Product information

Description

The Grandstream Networks GRP2603 is a carrier-grade IP phone with a compact black design, three programmable lines and a 2.48" LCD display. Designed for business environments, the GRP2603 supports standard SIP-based VoIP protocols and Fast Ethernet (10/100 Mbit/s). It offers easy deployment with zero-touch provisioning and flexible power options including PoE on models that support it, making it suitable for managed multi-phone installations.

Advantages

The GRP2603 provides full HD audio on both handset and speaker to improve voice clarity during calls. It supports five-way voice conferencing for small team meetings and includes EHS compatibility with Plantronics, Jabra and Sennheiser headsets.

How to use

Connect the GRP2603 to your network using the Ethernet port and either power it via a compatible PoE switch or the appropriate AC adapter. Register the device to your SIP server or PBX following the zero-touch provisioning process provided by your administrator or service provider.
