Zanzibar Open IVR

Hi Every one!. I followed the zabibar installation guide and successfully run the asteriskconnector.sh, rserver.sh,transmitter.sh,receiver.sh. From my x-lite i called the number and the sample dialplan given in the guide is executing. But the problem is neither i did'n hear any demo voices nor there is a single debug messages in any of the following, asteriskconnector.sh,rserver.sh,transmitter.sh,receiver.sh. Can any one suggest me how to get demo working. Thanks in Advance.
