My understanding is that the file is looped in early media mode for as long as the far leg of the call is in a provisional state.

So when I read the explaination of SEMS early_announce it says "(pre- call) announcement using early media (183), optionally continues the call in B2BUA mode"

Does this mean that when the caller calls the callee, instead of hearing the ringing sound while you are waiting for the callee to pick up the caller will hear whatever wav file you want them to hear? Is that what early_announce does?

If so what happens if the wav file isn't done playing but the callee picks up? Does the wav file get cut off and you are able to talk to the callee?
