Hi @Miguel_Angel_Herrera ---- Thanks for the clarification!
Moving forward can you please also provide a brief but accurate description of your current setup using this link as a guide.
Additionally, I am certain our tech team is going to want to have the firmware version that the POLY is currently running, and on top of that, it sounds like the techs over at chord were aware of an issue that got fixed (as per David’s post above). Have you reached out to their team yet to confirm which firmware release contained said fix? I re-read through their release notes and I am not seeing anything referencing the “increased buffer window”.
