Once an inmate receives his housing assignment, he may contact family and friends from phones inside the facility, if the recipients are willing to accept the charges.

Inmates cannot receive incoming telephone calls and MSO employees are not permitted to deliver personal messages to inmates. 

If you are having trouble receiving calls from an inmate at the Middlesex Jail & House of Correction, would like to request a Block or Unblock on your phone, or have a question about how to setup a direct bill or prepaid account, please contact Securus Technologies at 1-800-844-6591 or online at

Please note, all calls are subject to recording and monitoring and may be used in a court of law.
