How is the GXP2170 different from the GRP2615?

Both have main + secondary screens. The GRP2615's secondary screen has 40 always-visible multi-color BLF keys (no pagination); the GXP2170's secondary has 6 keys × 8 pages (48 effective, but paginated). The GRP2615 also has built-in Wi-Fi (the GXP2170 needs a USB dongle) and uses the modern GBX20 sidecar. The GRP2615 is the cleaner choice for new deployments.

Does the GXP2170 support a touchscreen?

No. Both displays are non-touch.

Can it use a Wi-Fi dongle?

Yes. Grandstream's USB Wi-Fi dongle plugs into the USB port.

How many BLF keys with full expansion?

208 — 48 native on the side screen plus 160 across four GXP2200EXT sidecars.

Will it auto-provision on voip.army?

Yes. Same XML provisioning flow.

Why the GXP2170 is on the catalog.

The GXP2170 is the top of Grandstream's legacy enterprise catalog. Dual displays (4.3-inch main + 2.8-inch BLF secondary), twelve SIP accounts, a programmable-key layout that goes deep enough to be receptionist-capable without a sidecar (48 native keys on the side screen via 6×8 pagination), built-in Bluetooth, USB, support for up to 4 GXP2200EXT sidecars (160 more keys).

It is the GXP-family phone closest in capability to the modern GRP2614 / GRP2615. Twelve lines is plenty for almost any role (and matches the modern 16-line GRP minimum closely enough), the dual-screen layout puts BLF on dedicated real estate instead of competing with caller ID, and the build is the heaviest and most premium-feeling in the GXP line.

Modern equivalent: the GRP2615 is the closest direct replacement — bigger native BLF panel (40 multi-color keys vs the GXP2170's 6-key paginated), built-in Wi-Fi (none on the GXP2170 without a USB dongle), and the modern GBX20 sidecar instead of the older GXP2200EXT. About $40 less than the GXP2170, with more capability. For new deployments, the GRP2615 is the obvious better buy. The GXP2170 is the right pick for extending established GXP2170 fleets or matching existing infrastructure.
