Grandstream provisioning guides
How to provision Grandstream IP phones for calling with Telzio.
Telzio's zero-touch auto-provisioning enables you to remotely configure Grandstream IP phones with your Telzio service. However, if auto-provisioning is not supported on your device, you can manually provision them following our guides.
Find the setup guide for the phone series of your device in the left menu.
