Abstract
A first communication network transfers a signaling message for a call to a second communication network. The signaling message indicates a first identifier that represents a connection through the first communication network to the second communication network. The second communication network processes the signaling message to select a second identifier. The first communication network transfers a user communication for the call to the second communication network. The user communication has a header indicating the first identifier. In response to the first identifier, the second communication network modifies the first identifier in the header to the second identifier. The second communication network transfers the user communication to a destination node in response to the second identifier in the header of the user communication.
