Prisoner Telephone System

Secure, controlled calling for people in prison, on secure devices and on wall phones.

Robust. Reliable. Built for custody.

Calling on Secure Devices

Socrates Connect brings calling to our locked-down phones and tablets: a modern, flexible alternative to traditional in-cell phones and on-wall wing phones. People can reach their approved contacts from the same secure device they already use for education and support, without queuing for a shared phone.

Every call keeps the controls of a traditional prison phone system: calls are monitored, recorded and restricted to pre-approved contacts.

  • ● Two-way text messaging
  • ● Recent call history showing number called, duration and cost
  • ● Call credit balance updated in real time
  • ● Headphone or speakerphone use

Recording & Monitoring

Our software manages every prisoner call, whether it's made on a secure device or a wall phone.

  • Live recording and monitoring of calls
  • Configurable allowed and blocked number lists
  • Detailed usage reports to track call activity and spot misuse
  • All data stored within your country, to meet local regulations

Indoor Prisoner Phone System

Our entry-level wall phone system: a reliable, cost-effective way to give people in prison controlled access to shared phones. It's quick to deploy and fits into existing daily routines.

  • ● Limits on call duration and frequency, to keep phone use fair and orderly
  • ● Free calls to specified numbers
  • ● Analogue or VoIP phones
  • ● Easy to use, even for people with little technical experience

PIN Phone System

For individual control over each prisoner's calls. Every prisoner has their own PIN and account, so shared wall phones can still be tracked and billed person by person.

  • ● A unique PIN for each prisoner, preventing unauthorised use
  • ● Individual accounts that track each prisoner's call activity and costs
  • ● Prisoners or their families can add funds securely
  • ● Per-prisoner reporting and analytics to identify potential misuse
