Abstract
A method of operating a gateway is disclosed to manage communications between a switched circuit network and an internet protocol network using a gateway. The method includes receiving at the gateway, a service call requesting the service for routing to an application server on the internet protocol network. If the application server is available the service call is routed to the first application server and the gateway generates an entry in its database. The entry includes the service identifier and the first application server identifier. If the application server is not available to accept the service call and the service call is routed to the application server when it is not available, the method includes sending a control message to the calling party on the switched circuit network.
