+Kamailio_ Integration Tutorials
+===============================
+
+In these tutorials we exemplify few cases of integration between Kamailio_ and CGRateS_. We start with common steps, installation and postinstall processes then we dive into particular configurations, depending on the case we run.

+Kamailio_ interaction via  *evapi* module
+=========================================
+
+Scenario
+--------
+
+ - Kamailio default configuration modified for **CGRateS** interaction. For script maintainability and simplicity we have separated CGRateS specific routes in *kamailio-cgrates.cfg* file which is included in main *kamailio.cfg* via include directive.
+
+ - Considering the following users (with configs hardcoded in the *kamailio.cfg* configuration script and loaded in htable): 1001-prepaid, 1002-postpaid, 1003-pseudoprepaid, 1004-rated, 1005-rated, 1006-prepaid, 1007-prepaid.
+
+- **CGRateS** with following components:
+
+ - CGR-SM started as translator between Kamailio_ and CGR-Rater for both authorization events as well as accounting ones.
+ - CGR-CDRS component processing raw CDRs from CGR-SM component and storing them inside CGR StorDB.
+ - CGR-CDRE exporting rated CDRs from CGR StorDB (export path: */tmp*).
+ - CGR-History component keeping the archive of the rates modifications (path browsable with git client at */tmp/cgr_history*).
+
+
+Starting Kamailio_ with custom configuration
+----------------------------------------------
+
+::
+
+ /usr/share/cgrates/tutorials/kamevapi/kamailio/etc/init.d/kamailio start
+
+To verify that Kamailio_ is running we run the console command:
+
+::
+
+ kamctl moni
+
+
+Starting **CGRateS** with custom configuration
+----------------------------------------------
+
+::
+
+ /usr/share/cgrates/tutorials/kamevapi/cgrates/etc/init.d/cgrates start
+
+Make sure that cgrates is running
+
+::
+
+ cgr-console status
+
+
+CDR processing
+--------------
+
+At the end of each call Kamailio_ will generate an CDR event via *evapi* and this will be directed towards the port configured inside *cgrates.json*. This event will reach inside **CGRateS** through the *SM* component (close to real-time). Once in-there it will be instantly rated and be ready for export. 
+
+
+**CGRateS** Usage
+-----------------
+
+Since it is common to most of the tutorials, the example for **CGRateS** usage is provided in a separate page `here <http://cgrates.readthedocs.org/en/latest/tut_cgrates_usage.html>`_
