In firmware version 83, Yealink introduced the feature 'Warning Display' Yealink IP phone support displaying a warning icon in the status bar, and warning information on the Status screen when the default password is used. It is used to remind users to change the default password as soon as possible.

When a Zero touch provisioned device is created on the Kwebbl panel, the system sends unique link to the Yealink redirection service. After factory reset the device goes to the Yealink service, receives the unique link to our system and then receives all the settings from us. Yealink keeps these links only for 14 days. This means if you make a factory reset to a device that is auto provisioned longer than two weeks, you need to edit the device in the panel to refresh the link. Editing t...

The green dots in the Devices tab indicate the device is registered at the DNS-SRV server while the yellow dots indicate the device is registered at the A-Record (Legacy) server. Both green and yellow dots show that the device is registered and should work properly. The main difference is the mechanism of ensuring registration in case of a server failure, with DNS-SRV the interruption is minimized while using the A-Record registration renewal could take up to 5 minutes (300 seconds), so DNS...

The majority of registration losses is caused by local network issues. To address the issue please first check the internet connection and firewall settings. In case the issue persists a trace is needed to determine the cause. Some devices (like Yealink) offer the opportunity to start a trace from the device itself. You can run this feature (insert link) and send us the trace outcome. If the device does not support this feature please open a ticket requesting a trace. We will provide you wi...

If you cannot add the device and an error message ‘MAC ID already in use’ is observed, this means the device’s mac address is already seized: - the device is already added in our system, although not used, - the device is registered at another company on the Kwebbl platform, - the device is registered on another platform than Kwebbl. In case we need to check on that, please raise a ticket stating the brand of the device (Yealink, Gigaset, Panasonic) alongside the MAC address o...

Adding devices to Zero touch provisioning means that when a device is created on the Company panel, the Kwebbl system sends special link to the Yealink/Gigaset/Panasonic service. After the required factory reset, the device connects to Yealink/Gigaset/Panasonic service, gets a special link to the Kwebbl system and receives all settings from our side. During this step we push the settings set on the panel in the 'Device' tab in 2 files: - one file containing basic settings, - one file con...

Provisioned Yealinks, Gigasets and Panasonic's use DNS-NAPTR/SRV to connect to the Kwebbl Platform. Some old(er) or non-standard DNS Servers do not support NAPTR or SRV requests and thus the phone is unable to register. To see if your phone is affected by this issue, check the following settings on the Account page via the phone’s Web interface: - Domain is set to notls.<domain>, eg notls.sip.kwebbl.net; - Port is set to 0; - Protocol is set to DNS-NAPTR; - Account shows registrati...
