Telephone Service Düsseldorf

Düsseldorf Telephone Service – Stay stylishly connected with COLLECTION

With the COLLECTION telephone service in Düsseldorf, you can remain reachable even when you’re not on site. We answer your calls in your company’s name – personally, professionally and reliably. The service is available at three locations: the Dreischeibenhaus, on Kaiserwerther Straße and, from the fourth quarter of 2026, at Le Coeur on Königsallee.

You’ll be provided with a Düsseldorf landline number, which our service team will use to answer your calls. We’ll forward relevant calls and discreetly log the rest. You’ll be notified via email, text message or a callback, as you prefer. Data transfer is GDPR-compliant.

The Düsseldorf telephone service is ideal for businesses that need a reliable call-handling service – whether on a permanent basis, during holiday periods, in the event of illness or when facing temporary peaks in workload. The service can also be seamlessly used as a replacement for an in-house switchboard.

In addition, we offer call forwarding: incoming calls can be forwarded directly to your mobile number, your office or another contact person within your company. This allows you to remain flexible and decide how you wish to be contacted.

Our three locations offer a prestigious business address with a professional reception service. At the Dreischeibenhaus, the COLLECTION Workspaces are situated on the 13th and 14th floors, offering views across the city. The Kaiserwerther Straße location offers views of the Rhine and is close to the airport. Le Coeur is currently under construction on Königsallee and will be ready for occupancy from the end of 2026.

On request, we can supplement the telephone service with additional services: postal service, virtual office address, company sign at the location, access to day offices, co-working spaces or meeting rooms. This turns a single telephone number into a fully-fledged location for your business presence in Düsseldorf.

All COLLECTION locations feature underground car parks, public transport links and a discreet service infrastructure. Your callers will experience a friendly first point of contact that reflects your company’s image – with no queues or changing voices.

It can even be set up at short notice: we’ll get your telephone service up and running within a few hours – flexibly, scalably and with no long-term commitment. This is a straightforward solution for temporary projects, start-ups or international branches.

With COLLECTION, you can take the pressure off your team, ensure you’re always reachable and maintain your professionalism – regardless of location, time or staffing levels.

Professional telephone answering service in Düsseldorf – COLLECTION Office Services

Whether you’re a business executive, a start-up founder or a self-employed person – the problem is all too familiar: your diary is full and one important meeting follows another. In the hectic day-to-day of work, there’s often hardly any time left for the phone, post or other administrative tasks. As a result, your inbox fills up and unanswered calls usually end up on your voicemail. Listening to these messages then falls by the wayside or is forgotten amidst the stress of everyday life.
However, being constantly available – in writing and by telephone – is essential for business success these days. Our solution: COLLECTION’s telephone and office service, because this ensures you are available to your customers, business partners and potential new clients round the clock, whilst you can focus on your company’s core business. You’ll be given a personalised, local telephone number for incoming calls, and our trained, friendly staff will answer your calls in your company’s name. If you wish, your callers can be put through to you directly, or messages can be recorded for you. This ensures that no important information is lost.


With COLLECTION, you can ensure professional, round-the-clock availability without having to employ your own secretarial staff. Tailor your office service requirements to your individual needs and save significantly on costs, as with us you only pay for what you actually use.
