Ring_ready sends a SIP "ringing" message and will use your device's default
ringback sound - at least, that has been my experience. I should remember the
message number in the SIP protocol, but I don't (the SIP experts here will
undoubtedly have the details at the ready).
I think that will play the file as early media.
