Telephony that keeps pace with your everyday life

The IP DECT base station allows up to six DECT handsets to be operated simultaneously. This allows you to distribute the phones flexibly across several rooms and remain reachable everywhere. With up to four SIP accounts, private and business numbers can be used conveniently. Up to four calls can be made simultaneously, and internal calls between handsets are free of charge at any time.

The integrated HDSP™ technology with G.722 codec ensures clear and natural voice transmission. Calls sound clear and pleasant, even during prolonged use.

COMFORT 500HX – Convenient telephony and everything at a glance

The COMFORT 500HX included in the set impresses with its high user-friendliness and timeless design. The large, high-contrast 2.2-inch colour display ensures optimum readability. During dialling, the display automatically switches to jumbo mode, so that numbers and characters are displayed in a particularly large font. Ideal for anyone who values clarity and convenience.

The illuminated keypad and function keys enable safe operation even in poor lighting conditions. A notification LED reliably informs you of missed calls and new messages.

Hands-free, headset and hearing aid compatibility

For comfortable telephoning, the COMFORT 500HX offers an integrated hands-free function with excellent sound quality. This leaves your hands free for taking notes or other activities. In addition, a 3.5 mm headset connection is available for convenient telephoning with headphones.

The handset is hearing aid compatible and offers two acoustic profiles for clear, interference-free calls. The removable belt clip provides additional flexibility in everyday use.

Easy to set up with the web configurator

Setting up the Gigaset BasicLine IP + COMFORT 500HX is quick and easy. You can conveniently configure the base station via PC, smartphone or tablet using the integrated web configurator. Intelligent wizards guide you step by step through the most important settings, from Internet telephony and phone numbers to registering the handsets.

Even after commissioning, settings such as call forwarding, handset management and software updates can be clearly managed. This means that the system can be adapted and kept up to date at any time.

Security you can rely on

The Gigaset BasicLine IP uses modern security standards to protect your calls and data. Digital DECT encryption and security protocols such as SRTP, SIPS, TLS and HTTPS ensure secure transmission of telephony and configuration data. This allows you to make calls reliably and securely without having to worry about technical details.

Central phone book for a better overview

The IP phone set offers a central phone book with space for up to 300 entries. Each contact can contain multiple phone numbers and is available to all registered handsets. In addition, the handsets have their own local phone books. This allows you to keep track of your contacts at all times and access them quickly.

Flexibly expandable and ideal placement

The base station is connected to the router via a LAN cable and can be set up where DECT coverage is best. The handsets can be flexibly distributed throughout your home or workplace, for example in the kitchen, living room, bedroom or office.

The system is compatible with other Gigaset HX handsets and can be easily expanded as needed. This allows your telephone solution to grow with your requirements.

Cordless and energy-efficient: ECO DECT with the Gigaset BasicLine IP + COMFORT 500HX

Cordless phones offer everyday flexibility – and with ECO DECT, the Gigaset BasicLine IP + COMFORT 500HX also provides an energy-efficient and low-radiation solution. But what does ECO DECT mean in practice? In standby mode, the system is radiation-free – even when multiple handsets are registered, provided that the base station and all connected handsets support ECO DECT. During a call, the transmission power automatically adjusts to the distance between the base and the handset. This means: the closer the handset is to the base station, the lower the transmission power. To benefit from maximum DECT range, ECO DECT mode can be deactivated if required.
