		enableClient, nil, // for Client setup
	))

	for i := range availableSessions {
		func(ss *sip.Session) {
			// send to client
			if _, err := ss.Write([]byte("Hello! by server..\n")); err != nil {
				panic(err)
			}

			// recieve from client

	enableClient := true
	raddrs := []string{"localhost:5060"}
	availableSessions := sip.GetAvailableSessions(sip.NewConfig(
		enableServer, "", 0, // for Server setup
		enableClient, raddrs, // for Client setup
	))

	for i := range availableSessions {
		func(ss *sip.Session) {
			// send to server
			if _, err := ss.Write([]byte("Hey! by client!\n")); err != nil {
