D735 Desk Telephone Black


The Snom D735 SIP Color Deskset features an intuitive design with advanced technology and connectivity. Eight self-labeling programmable feature keys surround a 2.8- inch, 320 x 240 pixel color LCD display. Scroll between four pages of keys with a dedicated button. A proximity sensor reacts as your hand gets close to the phone to dynamically adjust the display. Opus codec support gives you the freedom to enjoy crystal-clear audio or high-quality narrowband audio, depending on your network conditions. Zero touch provisioning eliminates the need for manual labor typically involved with installation. Power over Ethernet (PoE) support and dual Ethernet ports makes the system cost-effective and easy to use. The USB port allows additional connectivity, including up to three D7 expansion modules for increased visibility and one-button options. The system features multiple configurations, including eight programmable feature keys, four soft keys and 15 dedicated feature keys.

The Brand

In the year 1997, Snom Technology GmbH was a Berlin startup and first in the world to
deploy professional VoIP devices. This has given Snom the first-mover advantage,
allowing the brand to grow in pedigree and scope to represent the world’s Premium
SIP VoIP Business Telephone category. Snom operates across the world and has a
sizeable fan base who helped Snom grow as a business while continually contributing
to evolving the technology and product ranges. The brand today occupies top mindshare as almost every professional VoIP expert in the world knows and recognizes
the brand Snom.
To articulate the meaning of ‘Snom’, the brand occupies the ‘Premium Category’ of
SIP business telephony devices and stands on two poles:
(i) First in VoIP, (ii) German Engineered.
Snom’s brand sits in four product categories:
1. Telephones (Desktop, DECT)
2. Conferencing
3. Headsets
4. Broadcasting
The technology can be enhanced with third party applications development through
the platform.


With 20 years of successfully developing desktop IP phones (like the Snom 190),
mobile DECT phones and conference devices for the global market, the Snom
product portfolio also features a comprehensive range of accessories.
However, it is not just our products that make us such a strong partner, but also
the range of services provided by Snom.
