IP communication system Auerswald COMtrexx Next — VoIP gateway with G.711/G.722 codecs, T.30/T.38 fax support, multi-factor authentication, black

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. Organisations that need rack-mounted, highly modular hardware or extensive on-premise telephony expansions beyond the specified device and user limits should consider larger systems.

For mobile work, deploy the COMfortel SoftPhone 2 on users’ mobile devices and integrate it with the COMtrexx system.

What to consider before purchase

• Planned number of users and devices to ensure limits (max. 40 users, max. 200 devices) meet your needs
• Required simultaneous call capacity (up to 40 simultaneous calls)
• Need for fax over IP and supported codecs (G.711/G.722, T.30/T.38)
• Remote management requirements and compatibility with the COMtrexx Control Center
• Power availability and preference for a fanless, low-power device

Recommendations

For small offices and branch sites, license users in packages that match your growth (available packages up to 5/10/20/30/40 users), enable remote monitoring for centralised maintenance, and use the COMfortel SoftPhone 2 for mobile workplaces to maximise flexibility.
