    摘要: Emergency call backs may be placed to a user device in a manner that bypasses certain features (e.g., call forwarding) that may be enabled by the device. A method may include receiving an emergency call from a user device; and creating, in response to the emergency call, an emergency session associated with the user device, where the creating includes forwarding the call to a public safety access point (PSAP) server that handles emergency calls. The method may further include receiving a call, such as an emergency call back call, destined for the user device; determining that the emergency session has not expired when an elapse time associated with the emergency session is less than a threshold; and forwarding, to the user device, the call, as a return call from the PSAP server, based on the determination that the emergency session has not expired.
