Description
The Grandstream GRP2602LG is a 2-line Essential Lite SIP desk phone with Gigabit Ethernet and PoE for our customers who want HD audio and four SIP accounts on a Gigabit desk drop. It supports 4 SIP accounts on 2 lines, 5-way audio conferencing, a backlit 2.41-inch LCD, Noise Shield with AI noise reduction, dual 10/100/1000 Mbps Ethernet ports with IEEE 802.3af PoE, HD handset and speakerphone audio, a swappable faceplate, an included universal power supply, and GDMS cloud management.
Choose the GRP2602LG when the desk needs Gigabit LAN and PC pass-through with PoE. If Fast Ethernet PoE is enough and you prefer a lighter package without a PSU in the box, use the GRP2602LP.
The Telecom Spot Take
Best for IT and facilities teams standardizing on Gigabit PoE to the desk while keeping an Essential Lite form factor. The LG pairs Gigabit dual switched ports and a Gigabit PC port with HD audio, four SIP accounts, and a swappable faceplate, and it still ships with a universal PSU for non-PoE fallback. It is not ideal when you only need 10/100 PoE and want the lighter LP package without a wall adapter.
