Description
The GRP2604P belongs to Grandstream's GRP series of essential IP phones, designed for mass deployment and easy management. This model handles 3 lines, 6 SIP accounts and up to 3 call appearances, and starts 5-way audio conferences. Its full-duplex HD speakerphone is backed by Noise Shield technology and AI noise reduction that minimize background noise. It carries two switched auto-sensing Gigabit Ethernet ports with integrated PoE, which removes the need for a power adapter on a PoE switch, and supports Plantronics, Jabra and Sennheiser EHS headsets. Grandstream's GDMS platform centralizes configuration, provisioning, monitoring and management of the fleet. Enterprise-level protection relies on secure boot, dual firmware images and encrypted data storage, and the swappable faceplate makes it easy to add the company logo.

Use and tips
The GRP2604P suits businesses and service providers that equip many desks with a sober phone that still handles several accounts: standard workstations, small teams, multiple sites. Each phone registers in GDMS and fetches its configuration on its own, which cuts installation time. On a PoE switch, no power adapter is needed, and the two Gigabit ports let you chain the computer behind the phone. For wall mounting, add the GRP_WM_L kit. For a two-line Wi-Fi phone, see the GRP2601W.
