Abstract
A method for a user of telecommunication services to dynamically interchange routing paths between a carrier network circuit and the Internet for connecting to a destination. A user code is allocated which marks a connection request as requesting switching/routing via an IP network. When the code is detected by a carrier switch, the call connections are routed through the IP network. The user is provided with the option of terminating the IP network connection and selecting carrier network connection without call interruption.
