Uploading a custom config file with Advanced Provisioner
Before you begin
Section titled “Before you begin”- We cannot help with config file specifics. You will need to consult your manufacturer or distributor directly.
- Test without your custom config first. If you hit a problem, reproduce it on a device with no custom config before filing a support ticket. It makes troubleshooting much smoother.
- Supported devices are limited. Advanced Provisioner currently supports custom configuration files for Yealink (firmware v81+) and Polycom only. Other models are not supported, and we have no ETA for adding them.
