A 4.3-inch color screen, 16 SIP accounts, dual gigabit, built-in dual-band Wi-Fi, built-in Bluetooth, 24 programmable keys, and a USB port. The GRP2614 is the phone Grandstream built to undercut the Yealink T46U on every spec sheet — and it mostly succeeds.
The GRP2614 is our standing recommendation for any new mid-tier Grandstream deployment. Spec-for-spec, it goes head-to-head with the Yealink T46U (our most-shipped Yealink) and matches or beats it on almost every meaningful axis: 16 SIP accounts (same), 4.3-inch color screen (same resolution, slightly different aspect), dual gigabit (same), USB host port (same), built-in dual-band Wi-Fi (T46U requires a $30 dongle), built-in Bluetooth (T46U requires a $25 dongle), and a small 2.4-inch secondary screen for BLF (T46U does paperless DSS on the main screen instead).
The catch — and there is always a catch with Grandstream — is build quality and firmware polish. The T46U feels slightly heavier and more solid under the hand; the GRP2614 plastic is lighter and creakier. The Yealink web UI is more refined and the OTA firmware update process is more reliable. Neither difference is a deal-breaker for most deployments, but if you have an executive-floor desk where the phone is going to be visible and touched constantly, the T46U is the safer pick.
Where the GRP2614 wins clearly: any deployment that needs Wi-Fi or Bluetooth on a meaningful percentage of desks. Built in, no dongles, no SKUs to track, no lost adapters in a year. Also any deployment where price-per-desk is the binding constraint — the GRP2614 lands roughly $30 cheaper than the T46U at quantity, which adds up fast at 50+ phones.
Where to skip it: if you need expansion modules (the GRP2614 supports the GBX20 sidecar but maxes at 4 modules / 160 BLF keys — for more, step up to the GRP2615 / GRP2616), if you need a touchscreen (no touch model in this generation — Yealink T48U is the only real option), or if you absolutely need the most premium feel on the desk (the Yealink T54W or Poly Edge E450 are nicer-feeling phones at $40-80 more).

Plug the GRP2614 into PoE and ethernet. About a minute later it has registered to your extension. Same auto-provisioning flow as every other supported phone — no SIP credentials to type, no firmware to chase.
Boot, fetch config from our provisioning server, register, ready. About one minute on a normal connection.
16 lines per phone. Each line key has a dual-color LED for status at a glance.
24 multi-page keys + 2.4″ side screen mapped from the voip.army portal — BLF, paging, parking, transfer destinations.
Bringing your own? Send the MAC, factory-reset, plug in. No charge to add it to the fleet.
Standard PoE — any 802.3af-compliant switch from the last 15 years powers the phone without an adapter.
Provisioning template tested against every Grandstream firmware release for GRP2614. We catch regressions before they reach your fleet.
