What Auerswald does

Auerswald GmbH is a family-owned German manufacturer of IP-based business telecommunications systems, headquartered in Cremlingen, Lower Saxony, with a 65-year operating history dating to 1960. The company designs, develops, and produces its hardware and software exclusively in Germany and sells a '360-degree' portfolio: the COMtrexx cloud-capable PBX (available as hardware appliance or VM with licensing tiers Next, Flex, Business, and Advanced), the COMpact on-premises hybrid PBX family (supporting ISDN, analog, and VoIP), the COMuniq ONE cloud telephone system, the COMfortel D-series SIP desk phones and M-series DECT mobile handsets, the COMfortel SoftPhone 2 cross-platform softphone, IP-DECT multicell systems, door entry systems, proprietary SIP trunking, and the Auerproxy server for remote softphone provisioning. A separate Auerswald EMS business provides OEM electronics manufacturing from PCB assembly to complex end products using a worldwide network of 250+ distributors and lean assembly lines accepting batch size 1.

Auerswald serves primarily German small and medium-sized enterprises plus targeted verticals such as healthcare and senior care (e.g., the Stiemerling Senioren-Residenz deployment using COMtrexx with alarm messaging), with additional OEM clients served through the EMS unit. Revenue is generated across six streams: hardware sales, software licenses and subscriptions (including recurring COMuniq ONE cloud subscriptions and COMtrexx licensing tiers), SIP trunk services, OEM/EMS manufacturing, and professional services/training delivered through the Auerswald Academy.

Go-to-market is overwhelmingly indirect: products are sold through authorized specialist dealers (Fachhändler) searchable via an online dealer locator, supported by a Premium Partner program, an exclusive partner portal, and an in-house Auerswald Academy. Direct enterprise sales and an own e-commerce shop (shop.auerswald.de) supplement the channel for licenses, spare parts, and larger accounts. Operating geographies are primarily Germany with extension to Austria and Switzerland, and the company imposes written-authorization controls on non-EU shipments. Following insolvency proceedings resolved in December 2025, Auerswald continues to operate as an independent family business led by CEO Christian Auerswald.
