Local Media Optimization with Trio 8800.

Question: Is Local Media Optimization not supported with Trio 8800 running firmware 5.9.5?


We have recently updated our 4 yr old Trio 8800 to 5.9.5 and trying to get it to work with Teams.


We are facing an issue with Call transfer to external numbers through local SBC. In SBC logs we see a Media error and then transfer fails. After some troubleshooting we got the transfer to work after removing the subnet for this Trio from list of subnets for Local media optimization from Teams tenant.

Hello @Ashish Mishra ,

Welcome back to the Poly community.

Some or a couple of your old post(s) or reply(s) to them => here <= are still open/pending as you have not marked these as "Accept as a solution" or at least provide some form of feedback or answer.

If they are in this state nobody finding them via a community search will know if an answer or advice provided was useful and has maybe helped you.

Could you therefore kindly go over them and mark or answer as appropriate?

If they are marked as "Accept as a solution" other users can find these easier and it helps them to utilize the community more efficiently. Please do not simply mark them without any type of feedback.


To answer your new question I do not believe we do as I could not find any reference to this in my research.

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

Best Regards

Steffen Baier

Do newer Poly conference devices like C60 support Local Media Optimization?
