Abstract

A mobile device utilizes a two-stage dialing solution when roaming on a visited mobile operator (MO) network to implement centralized routing so that a home network portion of a hybrid network is inserted into the path of outbound calls. A remote centralized routing (CR) service interoperates with a CR client on the mobile device. When a call is initiated to a remote party, the CR client calls into an arbitrary roaming routing number that is terminated in the home network. Once the call is connected between the mobile device and home network, the CR client sends a dialing string that includes a destination number of the remote party. The CR service calls the destination number and then bridges the calls to the mobile device and remote party to establish an end-to-end call path between the local and far ends of the call that traverses the home network.
