Is this the right equipment for you?

Who the Z 21i IP Phone is actually for

Most equipment pages just tell you what a device does. Here's the honest version: when this machine is the right choice, when it's fine, and when you should look at something else. We offer equipment for every business need, but the right machine depends on your specific workflow.

Best fit

Pick this if...

  • You run Zultys MX and need cheap phones for break rooms, lobbies, or low-volume desks.
  • You want PoE so installation is one cable.
  • You only need two line keys per phone.
  • You're standardizing your low-tier phone choice across the fleet.
  • You manage everything centrally through Zultys MX Administrator.
Works fine

You'll be happy if...

  • You need a temporary phone while transitioning to a richer setup.
  • You want a basic SIP phone for occasional use.
  • You're okay with 10/100 Ethernet because you don't pass-through a PC.
  • You like wired-only setups without Bluetooth or Wi-Fi.
Look elsewhere

Skip this if...

  • You're not on a Zultys MX system.
  • The user handles real call volume — two line keys won't cut it.
  • You want color, programmable soft keys, Bluetooth, or Wi-Fi.
  • You need Gigabit pass-through for the desk PC.
  • You want video, touchscreen, or any printing capability.
Full specifications

Every spec, no guessing

The Zultys Z 21i is the entry-level IP phone in the Zultys lineup — 2.5-inch backlit graphical display, two dedicated line keys, dual 10/100 Ethernet (not Gigabit) with PoE. It's the phone you put in a break room, copy room, hallway, lobby, or on the desk of someone who picks up two or three calls a day. PoE keeps the install clean — one cable, no power brick. EHS headset support is there if someone wants wireless, and it integrates with the Zultys ZAC UC app for any desktop call control needs. The thing buyers regret: putting it on the desk of someone who actually uses a phone all day. Two line keys disappear fast, the screen is small, and there's no Bluetooth, Wi-Fi, color display, or programmable soft keys. For light call volume it's perfect — for anything more, jump to the Z 22G or higher. The other thing to know: it's 10/100 Ethernet, not Gigabit, so if you're chaining a PC behind it, that PC tops out at 100 Mbps. Like every Zultys phone, this is for the Zultys MX platform — don't repurpose it for a generic SIP environment.
