Abstract:
Methods, systems, and computer program products for routing a call from a 2G network to a dual mode 2G/session initiation protocol (SIP) device are disclosed. According to one method, a 2G mobility location information query message requesting mobility location information for delivering a call to a dual mode 2G/SIP device roaming in a SIP-based network is received at a communications signal message routing node, wherein the mobility information query message includes a destination subscriber identifier associated with the dual mode 2G/SIP device. SIP mobility location information is determined based on the destination subscriber identifier and the SIP mobility location information is provided to the query originator.
