Grandstream GRP2624A real receptionist console.

Why the GRP2624 is on the catalog.

The GRP2624 is Grandstream's purpose-built receptionist phone. The 24-key BLF panel on the right of the main screen paginates to 96 effective native keys (4 pages × 24 keys), and you can stack up to 4 GBX20 sidecars on top of that for 256 BLF positions total — enough to monitor every coworker at a 200-person office on one phone.

The dedicated EHS port (something most GRP phones do not have built-in) makes this the right phone for any operator who lives in a wireless headset all day. Plug in a Plantronics CS540 or Jabra Engage 75 with an EHS cable, and the phone-handset and headset controls integrate properly: answering on the headset disengages the cradle hook, ending the call returns the phone to idle, etc. On most other GRP models you have to add a Grandstream EHS adapter dongle (~$30) to get the same behavior; the GRP2624 has it native.

Where it makes sense over the GRP2615 / GRP2616: any reception desk with more than 30 BLF buddies, any operator who uses a wireless headset all day, any deployment where pagination of BLF keys is acceptable (the GRP2624's 24-key panel paginates; the GRP2615's 40-key panel is always-on-screen). For pure 'show me everyone at once' BLF, the GRP2615 with its 40-key native panel can be a cleaner UI; for sheer key count and wireless-headset integration, the GRP2624 is the right call.
