V83 and openvpn problem

[avayax]

I am running Yealink T23G and T42S phones connecting to my server via OpenVPN.
Everything works well with V82 but 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.

Confirming that this V83 firmware is a problem on a T41P phone, too.

Upgrade to V83, VPN does not connect.

Downgrade to V82, VPN works again.

SAME PROBLEM all the way through latest .50 firmware.

Downgrade from V83 .50 firmware back to V82, and VPN works again.

YEALINK, YOU NEED TO FIX THIS IMMEDIATELY. THIS IS A HUGE FAILURE AND IS IMPACTING CLIENT PHONES.

We are having the same problem. I have tested it on T41 and T42. Any update on this would be apreciated.

Try upgrading to V84, I have successfully tested OpenVPN on a T41S running V84 with no drops or loss of connectivity for 3 days so pretty sure the issue is fixed.

Almost a year later and this is STILL an issue. Trying to get a remote phone to work with VPN for a client.

YEALINK, why have you not fixed this for customers?

This is for a T41P, NOT a T41S, so there is no newer firmware to fix this issue.

What gives?

Why have you not addressed this problem?

Why not just roll back to V82 that works properly? While not officially dropped T41P has basically been directly replaced by T41S so chances of getting any further updates for it are pretty slim unless you have thousands deployed and are trying to make a business case to Yealink...

[caldwell]

Or ... Yealink could take support of their products seriously.

Yeah, that's an idea.

This has been a longstanding issue with Yealink and bugs in my experience, and VPN is just one of the issues I've encountered which just never got fixed.

Really, how long would it take them to FIX this problem and roll out a new firmware?

Is here Any Update? - i Still try to find a working Solution with OpenVPN und V83 firmware.. at this moment i stuck on a Working V82 Setup :/

To my knowledge the solution provided by Yealink was to upgrade to V84 firmware. If you're on a device that did not get V84 firmware, and latest V83 still has the problem then V82 is your only option.

Out of curiosity what features from V83 do you want that you're not getting in the last V82? If I recall the change from 82 to 83 was not that big and 83 didn't last long before they bumped everything to 84 where new models/features began to appear again...

The problem with this is that if a customer is using 3CX or other supported VOIP systems, they require a customer's phones to be on the "latest SUPPORTED firmware."

People can't get support from their PBX vendor if they run v82.

YEALINK, hey Yealink! Are you listening?

You need to fix this issue and provide an updated firmware for these older phones. Even if all you do is fix THIS issue, you need to support your customers.

It gives your company a black eye and gives your resellers a bad name when you leave your phones in a BROKEN state.
