Clear MWI on Yealink with Voicemail Restful Phone App

Commercial Modules
1

I have Yealink T23Gs. I don’t need the MWI light on my Voicemail Restful Phone App button to indicate a new message.

How do I turn this feature off?

How do I clear the existing MWI on phones without having to listen to or delete voice messages?

2

Disable the MWI from the yealink phone web interface.

3

This is disabled on the phone’s web interface, but apparently doesn’t have effect on the Phone App MWI.

4

Change the mailbox from extension@default to extension@device.

5

I think the only way to do this is request a disable feature.
