone carrier company.
If you receive a high number of collect calls, you may have reached the billing limit allowed by your local phone company. Once you reach a maximum phone bill amount, you may be at a risk of being blocked from receiving future collect calls from an inmate. In such instances, you can call Global Tel*Link at 866-607-6006 to sign up for a prepaid calling account and begin receiving calls again. In addition, online account registration and deposits are available through

You can sign up for a prepaid calling account today if you experience any of the following:

  • You have a collect call restriction by your local phone provider
  • You have exceeded the collect call limit
  • You are unable to receive inmate calls on your cell phone, office phone, hospital phone or other commercial phone numbers
  • Your local telephone company does not bill for inmate collect calls
  • Your phone number is blocked from receiving inmate collect calls
  • You have a high collect call bill and want to manage your calling budget

Please note in order to receive calls to cell phones, inmates must call either prepaid collect or use their inmate debit calling account.

There are multiple ways to block calls from inmates as needed. Any incoming call can be refused at any time by hanging up. The call will be disconnected and the inmate will be informed their call was not accepted.
Any incoming call can be blocked permanently from a correctional facility by pressing “7” when prompted.
You can also call the GTL customer service department at 866-607-6006 and they will be able to help block future calls from a facility.

You can remove a block on your telephone number by calling the GTL customer service department at 866-607-6006.

Please note there are other reasons why your phone number may be blocked from receiving collect calls from correctional facilities. These include:

  • Your local telephone company does not offer billing on collect calls
  • You have reached the maximum dollar amount limit allowed for collect calls
  • You are trying to receive collect calls on a cell phone or work phone

CDCR Inmate Telephone Information

On July 11, 2016, Davidson County (TN) Sheriff Daron Hall announced the culmination of negotiations with Global Tel*Link (GTL), implementing some of the lowest inmate phone call rates in the nation and the lowest in the state for inmates in Davidson County correctional facilities.

Sheriff Daron Hall has long maintained his commitment to lower inmate calling rates, stating that decreasing the financial burden on inmates and their families is paramount to ensuring inmates receive family support which has been shown as a key factor in reducing recidivism rates.

Research agrees with the Davidson County Sheriff, repeatedly demonstrating increased communication with loved ones helps to maintain community ties that are crucial to reducing the probability of recidivism.

In a press release announcing the new calling rates, Sheriff Hall applauded his county’s partnership with GTL, stating “[t]he phone service provider, Global Tel*Link (GTL), has proven to be a fantastic partner by ensuring we receive the service needed and, at the same time, get a contract in place that accomplishes the goal of assisting inmate families”.

In addition, inmate advocates applauded the Sheriff for his leadership in lowering calling rates and the county’s choice to divert from a commission-based model to ensure inmates can easily communicate with their friends and family members.

This recent announcement further demonstrates GTL’s commitment towards reducing recidivism by allowing inmates to maintain a connection with their support systems, such as friends and family members, while serving out their sentences. GTL is proud of being associated with the efforts of our partners in the Davidson County Sheriff’s Office and is committed to providing similar service and industry leading technology for correctional facilities of all sizes across the United States.
