Business Phone Models

Having an ESI business communications system lets you choose from among a variety of attractive and highly convenient ESI phones. Each is a great addition to virtually any office decor, but it’s far more than just a “pretty face.”

Each desktop model — whether ESI 60 Business Phone, ESI 40 Business Phone, or 24-Key Feature Phone — has a sealed membrane below the keys to make it virtually spill-proof; and the sturdy multi-position angled base lets it fit on any desk or counter space so you can easily see the status of the display and keys. Each ESI desktop phone also can be wall-mounted. The ESI 60 and ESI 40 models also include adjustable backlit displays, and the ESI 60 has a high-definition full-duplex speakerphone.

ESI’s Cordless Handset II provides mobility to users who are constantly on the move in the office. There are three models of the compact, lightweight Cordless Handset II, and each provides the same rich feature set as the 24-Key Feature Phone, plus ESI’s exclusive Quick Switch™ for maximum ease when switching back and forth between your ESI desktop phone and your Cordless Handset II.

The ESI Cordless Handset II uses advanced DECT 6.0 third-generation 1.9 GHz technology to provide mobility to the user who’s constantly on the move in the office. Like the original ESI Cordless Handset models, each ESI Cordless Handset II provides its user most of the rich ESI feature set along with the convenience of a portable device — with the added benefit of increased range of use, thanks to DECT’s ability to support repeaters. This lets users continue calls while moving between different coverage cells throughout a location, using a process known as handoff that’s similar to how cell phones work. When you return to your desk, a touch of ESI’s Quick Switch Key lets you toggle from the lightweight, portable Cordless Handset II back to your full-function ESI desktop phone.

The ESI Cordless Handset II comes in three different versions:

  • Digital
    • Systems: IP Server 900; ESI Communications Servers.
    • Programmable keys: 8.
    • VOICE MAIL key: Yes; dedicated.
    • HELP key: No.
    • Display: Two-line, 32-character, plus a third line with informational icons; backlit.
    • Speaker: Yes. Speakerphone: Yes.
    • Integrated headphone jack: Yes.
  • Local IP — Provides local IP telephony (i.e., LAN-only). Uses G.711 voice compression. The base station uses Power over Ethernet, to maximize your connection convenience.3

    • Systems: IP Server 900; ESI Communications Servers.
    • Programmable keys: 8.
    • VOICE MAIL key: Yes; dedicated.

Under DECT 6.0, each ESI Cordless Handset II operates on the 1.9 GHz frequency band, which has been specially allocated to support cordless telephony. Benefits of DECT 6.0 technology include:

  • Longer battery life (including longer standby time).
  • Support for Repeaters — Each base unit can be expanded to support up to six optional ESI Cordless Handset II Repeaters. This enables the user to significantly extend telephony coverage as compared to a traditional cordless telephone, by simply installing Repeaters in appropriate locations.
  • Encrypted radio traffic for higher call security.
  • Wi-Fi friendliness — DECT 6.0 technology enables use of ESI Cordless Handsets II within range of wireless home networking (or WLAN) systems without interference, a major advantage in the many businesses that also make use of WLANs.
