A method for handling call originations is provided. The method includes sending origination information from a mobile device to an application server in an enterprise network using Short Message Service (SMS) and determining whether a hotline feature is present in a subscriber profile associated with the mobile device. Data is then routed from the mobile device to a predetermined destination based on the hotline feature.

A method of operating a network server, such as a mobile application gateway, connect devices on a cellular or carrier network with individual networks, such as enterprise voice and data networks or residential networks. The effects of the present invention are far reaching in terms of transferring effective call control from the cellular network into the control of the individual network, such as the enterprise, and enabling new business models for the purchase of cellular service from a public cellular carrier by an enterprise.
