If you missed a call from someone in jail or prison and you’re wondering why you can’t call an inmate back, the short answer is that the facility’s phone system only works in one direction. Inmates place outgoing calls from a controlled system; the numbers those calls come from don’t accept incoming calls, and the facility switchboard won’t patch you through to a housing unit. Your only option is to wait for the person inside to try you again, and to make sure the next call actually connects.
Why the Phone Only Rings One Way
Every correctional facility routes personal calls through a controlled Inmate Telephone System that allows outgoing calls only. The incarcerated person requests phone time, dials from a pre-approved list of numbers, and the call either goes through or it doesn’t. Federal Bureau of Prisons policy requires all personal calls to move through this system and specifically prohibits inmates from working around it through call forwarding or similar tricks.1Federal Bureau of Prisons. Program Statement 5264.08 – Inmate Telephone Regulations State prisons and county jails follow the same basic model.
The numbers that show up on your caller ID belong to the contracted phone provider, not to the inmate or the facility, and they’re typically blocked or unlisted. Dialing them back won’t reach anyone. Calling the facility’s main line and asking to be connected won’t work either. There is no voicemail. There is no callback feature. The design is deliberate, because facilities have to control who inmates speak with, when, and for how long.
What to Do Right After a Missed Call
You can’t undo the miss, but you can make the next attempt more likely to reach you.
- Check your call log and blocked-calls list. Phones sometimes flag calls from correctional providers as spam. If you find the number there, unblock it and add it to your contacts so you recognize the next ring.
- Confirm your prepaid account is funded. If your balance runs out, the call won’t connect even when you pick up. A missed call is sometimes really a rejected call because the account was empty.
- Send a message through the facility’s electronic messaging system if one is available. A short note letting the person inside know what hours you’ll have your phone on hand is the fastest way to sync up the next attempt.
- If messaging isn’t available, write a letter with your schedule. Postal mail is slow but reliable.
- Keep your phone with you during the hours the inmate has phone access. Ask what those hours are the next time you talk, because they vary by facility and by housing unit.
Phone time inside is limited and often crowded. The person calling you may be competing with dozens of others for the same handsets, and if they used their allotted time trying you, they may have to wait through a cooldown before the system lets them dial again. Patience helps. A funded account and a phone in your pocket help more.
Make Sure You Can Actually Receive the Next Call
Two things have to be true before an inmate’s call will connect: your number has to sit on the inmate’s approved contact list, and in most cases you need a funded prepaid account with the facility’s phone provider.
The Approved Contact List
Inmates submit a list of phone numbers for approval by facility staff. Federal prisons allow up to 30 contacts.2U.S. Department of Justice Office of the Inspector General. Special Report – Review of Federal Bureau of Prisons Telephone Regulations and Practice State facilities and jails set their own limits, sometimes as low as ten. Approval can take days or weeks, and until your number is active, no call will get through no matter what you do on your end. If you recently changed numbers or the inmate was recently transferred, that’s often the reason calls stop coming.
The Prepaid Account
Correctional facilities contract with specialized telecom companies for inmate calls. The two largest are Securus Technologies and ViaPath Technologies, which was Global Tel Link (GTL) until a 2022 rebrand.3ViaPath Technologies. GTL Becomes ViaPath Technologies, Launches Expanded Reintegration Services The facility’s website usually names the provider, or you can call the facility and ask.
Securus’s prepaid product is AdvanceConnect. ViaPath’s ConnectNetwork platform offers AdvancePay and PIN Debit accounts. Setting up an account typically requires your phone number, the inmate’s ID number, and the facility name; you can register online, through the provider’s app, or by phone.4ConnectNetwork. AdvancePay Deposits by credit or debit card generally post immediately.5ConnectNetwork. PIN Debit
Prepaid receiving accounts are almost always cheaper than accepting collect calls, which carry per-call transaction fees of up to $3.00 through an automated system or up to $5.95 with a live agent.6Federal Communications Commission. Incarcerated Peoples Communications Services Under FCC rate caps in effect for interstate and intrastate calls, per-minute charges range from about $0.11 in prisons up to $0.19 at the smallest jails, inclusive of a $0.02 facility fee.8eCFR. 47 CFR Subpart FF – Incarcerated Peoples Communications Services
Other Ways to Reach Someone Inside
Because you can’t initiate a call, the tools that let you communicate on your own schedule are worth setting up even when phone calls are working.
Electronic Messaging
Federal prisons use CorrLinks. The inmate adds your email address to their list, you get a registration link, and once both sides are set up you can exchange text messages, though staff review can cause delays. CorrLinks offers a free browser-based service and an optional premium tier at $6.00 per year. Many state facilities use messaging platforms from Securus or ViaPath, where messages typically cost $0.25 to $0.50 per “stamp.”7Securus Technologies. Securus Technologies – Receive Calls, Messaging, Video and Help Messaging is the single best tool for coordinating the next phone call, because you can send a note about your availability without needing to be free at the same instant.
Video Visits
Many facilities offer video visitation from home through the provider’s website or app. Unlike phone calls, video visits are scheduled in advance: you book a slot, the inmate accepts, and both parties log in at the appointed time. FCC rate caps apply, though per-minute rates run higher than voice.
Tablets
A growing number of correctional systems issue tablets to incarcerated individuals for messaging, limited media, and in some cases voice and video calls from the housing unit. A tablet means the inmate doesn’t have to wait in line for a shared wall phone, which usually makes calls easier to time. Per-minute rates and messaging costs still apply, and facilities can restrict tablet use as a disciplinary measure.
Postal Mail
Letters remain the most reliable fallback when nothing else is working. Include the hours you’re reachable so the inmate can plan around them.
What to Expect When the Next Call Comes In
When the call connects, you’ll first hear an automated recording identifying it as coming from a correctional facility and naming the inmate. You then choose to accept or hang up. FCC rules require the provider to identify itself and disclose how you can find the per-minute rate before the call connects, and you can terminate at no charge before accepting.6Federal Communications Commission. Incarcerated Peoples Communications Services
A few things are worth knowing before you pick up:
Calls are timed. Federal prisons set a standard 15-minute call length, though the warden can adjust it.1Federal Bureau of Prisons. Program Statement 5264.08 – Inmate Telephone Regulations State facilities set their own limits, some up to 30 minutes. When the timer runs out, the call ends. There is usually a waiting period before the inmate can dial again.
Calls are recorded. Wardens are required to establish monitoring procedures, and inmates are notified their calls may be listened to.9eCFR. 28 CFR 540.102 – Monitoring of Inmate Telephone Calls Properly placed attorney calls are the exception. Anything said on any other call, by either party, can be used in a criminal case. Continuing to talk after the warning counts as consent. Speak accordingly.
Call waiting and three-way calling will drop the call. Facilities prohibit these features during inmate calls, and the phone system detects them.2U.S. Department of Justice Office of the Inspector General. Special Report – Review of Federal Bureau of Prisons Telephone Regulations and Practice Even an innocent incoming call-waiting beep can cut the line. If you can turn call waiting off on your phone, do it before the next expected call.
Disconnections happen. Technical glitches, facility lockdowns, and the time limit itself all end calls. If a call drops, the inmate can try again if they still have time and available funds, though the cooldown period may mean a wait.
You can also permanently block calls from a facility using the prompts during an incoming call. Unblocking later can be a hassle, so use that option carefully.
Missing an inmate’s call is one of the most common frustrations families deal with, and the system offers no shortcut around it. The next call is coming when the person inside can find an open phone. Your job between now and then is to have your phone in reach, your account funded, and a message waiting that tells them when you’ll be there.
