File Size is 0 after streaming channel

[abdulgig]

Hi there @sboily @pc-m

I have tried this with Asterisk 17. The module is loaded ,

*CLI> module load res_ari_stream.so
Loaded res_ari_stream.so
  == WebSocket registered sub-protocol 'stream-channel'
 Loaded res_ari_stream.so => (Asterisk Websocket Channel Stream Module)

I pass the channel to the script and I see it starts to capture the audio,

python3 get.py 1626527094.40

WebSocket connection from '127.0.0.1:40548' for protocol 'stream-channel' accepted using version '13'
NOTICE[9548]: res_ari_stream.c:238 websocket_cb: channel 1626527094.40 : new call (interface id = 0x1)

  == WebSocket connection from '127.0.0.1:40548' closed

However, I don't seem to get anything in the wav file. The size is 0.

fpbx:/usr/src/wazo-hackathon-asterisk-stream-module/contribs# du -hs *

0       out.wav

What could be wrong ?

Even with asterisk 18, same issue ! I thought version 17 was notorious for issues with streaming

Hello, I'm using the plugin without issue. I'm not available for the two next weeks, but I'll check documentation if we forgot something. Is it your python script?

[sboily]

Does the channel is answered?

[abdulgig]

@sboily , thanks for following up. Yes, the channel is answered

It is the python script from this repo under the contrib directory, so not mine

Here is how I am using it,

I make the call, get the channel ID of the call and then run the script by passing the channelID. I can see the output on my asterisk CLI which I shared above also.

It could be,

• It doesn't seem to pick media from the call
• Can be an issue with script itself
• Asterisk version, what version of Asterisk Re you using ?

Best Regards,

By the way, I also verified if there was any rtp traffic between both the end points. It is there !

Do you have a working config? Ast Version / script
