Abstract:
1. A system for routing traffic of a subscriber associated with a first communication network comprising a visited network, the system comprising: a gateway coupled to the first communication network and a second communication network, wherein the gateway monitors roaming links of the first communication network and detects the subscriber registering a subscriber communication device with the visited network, wherein the gateway receives location information corresponding to a location of the subscriber communication device at the first communication network and a status of a client application installed on one of the subscriber communication device and a separate communication device from the subscriber communication device, capable of receiving an incoming call, associated with the subscriber being coupled to the gateway via the second communication network, wherein the gateway, upon determining a connection of the client application to the second communication network, automatically transfers the traffic directed to the subscriber communication device via the first communication network to the client application using the second communication network, and the gateway further comprising a mechanism to determine status of at least one of the client application and the subscriber communication device, wherein the first communication network is at least one of a Plain Old Telephone System (POTS) and a cellular network, and the second communication network is an IP-based network, and wherein the gateway is further configured to switch traffic between the subscriber communication device and the client application during an ongoing call.
