How to install Grandstream GRP2624 IP Phone

Installing the GRP2624 is designed to be straightforward, whether you’re configuring a single unit or rolling out thousands. Start by choosing your power and network approach, then configure and test the device to ensure optimal performance across your organization.

1) Prepare the network and power: Connect the GRP2624 to your local network using the Ethernet port for a wired setup, or leverage the built-in Wi‑Fi if you prefer a wireless connection. If you’re using PoE (Power over Ethernet), plug the device into a PoE-enabled switch to power and network the phone simultaneously. If PoE is not available, use the supplied AC power adapter as an alternative.

2) Find the device’s IP address: After powering up, locate the IP address assigned to the phone. This can be found on the phone’s display or via your DHCP server depending on your network setup. If your network supports DHCP, the device will typically receive an address automatically.

3) Access the Web UI or provisioning server: Open a web browser and enter the device’s IP address to access the web-based user interface. If your organization uses zero-touch provisioning, the phone will automatically fetch its configuration from the centralized provisioning server once registered. If manual configuration is preferred, log in with the default admin credentials and begin configuring accounts, network settings, and preferences.

4) Configure accounts and features: Set up SIP accounts, call settings, directory preferences, and any enterprise-specific features such as LDAP integration, VLAN tagging, or QoS rules. When deploying in bulk, apply site-level templates to ensure a consistent user experience across all devices, reducing individual configuration time and avoiding misconfigurations.

5) Update firmware and test: Check for the latest firmware version and apply updates if available. Perform a basic call test, verify headset or speakerphone functionality, and confirm the device can join conferences smoothly. If you enable Wi‑Fi, complete a quick network scan to select the preferred SSID and verify signal strength in the intended workspace.

6) Document and train end users: Provide end users with simple usage guides, including how to access voicemail, manage contacts, mute/unmute, and participate in multi-party calls. Consider creating a quick-start sheet for agents or front-desk staff to minimize first-day confusion and maximize productive use from the start.
