COMfortel® SoftPhone

Softphone and messaging solution with mobile and secure connection to COMtrexx and COMpact ICT systems

Inexpensive soft client for SIP voice and messaging

Secure and easy PBX connection from anywhere via free cloud service

Cross-platform: Apps for Windows, iOS & Android

Your advantages in detail

COMfortel SoftPhone optimizes the availability of employees in a simple yet secure way. The soft client for telephony and internal company chat is available for Windows, iOS and Android.

The secure and location-independent connection to your COMpact ICT system is guaranteed by an innovative Auerswald cloud service, which makes the complex and maintenance-intensive connection via VPN superfluous.

COMfortel SoftPhone is the cost-effective alternative to the comprehensive Unified Communication and Collaboration (UCC) solution PBX Call Assist. Whenever integration into business processes, video conferencing or file and desktop sharing is not required, COMfortel SoftPhone is a good investment for COMpact users , which pays for itself within a very short time.

COMtrexx users can also benefit from the advantages of the COMfortel SoftPhone. In the first 12 months, the use of the COMtrexx is free of charge. Afterwards, a low-cost licensing via the specialist dealer is required.
