1. The line is busy due to a large number of calls: As a public institution, the prison may receive a large number of calls, including family members seeking help, lawyers consulting and social concerns. These incoming calls may cause the line to be busy, which may cause others to call in and cannot be connected.

2. Don't answer the phone: The prison may have set certain conditions, such as only answering the phone of a specific time period and a specific person, or restricting contact with the outside world.

3. Telephone failure: The telephone system may encounter failure or maintenance, which makes it impossible to connect.
