NX device configuration
and portal access

The Call4tel management portal enables distributors and resellers to manage and view their devices from one centralized location. It collects all appliance information and details and links them with end users.

The portal is designed in such a way that it allows distributors to manage their resellers and end-users. From creating an account to resetting passwords and registering products, the portal caters for everything.

Resellers can manage their customers directly from their portal.

Supported Devices

Instructions for Distributors / Resellers:  

Distributors and resellers share the same screen and layout; however, resellers have access to fewer features. This manual focuses on showcasing the different features according to whether or not the portal user is a distributor or a reseller.
