Poly Edge E450 Desktop Business IP Phone

Every specification below is taken from HP and Poly's own published documentation for the Poly Edge E450 — the HP product-details and product-specifications pages, the HP ProductSheet and the Poly datasheet. Where HP does not publish a figure we have left it out rather than estimate it.

Platforms and certifications

The Poly Edge E450 is an Open SIP desk phone. It registers against hosted and on-premise SIP platforms — 3CX, Asterisk and FreePBX derivatives, BroadWorks and Metaswitch-based hosted services, and the SIP trunking services offered by Singapore carriers.

HP publishes no Microsoft Teams, Zoom or Google Meet certification for any model in the Edge E range, and we do not claim one. Where a Microsoft Teams certified desk phone is the requirement, the Poly CCX Teams Edition models are the correct line — see the CCX 350 for Microsoft Teams.

Wireless and device connectivity

Integrated Bluetooth 5.0, Wi-Fi on 2.4 GHz and 5 GHz bands, and NFC.

Headsets

1 x RJ-9 headset port; 1 x Electronic Hook Switch (EHS) port; Bluetooth and USB headsets also supported

Provisioning and security

The Edge E series supports HTTPS provisioning with encrypted configuration files and signed software, 802.1X network authentication, SRTP media encryption and TLS signalling — the controls a Singapore IT team needs to put a phone estate on a corporate VLAN without exceptions.

Management software

HP states “Simple set up and support with Poly Lens” for the Edge E series. Poly Lens is HP's cloud device-management service: from one console your IT team can see device health, push firmware, apply configuration profiles and pull usage insight across every Poly device in the estate, phones and meeting rooms alike.

What is the difference between the Poly Edge E450 and the Edge E400?

Wireless. Both share the same 3.5-inch main and 2.4-inch secondary displays, 14 line keys and 44 line key assignments, Class 4 PoE, single USB Type-C port, RJ-9 and EHS headset ports, and support for one expansion module. The E450 adds integrated Bluetooth 5.0 and Wi-Fi on the 2.4 GHz and 5 GHz bands; the Edge E400 has NFC only.

Which Wi-Fi standards does the E450 support?

HP's published band table lists 2.4–2.4835 GHz (802.11b, 802.11g, 802.11n HT-20) and 5.15–5.825 GHz (802.11a, 802.11n HT-20 and HT-40). HP's marketing copy for this model elsewhere refers to 802.11ac, which HP's own specification table does not list — we state the band table, because that is the published specification. If 802.11ac or Wi-Fi 6 support is a hard requirement, confirm it with us before ordering.

If I deploy the E450 over Wi-Fi, how do I power it?

With an optional Poly power supply, ordered separately — PoE cannot supply a phone that is not on Ethernet. HP specifies IEEE 802.3af Class 4 PoE at 13 W maximum for wired operation. Tell us the deployment mode at quotation stage and we will include the correct regional power supply.

How many contacts can the E450 display, with and without an expansion module?

Up to 44 line key assignments across the two built-in displays. Adding the one supported Poly Edge E Expansion Module (2200-87020-025) brings a further 22 keys across three pages, for up to 66 additional contacts. For a position that needs two modules, step up to the Edge E550.

How does the E450 compare with the Edge E550?

The Edge E550 replaces the dual-display arrangement with a single 5-inch colour display, raises the key count to 12 keys and up to 48 line key assignments, adds a second USB Type-C port and supports two expansion modules instead of one. Both carry Bluetooth 5.0 and Wi-Fi. Choose the E450 if the portrait busy-lamp screen suits the operator's workflow; choose the E550 for maximum key capacity.

Is a wall mount or power supply in the box?

Neither. HP lists the setup sheet, console, handset and handset cord (all with Microban antimicrobial protection), CAT-5E network cable and desk stand. A wall mount bracket covering the E400, E450, E500 and E550 is ordered separately.

Is the Edge E450 certified for Microsoft Teams or Zoom?

HP publishes no Microsoft Teams, Zoom or Google Meet certification for any Edge E model, and we do not claim one. The Edge E range is Open SIP. For a Teams-certified desk phone, see the Poly CCX Teams Edition models such as the CCX 350 for Microsoft Teams.

Does the Poly Edge E450 come with a Singapore warranty and GST invoice?

Yes. Every Poly Edge E450 sold by SourceIT comes with local Singapore warranty and a GST invoice.
