Abstract: A system and method for correlating messages from A interface links is disclosed. When an initial connection message for a new call connection is detected, a new anchor record and call record are created to capture messages for that call. When an initial handover connection is detected, a handover pending record is created to collect messages related to the handover connection. When either a handover-from or handover-to connection is detected, a handover connection reference record is sent to a rendezvous processor. Handover-to and handover-from connection reference records are correlated in the rendezvous processor by matching data keyed to the specific handover event. Once a handover pending record is paired to an existing anchor record, the handover pending record is converted to a routing record to route messages to the anchor record.
