ABSTRACT:
A method and apparatus providing improved service in IP networks requiring switch circuit connections by allowing many local systems to establish a switched circuit connection to a remote system without using equal cost routing. The invention detects when a system is over-subscribed (no circuits available for dial-out), congested (lacking other resources to provide dial-out), or more band-width is demanded, and scales to the demand by forcing dial-out from an alternative system. Existence of the new connection is made available to existing systems by updates to system routing tables. The scaling capability is also used to address incoming calls that require a callback from the most appropriate system.
