[Iaxclient-devel] Audio Feature Questions

[Steven S. <ss...@so...>]

Has anybody experimented with directing audio from a file (i.e. a wave file)
over the IAX connection from the client end?  How about directing incoming
audio _to_ a file?  I think Steve K had some file code but I couldn't figure
out how it worked.  I would like to be able to implement the following three
features:

1.  Record both the input stream and output stream to a file (for call
recording purposes).  This would be similar to the monitor function
available from the Manager interface (and/or CLI).  I would guess that at
some point in the input and output process it would be feasible to direct a
copy of the data to a file.  It would be great to be able to put a "record
locally" feature into the phone allowing users to click to record/stop
recording.

2.  I would like people to play file data over the line.  This could be used
to play custom answering messages, and it could also be used to create a
very cool off-board IVR functionality.  Think about custom, client-side
scripting of play/record over IAX?

3.  Can IAX endpoints receive DTMF (or the equivalent thereof) digits?

I think you can see where I am going.  It would be an extremely powerful
extension to the library to be able to create automated telephony
applications off-board of the Asterisk.  It also seems like cool
functionality to build into advanced soft-phones.

I realize that most of you want to get the current library stable before we
go hacking further functionality into it.  I respect that.  If you think I
should hold off (or at least not tap the group's collective power) please
let me know.

Thanks,

Steve S.
