Reliable SIP-Based Business Communication

The GRP2602LP is designed for organizations using SIP-based telephony systems. It can work with compatible IP-PBX platforms and hosted VoIP services, subject to service-provider requirements and correct SIP configuration.

Two SIP accounts and two lines support everyday calling workflows, while call transfer, hold, forwarding and waiting features help users manage incoming and outgoing business calls.

Integrated Power over Ethernet

With integrated IEEE 802.3af PoE, the GRP2602LP can receive power through a compatible PoE switch or injector. This reduces the need for a separate power adapter at every desk and can simplify structured cabling in larger deployments.

The GRP2602LP uses two switched 10/100Mbps Ethernet ports. When planning an installation, verify the switch’s PoE compatibility and available power budget, particularly when deploying multiple phones.

5-Way Audio Conferencing and HD Voice

The phone supports 5-way audio conferencing for routine team discussions and customer calls. Its full-duplex speakerphone and handset audio help users communicate clearly in common office environments.

Supported codecs on the GRP2602 family include G.711, G.722 wideband, G.729A/B, G.726, G.723, iLBC and Opus. Actual audio quality depends on codec negotiation, network conditions and the capabilities of the connected telephony service.

Centralized GDMS Management

Grandstream Device Management System (GDMS) supports centralized provisioning, configuration, monitoring and management of compatible Grandstream endpoints. This can reduce the time required to deploy and maintain phones across offices, departments and multiple locations.

The phone also supports a local web interface and provisioning methods documented for the GRP2602 family. Exact management capabilities depend on firmware and the selected deployment platform.

Headset Compatibility and User Controls

The GRP2602LP includes an RJ9 headset interface and supports Electronic Hook Switch (EHS) functionality with compatible Plantronics, Jabra and Sennheiser headset accessories. Dedicated keys for common functions such as headset, mute, transfer and speakerphone make everyday call handling more convenient.

Check headset compatibility and any required EHS cable before ordering accessories.

Security for Business Telephony

The GRP2602 family includes security capabilities such as secure boot, encrypted configuration files, TLS, SRTP and 802.1X support as documented by Grandstream. These features help protect device configuration, network access and supported voice communications.

For best results, keep firmware updated, use strong administrative credentials and configure the phone according to your organization’s network security policies.
