How to use

Connect the phone to the network using the Gigabit LAN port and, if available, power it via PoE to avoid a separate power adapter. Configure accounts through the web GUI, provisioning server or use zero-configuration with a Grandstream UCM PBX for automatic setup. Program BLF keys and soft keys via the phone interface or web portal, pair a compatible Plantronics headset using the EHS feature, and verify audio and network settings before regular operation.

For deployments, use the integrated provisioning options (UCM zero-config, encrypted XML or TR-069) to streamline mass installation. Use PoE-enabled switches to reduce cabling and enable reliable power, and keep firmware up to date to maintain security (SRTP/TLS) and feature compatibility.
