Polycom Trio 8800 Video Freezing

[sliderjt]

Hi all,

I have deployed 5 Polycom Trio 8800 devices around the country and all but 1 are working correctly.

Issue: Video freezes after 2 seconds into a Skype for Business Online call. Sometimes the device will not start video straight away. The user has to click start video again.

Firmware: 5.4.5.9658 (was on 5.5.2.11338 but I downgraded it to try and fix the issue)

Other details: Audio works fine. QoS tags are set. Skype to Skype calling from a PC on the same network has no issues.

Network: 10mbit fibre. 2 users only, plently of bandwitdh available.  

What has been done already:

1. Downgraded the firmware
2. Reset all settings
3. Uploaded a known good working configuration
4. Power cycled the devices
5. Confirmed QoS is configured correctly

I have attached the logs if that helps.

Any help on this issue would be great.

Hello sliderjt,

welcome to the Polycom Community.

As you already stated the other 4 units work well but 1 unit does not. You could try and swap the physical unit to exclude a hardware issue but most of the time this would be a local issue.

The community's VoIP FAQ contains this post here:

This new FAQ post explains how to use the statistics with the Trio to check for dropped packets etc. so you can look in your network.

Try adding this into your Trio's CFG file:

<video video.decode.artifactTolerance="100"/>

Hello JessieBryan,

welcome to the Polycom Community.

Looking you and the Parameter up I can see you had raised 1-6188573472.

The is a new yet undocumented Parameter introduced in UC Software 5.5.2 and therefore may or not work for any older release as stated by the original poster.

Yes, I did open a ticket after we're unable to fix it ourselves. The parameter was given to me while using 5.4.5AC and I was informed the parameter has been around a little longer but was never documented. 

sliderjt, In terms of this forum post, you get what you pay for - so please don't be upset if the parameter doesn't fix it!
