Overview

A light DECT headset without a desk base

The Savi 7300 UC has the same light build as the Office branch, but instead of a desk base it connects through a small D400 USB adapter. The headset is therefore not tied to one desk and can be taken to another site. For a contact centre with no desk phones it is a simpler and cheaper answer than the Office branch.

The adapter reaches less far than the base

This is the difference that is easily missed. While the Office branch reaches up to 180 metres in open space and 55 metres in an office, the UC branch with the D400 adapter manages only 137 and 40 metres. The adapter is a small USB part with a smaller antenna than a desk base. For desk work and walking the immediate area that is enough; for moving around a whole building the Office branch is the better fit.

Acoustic Fence and specific encryption parameters

The microphone uses Poly Acoustic Fence technology against voices from neighbouring desks. This range also has specific security parameters, that is 256-bit AES encryption with 128-bit authentication. On the other Savi ranges it states only a general DECT security certification.

Strengths and limits

Strengths

DECT without a desk base, so the headset is portable
Security with 256-bit AES and 128-bit authentication
Up to 52 hours on standby and a charge in under 2 hours
A charging stand and a travel case are in the box

Limits and what to tell the customer

The range is shorter than on the Office branch, 137 m open and 40 m in an office against 180 and 55 m. The difference is the D400 adapter against a desk base.
The headset cannot connect a desk phone. The D400 adapter serves a computer only.
This is the previous generation. A new deployment belongs with the current 7400 range.
The D400 adapter is small and easy to lose. Without it the headset does not work with a computer. We carry a spare under code 8J8V7AA#ABB.

⚑ atlantis note

The UC branch has a different range: ask where the user walks

This is the most common disappointment with this branch. The D400 adapter reaches less far than a desk base, roughly 40 metres in an office instead of 55. If the user walks the whole floor or between floors during a call, offer the Office branch, or it comes back as a complaint about dropouts.

Order a spare D400 adapter up front

Adapter 8J8V7AA#ABB is a small USB part without which the headset does not work with a computer. For a multi-user deployment we recommend keeping one or two in stock.

Security is a selling argument here

The 7300 range has specific encryption parameters, 256-bit AES with 128-bit authentication. On the other Savi ranges it states only a general DECT security certification. In tenders for banks, insurers and the public sector this documents more than the newer ranges do.

Who it suits

Recommended deployment
Recommended use	a light wireless DECT headset connected to a computer through a USB adapter, with a microphone using Acoustic Fence technology
Position in the portfolio	wireless DECT headsets for the office and contact centres; the UC branch of the 7300 range, the previous generation
How it differs from the Office branch	it connects through the D400 adapter instead of a desk base, so its range is shorter and it cannot connect a desk phone; the box adds a charging stand and a travel case

Good fit

Contact centres with no desk phones, where the user sits at a desk or walks the immediate area. Environments with a formal encryption requirement. Adding units at a customer already running the 7300 range.

Check

How far the user walks during a call; the range is shorter than on the Office branch. Whether they have a desk phone, in which case the Office branch applies. Whether they already run the 7300. How many spare D400 adapters to keep.

Consider another model

Savi 7300 Office or 7400 Office for more range and a desk phone, Savi 8200 UC for a larger driver and active noise cancelling, Voyager for Bluetooth, Mission for a wired solution.

The "Check" and "Consider another model" cards come from the experience of the atlantis team.

What the adapter connects

Computer

Through the D400 DECT adapter

The adapter plugs into a USB-A port. A USB-C adapter is also in the box, so the headset works with a newer laptop that has no USB-A port.

USB-A

USB-C via adapter

Desk phone

Not connected

The UC branch does not serve a desk phone. Anyone who needs one belongs with the Office branch and its desk base, which has a telephone interface.

Office branch only

Certifications

Verified platforms

The universal code has Microsoft Teams Open Office and Zoom certification. Supported operating systems are Windows 11, Windows 10 and macOS.

Microsoft Teams Open Office

Zoom

Do not count on Android or iOS for this range. For a mobile phone, the Office branch of the 7400 and 8400 ranges with Bluetooth in the base is the one.

Frequently asked questions

Why does the UC branch reach less far than the Office branch?

The difference is the D400 adapter against a desk base. The adapter is a small USB part with a smaller antenna. The UC branch reaches up to 450 ft in open space and 130 ft in an office; the Office branch 180 and 55 metres.

Does the headset connect a desk phone?

No. The D400 adapter serves a computer only. For a desk phone, the Office branch with its desk base and telephone interface is the one.

What if the D400 adapter is lost?

Without it the headset does not work with a computer. We carry a spare under code 8J8V7AA#ABB, and for a multi-user deployment we recommend keeping one in stock.

What about security?

This range has 256-bit AES encryption and 128-bit authentication. That is more specific than the general DECT security certification of the other Savi ranges.

Is the 7300 range still current?

No, the current one is the 7400 range. We carry the 7300 for customers who already run it and are adding units to their existing spare parts, which do not carry over between generations.
