Embodiments herein disclose methods and systems for detecting call spoofing in a telecommunication network. The system includes a memory , at least one processor , a call spoofing controller connected to the memory and the processor configured to: create a mirror of signaling protocols for an incoming call from first a user device . The call spoofing controller is further configured to determine if a caller phone number belongs to a network operator using a source Internet Protocol (IP) address in an incoming INVITE/Iniytial Address Message (IAM). The call spoofing controller is further configured to determine the incoming call as a spoofed call, if the source IP address does not match a Session Border Controller/Service Switching Point (SBC/SSP) of the network operator.

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.

A mobile application gateway configured to interconnect mobile communication devices on a cellular network with an enterprise network is provided. The mobile application gateway includes a voice and data signaling gateway configured to provide routing functionalities, service functionalities and admission control. A gateway GPRS support node (GGSN) is configured to establish a secure data session between one or more of the mobile communication devices and the enterprise network by establishing a GPRS tunneling protocol (GTP) tunnel between a carrier-hosted serving GPRS support node (SGSN) and the GGSN.
