How many BLF buddies can the GRP2615 monitor at once?

40 natively (on the dedicated side panel), or up to 200 with four GBX20 sidecars attached. The native panel has multi-color LEDs (red/green/amber) for distinct call states; the sidecar uses single-color LCD labels.

Does the GRP2615 have a touchscreen?

No. Both displays are non-touch.

How does it compare to a Yealink T54W + EXP50?

Similar capability — the T54W with one EXP50 sidecar gives you ~60 BLF keys total. The GRP2615 has 40 native + room for 4 GBX20s = 200 max. Better key count, lower price (~$190 vs ~$330 for the T54W+EXP50 pair). Yealink has a slight edge on build quality.

Is the side panel monochrome or color?

Color. 2.4-inch color LCD with multi-color LED key indicators.

Can I label the keys with paper inserts?

No — labels are software-defined on the side screen. Change them in the voip.army portal; the phone reloads instantly. Saves the labeling-tape ritual every reception desk used to do.

Grandstream GRP2615 voip desk phone — front view with handset and display — Grandstream GRP2615

Why the GRP2615 is on the catalog.

The GRP2615 takes the GRP2614 chassis and upgrades the secondary display from a 24-key DSS pad to a 40-key multi-color BLF panel — five rows of eight keys each, with red / green / amber LED indication per key. For a reception desk monitoring 30-40 coworkers, that is enough to fit your entire monitoring set on the home screen without paging. For larger floors, you can stack up to 4 GBX20 sidecars (160 more keys) for a total of 200 BLF positions on one phone.

The pitch: this is the closest Grandstream gets to a dedicated receptionist console. The Yealink equivalent is the T54W + EXP50 sidecar combo (~$330 combined for similar key count); the Poly Edge E550 sidecar pairs around $400. The GRP2615 with native 40-key BLF lands around $190 — meaningfully cheaper, and the multi-color LEDs are arguably the best in this price tier (DND, busy, ringing, hold, transfer-pending all visually distinct).

Where it makes sense over the GRP2614: any desk where the user has 15+ BLF buddies to monitor at a glance — receptionists, executive assistants, dispatchers, anyone running call queues. The GRP2614's 24-key paged BLF requires you to flip pages constantly; the GRP2615's 40-key native panel is always-on-screen. For users with fewer than 10 BLF buddies, the GRP2614 saves you ~$50 and is the smarter buy.
