Auerswald COMtrexx Next is an IP communication (VoIP) system designed for enterprise telephony. It supports G.711 and G.722 voice codecs, T.30 and T.38 fax compatibility, and multi-factor authentication for secure access.

## Long description

The Auerswald COMtrexx Next is a compact All-IP communication system designed for small to medium business telephony. It provides a soft PBX in a miniature appliance with passive cooling and low energy consumption of well under 10 watts. The unit supports common VoIP voice codecs and fax standards, secure access options, and is supplied in black, making it suitable for office voice and fax integration where space and power efficiency are priorities.
Advantages
The device combines a full-featured soft PBX with a very small footprint and silent operation thanks to passive cooling. It supports up to 40 licensed users and up to 200 registered devices (up to 5 devices per user), offers modern user interfaces and comfort features such as CTI, MWI and BLF, and includes integrated conferencing and roaming user capabilities. The system is energy-efficient and designed for remote monitoring and configuration.
Suitable for
Small offices and branch locations that need a compact VoIP PBX
Workplaces requiring silent, low-power equipment
Teams needing up to 40 users and multiple devices per user
Environments that use voice and fax integration over IP
Installations where remote monitoring and centralized caller lists are useful
When it may not be suitable
It may not be the right choice for larger enterprises that require more than 40 licensed users or more than 40 simultaneous calls.
