Abstract
Methods and systems are provided for establishing calls to wireless directory numbers (DNs) in a telecommunications network. When a call is directed to a wireless DN, a first node in the network identifies a signaling node associated with the wireless DN and sends the identified signaling node a request for a route to the wireless DN. If the wireless device associated with wireless DN is outside of its home area and is served by a visited node in the network, the signaling node determines a route that excludes the home node associated with the wireless DN and returns a temporary location directory number (TLDN) to the first node. Using the TLDN, the first node then establishes a connection to the visited node.
