Abstract
A communication system to handle call-back calls from emergency services to callers comprises a communication network and a call processing system. The communication network is configured to receive an emergency call for an emergency service from a communication device operated by a caller, and receive an incoming call for the communication device. The call processing system is configured to, in response to the emergency call, modify call controls associated with the caller, and process the modified call controls associated with the caller to determine if the incoming call is allowed. The communication network is further configured to connect the incoming call if the incoming call is allowed, and to block the incoming call if the incoming call is not allowed.
