The gateway server enables the enterprise to manage and control its cellular service in addition to providing a significant overall cost reduction for telecommunications. Moreover, the gateway server includes an overall platform and architecture for improved and integrated wireless enterprise solutions and facilitates convergence between the enterprise's cellular and Voice over IP (Internet Protocol) infrastructure.
The gateway server leverages the benefits of Voice over IP with cellular to extend the cellular network into the enterprise. The gateway server addresses both cellular voice and data, and is a networking solution that works together with the enterprise's existing PBX, performing mobile call control functions (routing and services).
Additionally, the gateway server bridges the enterprise PBX and public cellular environments to enable telecom applications for the cellular user, such as short-code dialing (e.g. 4 and 5-digit dialing), one number service (one phone number for the land-line and cellular phone), and single voice mail box that services both a user's land-line and cellular telephone. The gateway server enables the enterprise to leverage existing telecom assets for cellular use (e.g., least-cost routing over a corporation's VoIP or leased-lines network for discounted long distance; use of existing PBX voicemail system).
