Is the GXP1615 the same as the GXP1610 but with PoE?

Yes, exactly. Same body, same screen, same SIP capability, same codecs — just adds a PoE class 2 power input. About $10 more.

Should I get the GXP1615 or the GRP2601?

The GRP2601 is the modern equivalent — same price tier, but with the Opus codec, a slightly faster processor, and longer firmware-support runway. For new deployments, get the GRP2601. The GXP1615 is the right pick only if you're extending an existing GXP fleet and need provisioning compatibility.

Does it have BLF keys?

Not really. The 2 line keys can technically do BLF, but you'll usually want both for your SIP lines. For real BLF capability, look at the GXP1620 / GXP1625 (with bigger screens and more keys) or the modern GRP2603 / GRP2604.

Will it auto-provision on voip.army?

Yes. Same XML provisioning format as the entire GXP / GRP line. We pre-configure SIP credentials before shipping.

Grandstream GXP1615The PoE version of the workhorse.

Two SIP lines, a 132×48 backlit LCD, dual 10/100 ethernet, three XML soft keys, and PoE class 2. The GXP1615 is the GXP1610 with PoE added — a small upgrade that pays for itself on the first deployment where you do not have to buy 50 wall warts.

Grandstream GXP1615 voip desk phone — front view with handset and display — Grandstream GXP1615

Why the GXP1615 is on the catalog.

The GXP1615 is the GXP1610 plus a PoE controller, and roughly $10 more. That is the entire feature difference. If your deployment has PoE switches (almost all modern office switches do), the GXP1615 is the better buy — you save the cost and clutter of a power brick per desk, and you get cleaner cable runs.

On a 50-phone deployment, that is $150-250 in power adapters you do not have to buy, and 50 fewer wall warts taking up outlet space. The math works out almost immediately at scale. For single-unit and very small deployments where the GXP1610's included power brick is more convenient, the GXP1610 is fine — but for anything 10+ phones we recommend the GXP1615 by default.

Same caveats as the GXP1610: no Opus codec, no color screen, no Bluetooth, no BLF buddy keys beyond the two SIP lines. It is a basic two-line phone for desks where the user does not spend real screen time on the phone. For modern deployments with the same budget, the GRP2601 (PoE class 1, Opus support, slightly faster firmware) is the smarter pick at the same price tier.
