Grandstream GRP2612P 4‑Line IP Phone | PoE, Colour LCD & 16 BLF Keys

Grandstream GRP2612P: Professional 4‑Line IP Phone with PoE, Colour LCD and GDMS

The Grandstream GRP2612P is a professional 4‑line carrier‑grade IP phone that offers an exceptional blend of features, performance, and ease of deployment. It is designed for users who need more line capacity, visual call management, and centralised control – ideal for receptionists, team leads, managers, and call‑intensive roles in small‑to‑medium businesses.

Vibrant Colour Display & Intuitive Interface

The phone features a 2.4‑inch TFT colour LCD (320×240) that provides crisp, easy‑to‑read call information, contact lists, and system menus. The backlit display ensures visibility in all lighting conditions. Four XML programmable context‑sensitive soft keys allow for customisation of frequently used functions, streamlining daily workflows.

4 Lines, 4 SIP Accounts & 16 BLF Keys

Supporting 4 SIP accounts and 4 multi‑purpose line keys, the GRP2612P handles medium to high call volumes with ease. The standout feature is its up to 16 digital BLF (Busy Lamp Field) / speed‑dial keys (virtual programmable keys), accessible via the colour display. These allow receptionists and managers to monitor the real‑time status (busy/idle/ringing) of other extensions and speed‑dial frequently contacted numbers – dramatically improving response times.

5‑Way Conferencing & HD Audio

The phone supports 5‑way audio conferencing directly from the handset, enabling team collaboration without external bridges. Noise Shield Technology actively filters out background noise (keyboard clicks, office chatter, air conditioning hum), ensuring that the person on the other end hears only your voice. HD wideband audio on the handset and full‑duplex speakerphone, combined with codecs G.722 and Opus , delivers crystal‑clear, natural conversations.

Swappable Faceplate for Branding

The GRP2612P features a swappable faceplate, allowing businesses to customise the device with their own logo or branding – perfect for hotels, co‑working spaces, and branded office environments.

Easy Deployment with PoE & GDMS

The GRP2612P includes integrated PoE (802.3af) , so a single Ethernet cable provides both power and network connectivity – simplifying installation and reducing cable clutter. For non‑PoE environments, a universal 5V DC power adapter is also available.

The phone is fully compatible with Grandstream Device Management System (GDMS) , a free cloud platform that enables zero‑touch provisioning, centralised configuration, real‑time monitoring, bulk firmware upgrades, and troubleshooting – for a single phone or thousands across multiple sites. It also supports automated provisioning via TR‑069 and encrypted XML configuration files.

Enterprise‑Grade Security & Reliability

The GRP series includes carrier‑grade security features:

• Secure boot – prevents unauthorised firmware

• Dual firmware images – fail‑safe upgrades

• Encrypted data storage – protects sensitive configuration

• TLS and SRTP encryption – secures signalling and voice media
