Description

A phone that needs neither socket nor cable

The Edge E350 is the only one of the three E300 models with Wi-Fi. That changes how it is deployed: the phone can stand anywhere there is mains power and joins the network wirelessly. It suits hot desks, meeting rooms, receptions in listed buildings and anywhere running a network socket would cost more than the phone itself. Watch the power, though: the phone is designed for PoE and no adapter is in the box, so a wireless deployment needs the supply solved separately.

Eight keys is the line you pay to cross

Eight line keys with pagination cover up to 32 SIP lines, which is enough for an ordinary user and for the head of a smaller team. If the customer needs to watch more lines at once, typically an assistant or a switchboard operator, the right choice is the E400 or E450 with two displays, or the E550 with a five inch display. The difference is not in the number of lines but in how many are visible without paging.

Three ways to connect a headset

The phone has an RJ-9 connector for a corded headset, an EHS port for a wireless DECT headset, and Bluetooth 5.0 for a wireless headset or a mobile. The hook switch needs the APP-51 adapter, which we carry under code 85Q60AA. On this model the USB-C port is for media and storage, not for a headset; a headset over USB is served by the E450 and E550.

Strengths and limits

Strengths

Wi-Fi 802.11ac, the phone needs no network socket at the desk
Bluetooth 5.0 for a wireless headset and for a mobile
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 E300, E320 and E350 that is code 8F3R2AA.
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.

Wi-Fi is the argument here, not a bonus

The difference between the E320 and the E350 is Wi-Fi alone, the phones are otherwise identical. The premium is worth it only where a network socket genuinely cannot be run, typically listed buildings, hot desks and temporary workplaces. On an ordinary office desk with a socket the E320 is cheaper and more dependable, because it does not rely on the quality of the Wi-Fi.

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 E300 and E320	it adds Wi-Fi 802.11ac; the E320 has Bluetooth only and the E300 neither, the three phones being otherwise identical

Suitable

Workplaces with no network socket at the desk, hot desks, receptions in listed buildings and temporary workplaces. Users who want to pair a wireless headset or a mobile with the phone.

Verify

Whether the customer has a PoE switch with budget left on the port. Whether a desk socket is genuinely missing, otherwise the cheaper E320 will do. How many lines the user must see without paging. Whether wall mounting is needed.

Consider another model

Edge E320 where Wi-Fi is not needed, Edge E450 for an assistant or operator with two displays, Edge E550 with a five inch display, Poly Rove for a DECT phone that moves around the building.

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: if there is one at the desk, the cheaper E320 without Wi-Fi will do
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 8F3R2AA kit is not in the box
Bulk deployment: Poly Zero Touch Provisioning and Poly Lens, agree the configuration beforehand

The atlantis team helps with every point. From verifying the network and PoE, through choosing the model by the user's role, to bulk configuration and training.

Management and services

Poly Lens: inventory, bulk settings, firmware updates and an overview of the deployed phones; first deployment is served by Poly Zero Touch Provisioning
Poly+ Partner: local support from an experienced certified team in Czech, by phone, chat, web and video call, priority device replacement in which the manufacturer ships the replacement part the next business day and pays the shipping, all under the terms of the programme and for its whole validity, so care can continue even after the warranty ends
atlantis deployment: verifying the network and PoE, choosing the model by the user's role, bulk configuration through Poly Lens, connection to the PBX or cloud service and training the users

Frequently asked questions

Is a power adapter in the box?

No. The Poly Edge E350 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 E300 and E320?

The Poly Edge E350 adds Wi-Fi 802.11ac. Code 82M88AA, the E320, has Bluetooth 5.0 only, and code 82M92AA, the E300, has neither. The display, key count and audio are identical across all three.

Can I connect a wireless headset to the phone?

Yes, in two ways. A Bluetooth headset pairs directly, while a DECT headset such as a Poly Savi connects by RJ-9 and needs the APP-51 EHS adapter for automatic call answering, which we carry under code 85Q60AA.

How many lines does the phone handle?

The Poly Edge E350 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.
