Is this the right phone for you?

Who the ZIP 45G 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 a reliable phone for receptionists or call handlers.
  • You want 21 programmable keys with EHS-supported headset port.
  • You need dual Gigabit Ethernet to pass through a PC connection.
  • You'll expand with the ZIP 450M module for attendant consoles.
  • You use the Zultys ZAC desktop app and want the deskphone in sync.
Works fine

You'll be happy if...

  • You like physical buttons and a backlit display, but don't care if it's monochrome.
  • You don't need Bluetooth at the desk and use wired headsets.
  • You handle moderate-to-heavy call volume but skip video conferencing.
  • You're rolling out a fleet and want a consistent mid-range standard.
Look elsewhere

Skip this if...

  • You're not on a Zultys MX system.
  • You expected a color screen — go with the Z 23GE or ZIP 47GE instead.
  • You need Bluetooth or Wi-Fi built in (the 45G has neither).
  • You want video calling or a touchscreen.
  • You're shopping for a printer or scanner — this is a desk phone.
Full specifications

Every spec, no guessing

The Zultys ZIP 45G is the workhorse Gigabit phone in the lineup — 21 programmable keys, a 3.7-inch backlit graphical LCD (monochrome, not color), and dual Gigabit Ethernet ports. It's the phone you put on the desk of someone who handles real call volume but doesn't need a touchscreen or color display. HD voice quality is noticeably better than the entry-level Z 21i, and the dedicated headset port with EHS support means wireless headsets work without fighting you. It plays nicely with the Zultys ZAC unified communications app for desktop call control. The 21 keys handle most receptionist and sales rep workflows, and you can add the ZIP 450M expansion module if someone needs more BLF lines later. The thing buyers regret: not realizing the display is monochrome until the box is open. If you wanted color, jump to the Z 23GE or ZIP 47GE. Also missing: built-in Bluetooth (the 47GE has it, the 45G doesn't) and any video capability. This is a Zultys MX phone — don't buy it for a Cisco, 3CX, or generic SIP setup expecting full feature parity.
