I tried this yesterday, so your question got to me before I forget it :-) http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_pre_answer Pre-answer sends a SIP status code 183 and apparently opens up early media so that they can hear whatever tone stream you see fit to play to them. I also copied the example from the dialplan and padded some sleep time on either side of it to provide a cushion. I abandoned my effort at injecting a short 2600 Hz "wink" because it was too loud and hurt the ear. Perhaps an amplitude parameter might be in order for tone_stream? HTH Bote

Hello all,
I thought that just setting <action application="playback" data="tone_stream://%(400,200,400,450);%(400,2200,400,450)"/> or something similar would make freeswicth giving a ringtone when it opens a SIP-connection.
Alas, it doesn't.
I freely admit that I feel lost in all the documents available; so a "RTFM" is an completely acceptable answer; as long as you point me to the correct place.
Thank you.
