Opus audio configuration paramaters

Can we get documentation on the opus audio paramaters which are supported on the VVX500/600. It'd be nice to know what the parameters do and their proper values.




Also, is Forward Error Correction (FEC) support for OPUS already builtin or coming in an update?

Re: Opus audio configuration paramaters

Hello @donileo,

welcome to the Polycom Community.

Both the community's Must Read First and the community's FAQ reference the basic minimum information a new or follow up post should contain.

This ensures the questions having to be asked are limited and any new or follow up post contains the right amount of details to ensure any voluntary participant within the community does not spend additional time chasing basic information.

As a reminder the basic information asked for:


    • Provide the exact Software Version of your Phone


    • Provide the Phone Model


    • Provide the Call Platform (aka openSIP, Skype for Business, Lync)


    • If applicable provide a backup of the phone in question


    • If possible provide a => Log <= and either attache them or use the => Code Tag <=. Consult the Troubleshooting Section found within the FAQ if applicable


    • If possible provide the MAC Address or Serial of the device


    • Provide details if the issue is a day 1 issue or only happened after an upgrade or any other relevant details


Whilst providing the answers to the above may not directly impact any possible answer the community can provide, it does enable Polycom to have an overview of the current software used in the field.

Please ensure you always check the FAQ's and/or utilize the community search before posting any new topics or follow up post’s.

Aug 09, 2016 Question:Why can Polycom not discuss future software Versions within the Community?

Explanation:Polycom, as a US based company, cannot share any future release dates or new features due the requirement of a non disclosure agreement / NDA prior to this.Via the medium of a community forum we are unable to do this.

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