Grandstream GRP2601The cheapest name-brand SIP phone we ship.

Why the GRP2601 is on the catalog.

The GRP2601 is Grandstream's answer to the question every operations manager asks at some point: 'what is the absolute floor for a real SIP phone, not a $19 closet-brand thing that will brick after a firmware update?' Two lines, a small backlit LCD that shows you who is calling, a wired handset that feels solid, and PoE so you do not have to find a free outlet under every desk. It is the kind of phone you put on a warehouse counter, a break-room wall, a hotel front desk — anywhere a call needs to come in and out, and nobody is going to spend more than a minute a day looking at the screen.

Where it makes sense over a Yealink T31P: price, mostly. The T31P is a slightly better phone — bigger 2.3-inch screen, four lines instead of two, slightly nicer-feeling handset — but the GRP2601 lands roughly $15-20 cheaper at quantity, runs the same Opus and HD voice codecs, and provisions on the same XML config files Grandstream has been shipping since the GXP1600. If you are buying ten or fewer phones, get the T31P; if you are buying fifty for a call center that is mostly headset users anyway, the GRP2601 saves you a meaningful chunk of money.

Where it does not make sense: anywhere someone is going to want BLF keys to monitor coworkers, anywhere you need Bluetooth for a wireless headset, anywhere the boss might see it. It looks exactly like what it is — the cheapest phone in the catalog. The visual upgrade to the GRP2602 (color screen, larger body) for about $10 more is worth it if optics matter at all.
