What it is and why consider it
Poly Edge E400 is intended for an operator who wants a dedicated secondary contact display. Compare the number of physical controls with the number of identities shown across pages; a SIP-line capacity is not a promise of simultaneous carrier calls.
Reasons to choose something else
Compare a single-display E300 if the second panel would be unused. More presence contacts also require suitable PBX subscription and provisioning support.
Deployment and acceptance checks
Test a held call, an attended transfer and message waiting with the approved provider template. Confirm USB headset controls and any expansion module after a cold boot. If the screen has paged contacts, have the intended user find a busy colleague during a live call.
Record the ordered model, hardware revision, installed firmware and calling platform together. Confirm administrator and provisioning ownership before connecting a previously used device. Keep the previous configuration and a supported recovery method before changing firmware; an arbitrary downgrade can remove security fixes.
Firmware, support and evidence
Use the linked HP Poly support resources to match the device to its approved firmware and provisioning instructions. The facts above come from manufacturer documentation; no hands-on measurements, current price or merchant offer are implied.
Where the table does not specify display, SIP-account capacity, network ports, PoE, Wi-Fi, Bluetooth, codecs, headset or expansion support, that field remains unverified for this record. A base station, handset and accessory have different responsibilities; do not copy a feature between them. Confirm lifecycle notices and support entitlement before a fleet purchase.
