What to do if Grandstream Networks IP Phone cannot register after provisioning?
- JJohn PrattJul 27, 2025
If your Grandstream Networks IP Phone fails to register after provisioning, first ensure the registered MAC address and provisioning server details are correct. Then, examine your network environment, focusing on router UPnP and SIP-NAT settings. If filtering is enabled on your routers or firewalls, add a rule for our provisioning/login server. If issues persist, contact customer support, providing your unique number, MAC address, and device model.
