Your Grandstream phone may not be connecting to the network due to issues like incorrect network settings, faulty cables, or problems with the router or switch. Check that the Ethernet cable is securely connected, the network settings (such as IP address and VLAN) are correct, and the network equipment is functioning properly. Restarting the phone and network devices can also help resolve connectivity issues.
