The Distybox 300 is specially designed for households and smaller offices and can be easily personalised using an analogue telephone. The device has an integrated antenna and has a standard DECT range of up to 30 metres indoors and 300 metres outdoors.

4. Gigaset Repeater HX

More range for DECT phones
The new Gigaset Repeater HX doubles the DECT range of Gigaset base stations, enabling uninterrupted calls in perfect sound quality across multiple floors and spacious areas.

Prepared for the future
The additional implementation of the CAT-iq standard, as seen in all Gigaset HX universal handsets, ensures compatibility with DECT/CAT-iq routers that support the new ETSI Repeater Standard (ETS300700 V2.1.1). This makes the Gigaset Repeater HX ready for future generations of routers.

Features for enhanced security
With the new Early Encryption feature, encryption occurs before each call is transmitted. This ensures a particularly high security standard for telephony at work or at home. The Re-Keying function—changing the session key or encryption key during an ongoing communication—also enhances data security. The Gigaset Repeater HX continuously modulates the security key even during a call. Additionally, the device supports software updates via over-the-air interface (SUOTA). Thanks to these technologies, the Gigaset Repeater HX meets the current standards of the European Telecommunications Institute.

9. Auerswald 2-port ATA (analogue terminal adapter)

Standalone VoIP-Analog-Adapter with 2 ports. 1x GBit WAN and 1x GBit LAN port with NAT functions. Supports various audio codecs and fax modes.

The Flyingvoice FTA5102E2 VoIP-Analog-Adapter is designed to operate two analog devices (telephone, fax, intercom, etc.) on a VoIP connection. It does not matter whether the adapter is directly connected with the SIP credentials from the telephone provider or the login details of an extension from a VoIP-capable telephone system. Both analog ports can be configured independently.

The FTA5102E2 has been tested, and a basic configuration for operation with a COMtrexx has been created. This basic configuration is automatically downloaded upon startup and activated after a reboot. Only the access data needs to be entered. An unrestricted internet access is required for standalone configuration. When operating with a PBX, attention must be paid to port forwarding and prioritization of voice packets in the local network.

In addition to voice codecs, the following fax standards are supported: T.38, T.30, and G.711. 

10. Yealink Repeater RT30

Yealink DECT Repeater RT30. DECT Repeater. Compatible with Yealink W60B, W70B, and W52 DECT IP base stations. Up to 6 repeaters per base station (star configuration), up to 2 repeaters can be arranged in a cascade. Plug & Play setup. Clear LED status indicator. Elegant design, wall mounting possible.

The Yealink DECT Repeater RT30 is designed according to the Digital Enhanced Cordless Telecommunications (DECT) standard and features easy installation and a user-friendly display concept. The repeater can be used to significantly extend the DECT radio coverage of the Yealink W60B and W70B base stations in all directions. When working with the W60B or W70B, it supports two cascaded RT30 units. Clear LED indicators are used to distinguish various DECT statuses.

Additionally, the elegant design and straightforward installation make it particularly suitable for use in modern business environments. The device operates with DECT technology: utilize the wireless connection and move up to 50 meters away from the base station while talking indoors. Since the technology operates below 2.45 GHz, it uses different frequency ranges than Wi-Fi or Bluetooth, ensuring it does not interfere with these networks. Switching the base station within a multi-cell radio network is possible by forwarding to another cell.
