The versatile line-up meeting every requirement

The COMfortel D-Series consistent, clean design is distinguished by a timelessly elegant style and a small footprint.
Whether entry-level or high-end phone - across all devices, the basic feature set enhances your professional communication claim.

The headset port offers high comfort and mobility while making calls.
Best audio quality is guaranteed with all phones thanks to wideband technology.

Call handling and user interface are consistent across the D-Series and intuitively lead to the right operation without training time. The professional feature set in combination with the customisable and self labeling function keys make everyday work easier and increase the productivity of your employees.
Conferences with up to three participants are possible.

The open SIP standard offers advantages such as compatibility, security, sustainability and investment protection, and enables easy integration into existing solutions. The D-Series owes its tremendous flexibility and versatility to an optimised integration of the light yet efficient scripting language Lua to meet any project requirements. A fully featured native VPN client, dual stack IPv4/IPv6 and the integrated Ethernet Switch reduce investment and maintenance costs in the IT infrastructure. The highly time-saving installation through zero-touch provisioning without rebooting as well as the neat web interface complete the professional profile and ensure easy and costefficient deployment and administration.

What our happy customers say

Above all, easy to use

"In addition to our smartphones, a land line telephone must make our working day easier, look attractive and, above all, be easy to use. Forwarding a call or holding a three-way call all work at the first go, even if you've never used a COMfortel D-Series telephone before."

Professional equipment is what really matters in office life

"In critical situations, it's always particularly helpful to be able to call the customer in person. It helps sort things out quickly without any added complications. Then, it's even more important to have professional equipment like the D-400 to hand, because it can be used immediately and can handle all the challenges that arise in the course of "daily business".

I like to wear a wireless headset when I'm on longer calls, so that I can take the calls directly when necessary. My desk-top D-400 has an LED which can be seen from any direction, and shows I'm on a call. That's really useful!"
