The 32 programmable keys are what make the GXP2135 our default office phone. With eight lines and four SIP accounts, it has enough room for a main number, a shared line, and the extensions a small team actually dials, and the keys put those appearances on the desk instead of behind a menu. We recommend it first because it covers the common office job without making you pay for an executive touchscreen.
The rest of the hardware supports that role. Dual Gigabit Ethernet ports with built-in PoE mean one cable can carry both data and power, and the included universal power supply covers a desk without PoE. Bluetooth is a useful extra for pairing a headset or a mobile device, and the HD handset and full-duplex speakerphone are the right baseline for conference calls. The color screen handles the basics, though the keys do the real work.
Setup is the one place where the GXP2135 asks for a little patience. The web interface is where most of the configuration lives, and it is not as polished as the phone itself; once a provider profile is loaded, day-to-day changes are straightforward. We think that is a fair trade for a phone that handles four SIP accounts, Gigabit, and Bluetooth at a midrange price. For a team standardizing on a practical handset, it is the one we reach for first.
Pros
- Eight lines and four SIP accounts
- 32 programmable BLF keys
- Gigabit PoE and Bluetooth
- Strong value for a small office
Cons
- Small 2.8-inch display
We recommend the GXP2135 as the default office phone when you need four SIP accounts, plenty of programmable keys, and wired reliability without paying executive-phone money.
