Trio with CUCM

Hi, I do a lot of research before asking for help but I'm stuck.


there is very little information about getting the new Polycom Trio working with CUCM. All Admin Guide says is that it should work with limitation but doesn't say what those limitations are.


I was able to register the Trio + Visual to CUCM but I can only use it as a phone. I'd like to use it as a full blown video conference unit. 


any help will be appriciated.


I'm running CUCM 8.6 and the latest Trio Software. 


I'm able to make video calls to the RMX via Cisco video phones already on the network so I know the SIP trunk and profiles are set properly.


thanks again and any informatoin will be greatly appriciated.

Re: Trio with CUCM

Hello herrerajc,

welcome to the Polycom Community.

It is really bad practise to state you are using the latest software as this can be a misleading statement in the future as people will not know what the version at time of posting was.


It is therefore always useful to include the currently used UC Software version as issues experienced may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes.

The above is also stated in the "Read First: Welcome to the Polycom VoIP Forum"

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP UC Software Version or the BootROM Version of my Phone?
Resolution: Please check here


As stated above the release notes for UC Software 5.4.2 AA (at the time of the post latest software) list's on page 14 the Server interoperability including Cisco CUCM:


  • Cisco Unified Communications Manager 10.5 and 9.1

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
