+# IVR Java Sample #
+
+This is an ivr sample client.
+
+## Configuration ##
+
+The sample comes with a conf.yaml file located in the current directory  
+(IVR_Java). This config file must be modified based on your configuration.  
+Your certifcate must also be located in this directory.
+
+Here is the structure of the config file:
+
+**ip**: ip adress and port of your X2 server
+**certificate**: name of your certificate file if it is located in the
+     ivr_client directory.  If it is elsewhere, then the full path to your
+     certificate file.
+**username**: username to use to connect to the X2 server.
+**password**: password to use to connect to the X2 server.
+     the username and password must be configured on the X2 server.
+**applicationName**: application name configured on the X2 server.
+**dids**: The DIDs that will be used for this application.  THose DIDs  must be
+      added to the X2 server.
+**connectUsingServername**: if set to true, the server name and port will be used
+     to establish a connection to the X2 server.  If set to false the IP address
+     and port will be used to establish a connection.  This is because if
+     attempting to connect with the IP address and it is the serverName in the
+     certificate file, then connection may fail.
+
+## Building the sample ##
+
+If making changes to the sample code, the sample can be built by running the
+following command from the current directory:  
+  
+./gradlew build
+
+The resulting .jar file (IVR_Java-all.jar) will be placed in the current
+directory.
+
+## Running the sample ##
+
+The sample can be run in one of two ways:  
+
+1. From the current directory (IVR_Java):  
+   ./IVR.sh
+2. From the current directory (IVR_Java):
+   java -jar IVR_Java-all.jar
+
