Cisco endpoints registered to Pexip and running RoomOS 26.9 or 26.10 failed to receive incoming presentations during Teams CVI and Google Meet Gateway calls, while sending presentations continued to work. The root cause was identified as a change in how Cisco handles the presentation channel in the new RoomOS versions, prompting Pexip to roll back affected systems to 26.8 as a workaround. A fix was deployed during off-hours to minimize disruption and the incident was fully resolved within 20 hours.

This incident has been resolved.
A fix has been implemented and we are monitoring the results.
We have identified the issue with the new RoomOS version and have started rolling out a fix. Minor disruption is possible during the rollout, and a small number of calls may be affected. For that reason, the rollout will be carried out outside of business hours in each region.
We have identified a change related to how Cisco keeps the presentation channel alive, and are planning an update to adapt to the changes.
Cisco endpoints that are:
Registered to the Pexip service AND have been updated to 26.9 or 26.10
May fail to receive Presentation from the far end in calls via Teams CVI or Google Meet Gateway services.
Sending presentation is reported to work, and also unblocks the incoming presentation.
We recommend you do not update Cisco systems to 26.9 or 26.10 while we investigate.
Please roll any affected systems back to 26.8 while we establish the cause.
