Polycom RealPresence Trio 8800

Would like some more suggestions on this topic. Looking to move to a 3rd party hosted Skype PBX to replace our internal VoIP system, we run O365/Exchange E3 currently and use UM in the cloud for voicemail. So that all works, Just want a phone system to integrate and has proven AA and Call queues etc which Cloud doesn't really do well with/preview

Anyway, one vendor suggested the Real Presence for 3 of our 4 conference rooms that are larger. We have professional A/V setups in these rooms, meaning a dedicated computer as a source, people can bring the SF3/4 that most employees have and plug into the HDMI on the conf table inputs, touch control/professional A/V controllers to handle the video etc.

Then, we typically just use a regular conference phone to call into the Skype Conf service.

So I'm not sure how an SRS or Real Trio, besides the implementation of having it tied to a conference room calendar, which we already use that method as a sheduling tool for users already, and integrating the phone/tie it to those accounts, what features either of these devices would provide for use having Skype features/functions built into them that our Professional A/V, controllers multiple inputs and touch screen controls for these devices will provide?

Sorry, kind of long post there. But not sure what SRS/Real presence as it is being offered to us, will do that isn't already handled and proven, with a user group that knows how to use the current systems and methods would play into this type of conference room setup.

Seems like the Real presence with remote mics would just serve as an audio device using Skype as the PSTN still, just some simpler conference room integration/meeting kickoff/integration. But otherwise, our SF3/4s and dedicated computer as a source as well, or Apple TV for Mac users to stream video to the monitors, what they will do for us?

Thanks
