Two screens: the call on one, the team on the other

The large screen handles the active call, menus and phonebook, while the side screen stays dedicated to team keys. During a customer call you can see that your deputy is free and the finance manager is busy, and decide whether to bring one of them in or transfer. The ten fixed keys include dedicated conference and phonebook buttons.

Multiple SIP accounts for a busy manager

Register your direct line, the department line and an account on a branch PBX. Hot-desking lets any employee log in and load their own settings, useful in shared offices. The phonebook holds up to 2,000 contacts and the call log up to 2,000 records.

USB and Bluetooth for headsets

According to Grandstream's documentation, the USB port supports Grandstream GUV headsets and other USB headsets. Bluetooth pairs a wireless headset, and the RJ9 jack supports EHS for Plantronics models. Audio is HD wideband with G.722 and Opus, and Noise Shield technology keeps background noise down.

Central management, security and your logo

The phone provisions automatically through GDMS, TR-069 or AES-encrypted XML files. It boots with secure boot, keeps dual firmware images and encrypted storage, and supports TLS, SRTP and 802.1X. Swappable faceplates carry your company logo, and Arabic menus are available.
