I’m going to assume phone muting is done at a device-level, and Asterisk does not process, handle, or care about muting events? If not - can I know more about that somehow?
Anyway - we are using Mitel 5224 phones here, and many of them - the mute buttons totally dont work at all. I imagine its something to do with firmware updates. But in case someone here has delt with this before, I was wondering if I can get some advise. Thanks.
