VoIP / SIP Gateway

The ABC WebRTC Gateway is a software-based solution that can be used as a standalone solution. The ABC WebRTC Gateway offers all the functions of the ABC SBC and easily connects WebRTC clients with each other.


VoIP Security

Secure the Border of your VoIP Network


Rate Limiting

Limit the number of parallel calls and call attempts as well as the bandwidth used by the media streams.


Content Control

Filter the content of incoming SIP messages and drop messages that contain suspicious content.


Topology Hiding

Hide all information related to the VoIP internal structure such as IP addresses of media servers or SIP registrars.


Media Control

Reject media packets that do not conform to the type that was signaled in the session establishment.

VoIP Realtime-Monitoring 

With the ABC Monitor and the Zero Trust Monitor, FRAFOS offers companies, service providers and authorities reliable tools for preventing quality problems and gaining a complete overview of call statistics, error cases and anomalies.

Real-time Look at Your Network


The ABC Monitor provides administrators with an interactive view of user activity based on real-time usage report data collected from the ABC SBC / WebRTC gateways, including trend analysis, analysis of short and long-term usage patterns, troubleshooting, server policy review and identification of abusive usage.


The ABC Monitor provides the operator of the ABC SBC and the ABC WebRTC gateway with a comprehensive overview of the performance of the VoIP infrastructure and alerts them in the event of failures.

Zero Trust VoIP Security Monitor

Zero Trust VoIP Security Monitor_Mockup.png

The Zero Trust Monitor solves the dilemma between user privacy and VoIP monitoring of usage behavior in the network by encrypting the data for the analysis and processing steps during the collection process.


Administrators and operators thus receive encrypted analyses, but have the necessary tools at hand to ensure optimum protection of the network.

The FRAFOS solution provides the following advantages:


Non-disruptive Integration

Even though the solution is based on WebRTC, the call centre itself does not have to support WebRTC.


Cloud Ready

The FRAFOS components are provided as a software solution that can be used on dedicated hardware, installed in a hosted system or run over a cloud technology such as Amazon or openstack.

Cloud or hardware: Your choice

Whether already on the cloud or planning to move to it, the ABC platform was designed to function in all environments. The ABC platform is provided as software solution that can be deployed on off the shelf hardware, VM, container or cloud environment.
