| Grandstream • GRP Series • Carrier-Grade GRP2604 3-Line Essential IP Phone • GRP2604 / GRP2604P An essential 3-line IP phone built for mass deployment with zero-touch provisioning — full HD audio on handset and speakerphone, 5-way conferencing, dual Gigabit ports with integrated PoE (GRP2604P), and centralized management through GDMS.
|  | |||||
| Built for Mass Deployment Zero-touch provisioning through GDMS gives service providers and enterprises a centralized interface to configure, provision, manage and monitor hundreds of phones — no desk-by-desk setup. TR-069 and AES-encrypted XML provisioning also supported. | Crystal-Clear HD Audio Full HD wideband audio on both handset and full-duplex speakerphone, backed by noise shield technology and AI noise reduction that filter out background noise — plus 5-way conferencing to bring the whole team into the call. | Carrier-Grade Security Enterprise-level protection with secure boot, dual firmware images and encrypted data storage, plus SHA-256 authentication, SRTP, TLS call encryption and 802.1X media access control. |
The Essential Desk Phone for High-Volume Deployments
| Part of Grandstream's carrier-grade GRP series, the GRP2604 packs the essentials that on-site and remote desktop workers actually use: 3 lines, 6 SIP accounts, and up to 3 call appearances, presented on a crisp 2.7 in (132×64) backlit LCD with dual-color LED line keys. Power users get room to work: 10 BLF keys for monitoring extensions, 4 XML-programmable context-sensitive soft keys, and 8 dedicated function keys. The RJ9 headset jack with EHS support connects Plantronics, Jabra, and Sennheiser wireless headsets without adapter boxes. The telephony feature set is complete for business use: call park and pickup, shared call appearance (SCA/BLA), a downloadable XML/LDAP phonebook of up to 2,000 contacts, an 800-record call log, hot-desking, and server redundancy with fail-over for uptime-critical installs. Two hardware versions cover every desk: the GRP2604 ships with a universal power supply, while the GRP2604P adds integrated 802.3af PoE for clean single-cable installs (power supply not included with the P version). |  |
Ready for Your Brand, Ready for Any Desk
 | A swappable faceplate lets service providers and enterprises brand every phone with their own logo — a simple detail that turns a commodity endpoint into part of your identity, ideal for hospitality, MSP fleets, and white-label voice services. The included base stand offers two viewing angles (39° and 45°), and the phone is wall-mountable for reception areas, warehouses, and break rooms (wall mount sold separately). Layer 2 (802.1Q/802.1P) and Layer 3 (ToS, DiffServ, MPLS) QoS keeps voice traffic prioritized on busy office networks. Multi-language support covers English, Spanish, French, German, Portuguese and many more — a practical advantage for bilingual workplaces. U.S. compliance includes FCC Part 15 Class B and FCC Part 68 HAC (hearing aid compatible), a common requirement in enterprise and public-sector purchasing. |
