>                 Key: ASTERISK-22514
>                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-22514
>             Project: Asterisk
>          Issue Type: Bug
>          Components: Core/Stasis
>    Affects Versions: 12.0.0-alpha1
>            Reporter: David M. Lee
>
> h2. Steps to reproduce
> # Configure with ARI
> # Configure a bit of dialplan to answer a channel and send to Stasis()
> {code}
> exten => 7000,1,Noop()
>  same => n,Answer()
>  same => n,Stasis(hello)
>  same => n,Hangup()
> {code}
> # Connect ARI application 'hello'
> {code}
> wscat -c 'ws://localhost:8088/ari/events?api_key=ari:ari&app=hello'
> {code}
> # Dial extension 7000
> h2. Expected Results
> Call should happily sit there indefinitely.
> h2. Actual Results
> With some clients (Blink in my case) after about 30 seconds the call with end with an 'Audio Timeout'.
> h2. Notes
> Since silence generation is not necessarily a cheap operation (signed linear silence transcode is usually required), it should be configurable for the typical case where silence generation isn't actually needed (because there will only be brief silence; the application will play its own audio).
