How do you lock rinerg volume on a Yealink T57U phone.

Hi Joseph, do you mean ringer?

Joseph,

Our organization needed the same thing accomplished. We were able to utilize a custom config file.

This will likely require a custom configuration file for your environment's provisioning server. You can discuss with your account rep to explore options.

Thanks for helping, @Brett McVay!

@Joseph Varona, if you need help reaching out to your account rep, let me know.
