Abstract: A method may include determining that a digit pattern has been input on a user device to initiate a call; transmitting the digit pattern to a device that stores a list of digit patterns to which calls are not to be completed; receiving, from the device, data that indicates whether the digit pattern is on the list of digit patterns; prohibiting the call from being initiated with a network when the data indicates that the digit pattern is on the list of digit patterns; and initiating the call with the network when the data indicates that the digit pattern is not on the list of digit patterns.

Abstract: A device may determine that a failure occurred in an emergency call between a public-safety answering point (PSAP) and a first user device associated with an emergency caller, and may identify, based on determining the failure, one of a first option, a second option, or a third option for redirecting an emergency callback to a contact of the emergency caller. The device may cause, when the first option is identified, the emergency callback to be redirected to a second user device associated with the contact of the emergency caller, and may cause, when the first option is identified, a bearer path to be established between the PSAP and the second user device for the emergency callback.
