+Tutorial SIP Redirect
+================
+
+Scenario:
+---------
+
+- FreeSWITCH with minimal custom configuration. 
+
+ - Added following users (with configs in *etc/freeswitch/directory/default*): 1001-prepaid, 1002-postpaid, 1003-pseudoprepaid, 1004-rated, 1006-prepaid, 1007-prepaid.
+ - Have added inside default dialplan a redirect for the destinatin 1001 to the CGRateS SIPAgent that will populate the Contact header and add X-Identity header
+
+- **CGRateS** with following components:
+
+ - RALs to calculate the maxusage
+ - RouteS to get the rounting information
+ - ChargerS to change the destination for each route
+ - SIPAgent to comunicate with FreeSWITCH
+ - SessionS to comunicate with the agent
