Abstract
A controlled-environment facility communications management system, and/or the like, receives an indication of an electronic communication request with a telephone number initiated by, or to, a resident of a controlled environment facility. The controlled-environment facility communications management system, and/or the like, accesses a line information database and determines, based on the contents of the line information database, whether the telephone number is an Internet Protocol (IP) telephone number. The controlled-environment facility communications management system, and/or the like, takes action with respect to the electronic communication in response to identification of the telephone number as an IP telephone number.
