Group Series Content Dropping, how prevalent is EN-89389?

23 GS Endpoints (310/500/700). Updated early sept I believe. Heavy usage started around Sept 20 (updwards of 25+ calls a day with 3-5 endpoints in each call - we have upwards of 40 HDX that have no issues).


All using RMX 1800 (6.4). DMA (9.x, whatever is newest). Early Oct started getting calls of dropped content. This is a teach enviroment, so generally one endpoint engages content and runs it a full hour.


We started with troubleshooting in-room wiring, reseating HDMI connections, etc. We use a ton of HDBT to extend the content source to the Polycom endpoint, to pump the TV1/TV2 outputs to displays, etc. This has not been a problem for all the years we have been doing this.


Saw the release notes for on Oct 1 and EN89389 addresses what, appears to be, our issue. On 10/4/18 all GS units and associated touch panels were updated. From 10-5 through today (10/11) the reports have generally been good. The constant dropping of Content has subsided for most situations. However, we have a few instances where it is still happening. Seems random and not tied to any particular GS. Its way less frequent than it was before the udpate, but still a problem. Before the previous update, this wasn't really an issue.


Do we have any insight on what EN89389 is solving? Is it a potential issue still?


We have conferences where all the endpoints are HDX and this is a non-issue. It seems to be tied to GS units sending content.

EN-89389 dealt with a GroupSeries issue when using the internal bridge and accepting a 2nd call
