Re: [asterisk-users] Help needed with ARI RTP externalMedia bridging please
You're a genius, sir! I don't know how I missed the part about ports, but
anyway...
Looks for "channelvars": {
"UNICASTRTP_LOCAL_PORT": "*14880*",
and then
vlc -vvv https://media-ssl.musicradio.com/LBCUK --sout
'#transcode{vcodec=none,acodec=*a*
law,channels=1,samplerate=8000}:rtp{dst=127.0.0.1,port=14880}'
Then the rest as before...
The other change I made was from ulaw to alaw, as ulaw sounded horribly
scratchy, particularly with "s" sounds. alaw was much better.
At last no more dynamic rewriting of moh files and then reloading moh etc
etc!
Thanks again.

You're sending media from Asterisk to VLC, not the other way around,
currently. You need to examine the result from the call to
channels/externalMedia, this will include the RTP port that Asterisk is
listening for media on. You then need to pass this to vlc somehow (I'm not
familar with the VLC options) and have it send RTP to that port.

[asterisk-users] Help needed with ARI RTP externalMedia bridging please
Very simply, I want to pipe some external audio into a channel (bridge)
using the externalMedia channel option.
Running Asterisk 18 on ubuntu, here's what I did to try and test things out:
open a console tab
vlc -vvv https://media-ssl.musicradio.com/LBCUK --sout
'#transcode{vcodec=none,acodec=ulaw,channels=1,samplerate=8000}:rtp{dst=127.0.0.1,port=5005}'
open another console tab
wscat -c
"ws://localhost:8088/ari/events?api_key=asterisk:asterisk=playback-example"
open another console tab
curl -v -u asterisk:asterisk -X POST "
http://localhost:8088/ari/channels/externalMedia?external_host=127.0.0.1:5005=musicChannel=ulaw=playback-example
"
curl -v -u asterisk:asterisk -X POST "
http://localhost:8088/ari/bridges/musicBridge?type=mixing;
then dial in from a phone
curl -v -u asterisk:asterisk -X GET "http://localhost:8088/ari/channels;
and note the new call channel ID
curl -v -u asterisk:asterisk -X POST "
http://localhost:8088/ari/bridges/musicBridge/addChannel?channel=,musicChannel"
... and there is silence when I expected either music or at least some kind
of noise.
Is it something I'm doing wrong with the channel mixing, or with the
transcoding with vlc? Been battling this all day and could really use a
second pair of eyes on this.
Thanks.
(PS - of course, I would use the node SDK for live stuff, and not
"asterisk:asterisk" as username/password!)
Here's the VLC output - does "PCMU/8000 on port 5005 RTP/AVP 0" look
reasonable?
