When enabled, Zoom Phone monitors the network location of your registered desk phones and can block devices that connect from unauthorized networks. This is especially useful for preventing misuse of stolen or removed phones, since a blocked device can't register with Zoom Phone and therefore can't make or receive calls.

Note: The following device types are excluded from network location restrictions and are not affected by this feature:
