You cannot send any information down the line with out first providing answer supervision. It probably also won't work because in an SS7 network (like the PSTN) the bearer channel isn't built until the receiving side answers. So, without an answer your playback doesn't go anywhere. You should however be able to send the correct error message back to the caller via PRI signaling. -Matt -- Matthew S. Crocker Vice President Crocker Communications, Inc.
