I'm getting the exact same issue as bluisana is reporting - 188.8.131.527 firmware and using the .amsx exchange integration URL
How is that case progressing - any detail you can share if it's configuration / bug / network etc?
I also am having few others issues with dialling from the Trio to any S4B O365 contact however incoming voice/video calls works from any user.
Plus the MeetNow/Scheduled S4B meetings don't work either although calendar integration works (receives meeting and can lookup contacts etc) couple of things i need to work through although i think that particular one might relate to this reported issue
Have been reading these forums (and Jeff's blog - its great) for similar issues prior to lodging case with Polycom support.
