A 3-line essential IP phone with 6 SIP accounts, a 2.7 inch backlit display, Gigabit Ethernet ports and GDMS management, designed for mass deployment.
The GRP2604(P) is a 3-line essential IP phone built for mass deployment and easy management. It supports 6 SIP accounts with up to 3 call appearances, a 2.7 inch backlit graphical display, and dual switched Gigabit Ethernet ports. The GRP2604P model adds integrated PoE, so it can be powered over its network connection, while the plain GRP2604 is the non-PoE variant in the same listing. A full-duplex speakerphone with HD audio, noise shield technology with AI noise reduction, and headset EHS support for Plantronics, Jabra and Sennheiser headsets cover everyday desk calling, and Grandstream's Device Management System (GDMS) gives a centralised interface to configure, provision, manage and monitor the phone. A swappable faceplate allows easy logo customisation, and enterprise-level protection includes secure boot, dual firmware images and encrypted data storage. Request a quote at AccessStore.lk.

They are the same 3-line phone in one listing, but integrated PoE is stated for the GRP2604P only. If you need the phone powered over its network cable, choose the GRP2604P variant.
It supports 3 lines and 6 SIP accounts, with up to 3 call appearances.
Yes, it is supported by Grandstream's Device Management System (GDMS), which provides a centralised interface to configure, provision, manage and monitor Grandstream devices.
Yes, it supports Electronic Hook Switch (EHS) for Plantronics, Jabra and Sennheiser headsets, and it has a full-duplex speakerphone with HD audio.
Grandstream's own page gives two figures and they do not agree: the feature bullets state 5-way audio conferencing, while the comparison table states a 3-way audio conference. Treat the conferencing count as unconfirmed until Grandstream clarifies it, rather than relying on either figure alone.
