I am trying to implement something with JTAPI that it functions like an
IVR,I need to play something when a incoming call arrive.

To do that I have done this:

TerminalConnection tconn = null;
MediaTerminalConnection mtc = null;
if (callEv instanceof TermConnCreatedEv) {
tconn = ((TermConnCreatedEv)callEv).getTerminalConnection();
mtc = (MediaTerminalConnection)tconn;
try {
mtc.usePlayURL(new URL("file:/welcome.au"));
} catch (Exception excp) {
excp.printStackTrace();
}
}
but this code cause an exception that says com.cisco.jtapi.MethodNotSupportedExceptionImpl: Unimplemented

I look at the "Cisco JTAPI Developer Guide" documentation in the Appendix showing the MediaTerminalConnection.usePlayURL method is not supported.

How can I achieve this function? thanks.

Thanks!
