Is the GXP2130 sidecar (GXP2200EXT) different from the GBX20?

Yes. The GXP2200EXT is the older paged-LCD sidecar used by the GXP2100 family (GXP2130/2135/2140/2170). The GBX20 is the modern sidecar for the GRP family. They're not interchangeable — pair the right sidecar with the right phone.

How is the GXP2130 different from the GXP2135?

The GXP2135 has 4 SIP lines (vs 3), the same 32 effective programmable keys, and slightly better firmware polish. About $40 more.

Does it support Wi-Fi?

Not built-in. The GXP2140 supports Wi-Fi via USB dongle. For built-in Wi-Fi, the modern GRP2614 / GRP2615 are the equivalent.

Will it auto-provision on voip.army?

Yes. Same XML provisioning as the rest of our Grandstream catalog.

Why the GXP2130 is on the catalog.

The GXP2130 is the entry-point of Grandstream's pre-GRP enterprise-class line. Compared to the GXP1700 family it adds three meaningful features: a 2.8-inch color screen (vs. 200×80), multi-page programmable keys (32 effective vs. 8 fixed), and built-in Bluetooth. It also keeps the GXP-series sidecar (GXP2200EXT) compatibility, which lets you stack up to 4 expansion modules for receptionist-class BLF.

This is the model in the legacy GXP catalog you would actually still recommend for new deployments where the modern GRP-series is not preferred (some long-standing PBX deployments require a specific firmware family, for example). 3 SIP lines, 32 effective programmable keys, real Bluetooth, sidecar-ready — it covers most desks at most businesses.

Modern equivalent: the GRP2614 (~$10 more) is functionally a direct generational replacement with bigger screen, more lines (16 vs 3), built-in Wi-Fi, and USB. For any new deployment we recommend the GRP2614 instead. The GXP2130 is the right pick when matching existing fleets or when the GXP-style key layout is the requirement.
