Most united communication could be carried out through various networks. With softswitch, the network more andal and economical without sacrificing the other network available.

Convergence between the network of the circuit (circuit networks) and the network of the package Cellular (packet network) was the evolution of multifunctional network technology in the future.
Eventually, the user of the telephone Cellular will communicate with many lines starting from when telephoning the house, the internet telephone in PC, telephoned the office, or conversely, with not only involved the voice, but also the data.

His process need not replace all the network of the available circuit, the migration cost of the cheap network, and in stages did upgraded headed the network of the package.
One of his methods was with technology softswitch.
This implement could connect between the network of the circuit and the network of the package, including inside was the network of the telephone continue to (PSTN), the based internet IP, the TV cable but also the network Cellular available uptil now.
