There are two methods by which IP Phones are maintained up to date with latest provisioning changes and the current firmware version – either via Resync through the Zoom Web Portal or via Auto Polling through the IP Phone itself.
By using the Zoom Web Portal, the Phone Administrator can initiate the Resync process. In this article, we explain in detail how to use this method. With the Resync method, device provisioning and firmware can be applied immediately to the devices. In this way, it would be recommended to target specific phones or to perform the action in batches in the evening hours in order to avoid having any impact on the user of the phone. It is important to view Resync as an administrative tool for troubleshooting or configuring devices that have an immediate need for an update, rather than a feature that needs to be used for configuring devices.
As a result of the Auto Polling/Pulling mechanism, the device will check for updates on predefined dates/times defined by the manufacturer of the device, and will automatically respond to these updates as soon as the device detects them. As soon as a new configuration is added or if there is a new firmware version to be applied, the IP Phone will check with the Zoom Phone service for any updates. When any changes are made, it is possible that changes will be applied to the IP Phone. As a result of this method, we are able to ensure that all IP phones, including their software updates, are updated regularly to ensure they stay up to date with the latest settings. I would like to point out that the polling is usually performed at a time when the devices are not being used (for example – holidays / after midnight), subject to change by the device manufacturer. It is the default polling/pulling method for Zoom Phone service that is used by default.
