Referencing the following,
Spark 2.6.3+OpenFire 3.7.1+Asterisk (bad voice to sip)
It looks like there has been a problem with spark and poor audio for sometime. Possibly from making the switch to FMJ. Since I'm not a dev or coder, would anyone be willing to take a look at this? I know the spark dev has been sparse. Perhaps a simple fix for someone that knows what they are doing would be to use libjitsi? libjitsi | Jitsi
Thanks
