Description

A phone for a desk with a network socket

This model joins the network by cable only, it has no Wi-Fi. For an ordinary office desk with a network socket that is the right choice, because the phone does not depend on the quality of the wireless network and draws its power from the same cable. Watch the power: the phone is designed for PoE and no adapter is in the box. If the customer needs a phone where there is no network socket, the models with Wi-Fi are the E350, E450 and E550.

How many lines the user sees without paging

This model has 14 arranged 8 and 6 across two displays, up to 44 key assignments and up to 32 registered SIP lines. With desk phones what decides it is not the total line count but how many the user sees at once without paging. An ordinary user is served by the eight keys of the E300 to E350, an assistant or switchboard operator by the two displays of the E400 and E450, or by the large display of the E550. So ask about the user's role, not about the number in the price list.

Two ways to connect a headset

The phone has an RJ-9 connector for a corded headset and an EHS port for a wireless DECT headset, which needs the APP-51 adapter that we carry under code 85Q60AA. This model has no Bluetooth, so neither a Bluetooth headset nor a mobile will pair with it. Those are served by a model with a trailing two or five.

Strengths and limits

Strengths

A wired connection is steadier and cheaper than a wireless one
Both an RJ-9 connector and an EHS port, for corded and wireless DECT headsets
Two gigabit ports, a computer can be daisy-chained through the phone
802.1X authentication, SRTP media encryption and management secured by TLS and HTTPS

Limits and what to tell the customer

No power adapter in the box. The phone is designed for PoE, and a wireless deployment needs a supply ordered with it.
No wall mount kit in the box. For the E400, E450 and E550 that is code 8F3R3AA.
The USB-C port is for media and storage, not for a headset. A headset over USB is served by the E450 and E550.
The warranty is one year, shorter than the two years on most Poly headsets.

⚑ atlantis note

With phones, power is settled first, not last

The whole Edge E range ships without a power adapter and expects power over the network cable, that is PoE. Verify that the customer has a PoE switch and enough budget left on its ports. With the E400, E450 and E550, which sit in PoE class 4, that goes double. If there is no PoE, an adapter or an injector is needed and it is ordered separately.

When the customer wants a phone without a network socket

This model has no Wi-Fi. If the customer needs to put a phone where there is no network socket, offer a model with a trailing five, that is the E350, E450 or E550. The premium is worth it only where a socket genuinely cannot be run, typically listed buildings, hot desks and temporary workplaces.

Key count is about supervision, not line count

Customers tend to ask about the number of lines, but what decides it is how many they see without paging. Eight keys on the E300 to E350 is enough for a user. An assistant watching their manager's lines, or a switchboard operator, needs the E400 or E450 with two displays. Ask about the role, not the number.

Who it suits

Recommended deployment
Recommended use	the most versatile Poly phone, built for hot-desking or the home office, with the NoiseBlockAI and Acoustic Fence noise technologies
Position in the portfolio	desk IP phones, Edge E range, the mid-tier E300 class with both Wi-Fi and Bluetooth
How it differs from the other models in the range	it has two displays and fourteen line keys instead of eight, but it sits in PoE class 4 and has neither Wi-Fi nor Bluetooth

Suitable

Ordinary office workplaces with a network socket at the desk, where a dependable wired connection and power from a single cable are wanted.

Verify

Whether the customer has a PoE switch with budget left on the port. Whether there is a network socket at the desk, without which a Wi-Fi model is needed. How many lines the user must see without paging. Whether wall mounting is needed.

Consider another model

Edge E450 if Wi-Fi and Bluetooth are needed, Edge E550 with one large display, Edge E320 for an ordinary user with eight keys, Poly CCX for touch operation.

The “Verify” and “Consider another model” cards come from the experience of the atlantis team.

What to verify before ordering and deploying

PoE: does the customer have a PoE switch with budget left on the port, as no adapter is in the box
Network socket: this model needs one, without it order a Wi-Fi model, that is the E350, E450 or E550
Key count: ask about the user's role rather than the line count, an assistant needs the E400 or E450
Headset: corded over RJ-9, wireless DECT through EHS with the APP-51 adapter, Bluetooth directly
Wall mounting: the 8F3R3AA kit is not in the box
Bulk deployment: Poly Zero Touch Provisioning and Poly Lens, agree the configuration beforehand

Frequently asked questions

Is a power adapter in the box?

No. The Poly Edge E400 is designed for power over Ethernet under IEEE 802.3af, class 3, drawing up to 13 W. Neither an adapter nor an injector is in the box and both are ordered separately.

How does it differ from the other Edge E models?

The Poly Edge E400: it has two displays and fourteen line keys instead of eight, but it sits in PoE class 4 and has neither Wi-Fi nor Bluetooth. A full overview of all eight order codes is in the variants table at the top of this page.

Can I connect a wireless headset to the phone?

A DECT headset such as a Poly Savi, yes: it connects by RJ-9 and needs the APP-51 EHS adapter for automatic call answering, which we carry under code 85Q60AA. A Bluetooth headset, no, as this model has no Bluetooth.

How many lines does the phone handle?

The Poly Edge E400 has eight line keys with pagination and supports up to 32 registered SIP lines. If the user must see more lines at once without paging, the E400 and E450 with two displays or the E550 with a five inch display are the models.

Can the phone be wall mounted?

Yes, but the wall mount kit is ordered separately. For the E300, E320 and E350 the code is 8F3R2AA, and for the E400, E450 and E550 it is 8F3R3AA. The E100 and E220 have the mounting kit in the box.
