Abstract
Communication systems and methods suitable for use in a Multiple Line Multiple Device service environment, involving a native line and a second shared line, are disclosed. Logic at one or more nodes and application servers is configured to ensure that network handover data, or other information, is only updated for the native line registration but not the shared line. Then when a call is placed or received on the shared line, the call is anchored to the native line based on that network handover data. If, during that call, a request is received to handover the call from a first network having a first communication protocol to a second network having a second communication protocol, the handover occurs based on the anchored native line. In one example embodiment the first network is a Packet Switched network and the second network is a Circuit Switched network.
