GO HERE How to report Yealink V83 bug?

[Johann]

There is a bug on Yealink V83 firmware that breaks OpenVPN.
What is the best way to report this to Yealink?

I am running Yealink T23G and T42S phones connecting to my server via OpenVPN.
V83 has introduced an issue.

When on a call I have brief 2 seconds audio dropouts every 48 minutes.

This is what an excerpt from syslog on the phone whenever the audiodrop is happening:

Apparently there is a TSL soft reset happening.
This is only happening when live on a call, not when the phone is idle and causes the audio to drop on all phones I have tried it on. Never happens on V82.
