ABSTRACT:
An access device enables dynamic migration of telecommunications subscribers between multiple transport networks and call services providers. The access device stores access patterns that associate a subscriber with a call server and define trigger events. The access device monitors the trigger events. The access device associates the subscriber with a different call server in accordance with the trigger events and the access patterns. The trigger events can be dynamic or static, can be on a line-by-line or call-by-call basis, and can be selected by a user or implemented by an operator. In this manner, the access device allows graceful migration of voice services from a legacy network to a next-generation packet network with lower capital and ownership costs.
