Abstract:
A call method, a device, and a communication system for a private branch exchange (PBX) user are provided. User data of the private branch exchange user may be sent to an application server when the private branch exchange user has opened an account but not registered. The application server may continue normal calling by using the user data of the private branch exchange user. The PBX user can make a successful call without independent registration when implementing independent supplementary services.
