Grandstream GXP1610The phone that would not die.

Why the GXP1610 is on the catalog.

The GXP1610 has been in Grandstream's catalog longer than some of our customers have been in business. Released in 2014, refreshed in 2018, still shipping in 2026. It is the cheapest real SIP phone Grandstream makes — and despite a decade of newer GRP-series phones, it still gets ordered every week because of two simple facts: it costs under $50, and it just works.

It is a wired-only, no-Wi-Fi, no-PoE, two-line phone with a handset and a tiny 132×48 backlit LCD. The screen shows you who is calling, the keys ring you through to the call, the handset gives you HD voice via G.722. That is the whole product. If you need anything more — color screen, PoE, Bluetooth, BLF keys, USB — you have moved out of GXP1610 territory.

Where it still makes sense in 2026: hotel guest rooms (the phone never moves, the user never needs to configure anything, the handset never gets unplugged), break rooms, warehouse counters, satellite kiosks, anywhere you would otherwise buy a $20 retail brand IP phone but you want real SIP firmware and TR-069 provisioning. Also: replacement units for existing GXP1610 deployments — Grandstream still supports the same provisioning XML format from 2014, so you can drop a new one into a 10-year-old fleet and it picks up the same config.

The newer GRP2601 is the spiritual successor; if you are starting fresh in 2026, the GRP2601 has PoE (this does not), modern Opus codec (this does not), and a slightly faster firmware path. Pick GRP2601 for new deployments, GXP1610 to extend an existing one or when budget is the only consideration.
