Universal call control systems and methods

Methods and systems for providing a user with control over telecommunications services provided by a service provider. Using almost any type of communications device, a user may gain access to, view, and make changes or modifications to profile information related to the services. The changes may be made quickly and efficiently, but accuracy and thoroughness in the implementation of the changes are not sacrificed. Further, the changes to the communications services are implemented almost immediately and without involvement by the service provider. Particularly, profile information about the telecommunications service is stored on a server in a data network. A change action relating to the profile information may be received at the server from a data device (such as a wireless unit) operating on the network. The change action is implemented on the profile information to result in changed profile information, which may be provided from the server via the data network to the telecommunications system.
