• Three page keys per module, providing up to 66 additional contacts/line appearances per expansion module.​

• Host-powered: PoE or AC power goes only to the phone; no separate power brick for the module.​

• Cloud PBX receptionist console

• Edge E500/E550 is registered to a hosted UC platform (SIP).  

• One or two Edge E Expansion Modules provide BLF keys for all departments, on‑net branches and executives.

• Lobby staff can see presence at a glance and connect visitors efficiently.​

• Contact center supervisor station

• Edge E500 with two modules used by a floor lead to monitor team extensions and queues.

• Campus or healthcare front desk

• Edge E450 with one module providing keys for critical locations (clinics, wards, security, maintenance).  

• Staff can quickly escalate calls and coordinate responses in real time.​

• Accessory Recommendations

  Edge E wall mount bracket (2200‑47410‑002): For installations where the Edge E phone and expansion module must be wall‑mounted, such as hallway stations or tight front desks.​  

• PoE switch or PoE injector: Ensures the host Edge E phone has sufficient power budget to drive one or two expansion modules along with its own features.  

• Cable management clips or trays: Helpful for multi‑module configurations to keep the phone, module and network/power cabling neat and serviceable.  

• Headsets for Edge E phones (e.g., HP Poly USB or RJ‑9 headsets): Combine with the expansion module to create a complete, ergonomic receptionist or agent workstation.

• Use‑Case Scenarios

  High‑volume reception desks: Hotels, corporate HQs and large campuses where one or two operators handle high inbound traffic and need instant visibility into dozens of extensions.  

• Departmental admins and executive assistants: Admins supporting multiple executives can map each key to an exec line, direct dial, or BLF, speeding coordination and call screening.  

• Healthcare and education front offices: Schools, clinics and hospitals where staff must reach security, facilities and key departments without hunting through directories.  

• Retail and multi‑site operations centers: NOC or operations teams that monitor multiple stores or sites can assign each line key to a store, manager or dedicated support number.
