How is the GXP1630 different from the GXP1628?

Bigger 320×240 graphical screen (vs 132×64 segment LCD), 3 SIP accounts (vs 2). Same 8 dual-color line keys. About $10 more — usually worth it.

Does the GXP1630 support EHS for wireless headsets?

Yes, with a separate Grandstream EHS adapter (about $30). Compatible with Plantronics and Jabra wireless headsets using standard EHS cables.

Can it use a USB headset?

No. No USB port on this model. Wired RJ9 or EHS-adapted wireless only.

How does it compare to the modern GRP2613?

The GRP2613 (~$130) has a color screen, USB port, 24 multi-page programmable keys, and modern silicon. About $40 more, but a meaningful step up for new deployments. The GXP1630 is the right pick for extending existing fleets.

Why the GXP1630 is on the catalog.

The GXP1630 is the top of the GXP1600 family. Bigger screen than the GXP1628 (320×240 graphical LCD vs 132×64 segment LCD), a third SIP account, same eight dual-color line keys for BLF. The screen upgrade is meaningful — full-page caller ID with photo, readable menus, browsable directory.

Where it sits in the catalog: between the GXP1628 (entry-mid) and the GXP1760 (5 lines, color screen). It is a phone for desks where you need 3 lines, real BLF capacity, but you do not need a color screen or USB. Common in small-office reception roles where the phone has been on the desk for 5+ years and replacement-with-equivalent is the priority.

Modern equivalents: the GRP2613 (3 lines, 24 multi-page programmable keys, USB, gigabit, color screen, ~$40 more) is the modern next-generation phone. For new deployments the GRP2613 is the much smarter buy; the GXP1630 is the right pick for extending existing fleets, or where budget constraints make the $40 difference real.
