Abstract

An emergency call practice application can execute on user equipment (UE) to allow users to practice dialing 9-1-1 or other emergency numbers. In a network practice mode, the emergency call practice application can initiate a practice emergency call by sending a call setup message to an IP Multimedia Subsystem (IMS). The IMS can route the call setup message to a Public Safety Answering Point (PSAP) routing server, which can recognize a destination identifier in the call setup message as being associated with a test server instead of a PSAP. The PSAP routing server can forward the call setup message to the test server to connect the practice emergency call.
