Re: [Freeswitch-users] What is the difference between preAnswer and ring_ready?

Hi, Assuming an inbound call, I have trouble understanding what the supposed difference between the following two set of instructions is:

session.execute("ring_ready"); session.set("set", "ringback=/home/ring.wav");

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).

and

session.preAnswer(); session.streamFile("/home/ring.wav")

I think that will play the file as early media.
