Full Version: Web Gui Locked Up

We have over 300 T21, T23G & T29G mixed all over our network. The problem we are facing that is at times the web gui just locks up. We have to bound the port (all poe) to get the phone to reboot before we can access via the web gui. We have factory reset on many of these phone and let auto provisioning configure the phones upon reboot but a few weeks/months later, we are agaom unable to access the phone via the web gui. Very frustrating, any advice Yealink?

Hi,

Please make sure that the GUI's of the phone are not accessible via the internet, because after too many invalid login attempts, the GUI will be blocked for an indefinite period of time.

Hope this will help.

They are only accessible inside our network, there is no traffic from the outside that are able to attempt to login.
