Hi, as the subject says, one of my phones (Yealink T41P) illuminates about every 20 minutes.
There is no message or any indication on screen of what is causing it. I have switched from another PBX system (3cx) which I used the same phone, but it did not do this, so I suspect it must be to do with the provisioning? It is driving me mad, does anyone have any suggestions how to track the issue, or what the issue is?
