Play file before answering


I am having dahdi channel running on ss7 configurations.

I now need to play a file before the call gets answered? How can I do this?


core show application playback

You will normally need to be considered a network operator by your upstream network operator, for early media to be acceptable, because early media isn’t normally billable, so could be abused by end users.

You may also need Progress(); I’m not sure if that is just for SIP passed through early media.
