work here. It deals with the wholesale call traffic between and over exchanges
as well as Local Access and Transport Areas. That is why the Class 4 softswitch
solution is called the Wholesale softswitch solution; whereas the Class 5
softswitch deals with the local users. It route calls in relatively small areas
