Hello, who's speaking? The COMFORT 550A IP BASE is a telephone system for home offices and small businesses.

  • The phone book of the COMFORT 550A IP BASE has space for 500 entries, with Google and Microsoft 365 account integration you can save 1,000 additional contacts each.
  • Practical - and beautiful at the same time: The intuitive web user interface was honoured with the iF Design Award.



Better seen: With the COMFORT 550A IP BASE you have everything in view

Look at this! The Gigaset COMFORT 550A IP BASE is a real eye-catcher, and at the same time you can keep an eye on everything with this cordless phone. It impresses with its perfect ergonomics and timeless, elegant design. The large, high-contrast 2.2" colour display with customisable lighting and colour schemes is also impressive. During the dialling process, the display switches to jumbo mode, so you can see the fonts and numbers in extra large size: after all, good communication is not a question of age. A notification LED informs you of missed calls. The COMFORT 550A IP BASE is also easy to use in the dark or in difficult lighting conditions: The keypad and special keys are illuminated in the background.

Speak better: Free hands and full comfort during calls

Please stay on the line! With the Gigaset COMFORT 550A IP BASE, calls can last a little longer: several convenient functions make calls even easier and more pleasant for you. With the integrated hands-free function, for example, you can run errands on the side or let others listen in or speak. The sound quality is still first-class. You can also make hands-free calls with your favourite headphones thanks to the 3.5 mm headset connection. The detachable belt clip is also practical: This means you always have the handset with you and still keep your hands free. What's more, the COMFORT 550A IP BASE is hearing aid compatible, so your conversations are free from annoying noises.

Better configured: The web interface of the Gigaset COMFORT 550A IP BASE

It's really easy! You often hear sentences like this, they're easy to say. But sometimes it takes a little longer than expected. Unless you have help from the new design award-winning Gigaset Web Configurator: With its intuitive user interface, setting up the Gigaset base station is quick and easy. It can be conveniently operated via PC, smartphone or tablet. And with access to the Gigaset assistants, it guides you through language and country selection, setting up VoIP connections or registering handsets. One step at a time, step by step. Call diversions and DECT repeaters are also set up with ease. User-friendliness is the top priority, so the COMFORT 550A IP BASE is completely customised to your needs.

Better designed: The design of the award-winning web configurator

That's beautiful! When it comes to design, Gigaset focuses on combining aesthetics and functionality: It's not just about beautiful surfaces, but above all about usability. You can see that in the completely redesigned web user interface of the IP BASE, for example: We have improved its start-up and interaction with contacts and calls with more intuitive and user-centred features. Gigaset was honoured for this with the iF Design Award, one of the most prestigious design prizes in the world. The International Forum Design in Germany also recognised the design of the COMFORT handsets: With clear lines, distinct surfaces and high ergonomics, they are also better designed.

Better organised: The three answering machines of the Gigaset COMFORT 550A IP BASE

One is good, three is better! The Gigaset COMFORT 550A IP BASE has three answering machines, each with a recording time of 30 minutes. This has many advantages: The clear allocation of private and business calls makes everyday life much easier, so no more messages are lost. You are even better organised if colleagues, employees or family members are assigned their own telephone numbers and answering machines: This is also possible with this base station from Gigaset. And how do you deal with three answering machines? No different than with one: Operation is very simple via the web interface or via the Gigaset HX handset (CAT-iq 2.1). Whichever you prefer.

Better control: Be more independent with three answering machines

It rings! And rings and rings... With the Gigaset COMFORT 550A IP BASE's three answering machines, you're guaranteed never to miss a call - no matter what time of day. Make yourself independent of incoming calls - the Gigaset base station's web configurator takes care of contact management. It controls the answering machine according to your wishes, your announcements are configured in 15-minute intervals for each day of the week. After business hours or at the weekend, your calls can be automatically diverted to answering machines. The length of the recorded messages and customised messages can also be set up and configured to suit your needs.

Better storage: The phone book of the Gigaset COMFORT 550A IP BASE

Can you give me your number? You often hear this - even if you don't hear from each other later. The base station of the Gigaset COMFORT 550A IP BASE helps you maintain your contacts: In addition to the local phonebooks of the connected Gigaset HX handsets, it offers a central phonebook for up to 500 entries. If you have even more contacts, thanks to the integration of Google and Microsoft 365 accounts, 1,000 additional contacts can be saved. So no numbers or contacts are lost. Calls are initiated directly from the handset by simply clicking on the phone number in the web configurator: this keeps you flexible and is also very user-friendly. Communication can be so simple.

Better protected: No nuisance calls thanks to call protection

Peace and quiet at last! There are phone calls that you are not so happy about, that may even be annoying or fraudulent. With Gigaset call protection, such unwanted calls can be blocked automatically. With this function, you can easily add 100 numbers in the handset and up to 1,000 numbers in the base station to the blacklist: Calls from these numbers will then no longer be put through. If you wish, Gigaset call protection can also block anonymous calls: This means that if someone calls you without a transmitted phone number, they will not be able to reach you either. This prevents unwanted advertising or scam calls and effectively protects your privacy.

Better is better: More compatibility and flexibility when making calls

Where's the phone again? With the Gigaset COMFORT 550A IP BASE, you always have one to hand. The base station is perfect for your home, home office or small business. You can connect up to six Gigaset HX handsets to it, which are best distributed in several rooms: in the kitchen, dining room, bedroom or work areas. As the Gigaset IP BASE is connected to the router via LAN, you can set it up in a place with the best wireless coverage. And if you need more range, simply integrate a Gigaset DECT repeater into the system. Incidentally, you can make up to four calls at the same time with the IP BASE, and internal calls are also possible at any time.
