UC Today puts Snom’s latest conference phone to the test

Snom C520 WiMi Conference Phone Review

The Snom C520 – WiMi is the German Telecoms Developer’s new conference phone designed to deliver cost-effective conference calling support to a wide variety of businesses.

Featuring advanced DECT and Bluetooth Technology, the C520 claims to be one of the most reliable and innovative conference phones available on the market and delivers a unique set of features to help drastically improve business communication in a number of different ways– but how much truth is there in these claims?

In order to find out, we’ve decided to do a review on the product and test how well it lives up to Snom’s reputation as one of the world’s leading producers of high quality business phones.

How does it look?

With its innovative design, three context sensitive keys and graphical backlit display (158 x 57 pixels), the C520 would make a perfect centrepiece for any conference or meeting room and manages to condense a wide variety of cutting edge features into its compact, user-friendly setup.

What can it do?

As a full duplex conference device, the Snom C520 transmits HD sound through high-quality speakers and offers top-of-the-line in-built (and remote) microphones to ensure all conversations are crystal clear in quality from start to finish.

Fitting seamlessly into any working day, the C520 features two detachable DECT microphones that can be freely placed around the room to ensure maximum audio coverage through every call so that no participant goes unheard.

By supporting up to 3 SIP identities, all with simultaneous call management, the C520 offers unparalleled flexibility while its Bluetooth and DECT technologies also enable users to easily connect compatible smartphones to maximise the conference calling experience.

Built for reliability the C520 also provides up to 70 hours of standby time on a single charge, with microphones able to run continuously for up to 12 hours to ensure no conference call is cut off prematurely.

Though primarily built for smaller conference rooms, the C520 also offers wireless expansion with the addition of up to three C52 wireless speaker units to provide long-term support for businesses as they go through periods of growth.
