[asterisk-dev] Audio to/from Asterisk

[George Joseph]

Hey Guys,

I was on vacation when this thread happened but I'm also working on this
now.  The implementation uses the existing ARI channel and bridge recording
endpoints ands add the ability to specify a URI in the form of
(udp|tcp|tls)://hostname:port to stream the media.  This makes use of the
existing chan_bridge_media driver and only requires a scheme handler
similar to Seán's res_audiosocket.   This implementation is more targeted
to real-time speech recognition/transcription/captioning and is therefore
one way (outbound).  A future enhancement is planned that would send each
channel in a bridge as a separate audio channel in a multi-channel
container.

I'm not suggesting that this should replace Seán's audiosocket stuff but I
did want to let you know what was in the pipeline.
