VoIP call metrics (ASR, ACD, CPS)

Provides key performance indicators for VoIP calls, such as Answer-Seizure Ratio (ASR), Average Call Duration (ACD), and Calls Per Second (CPS), offering insights into communication efficiency and network performance.

Traffic prioritization

Allows for critical communications to be given precedence over less urgent traffic, ensuring that essential messages and calls are delivered without delay, even in congested network conditions.

Security & Reliability

End-to-End Encryption for voice, video and messaging

Ensures that all voice, video, and text communications are fully encrypted from the sender to the receiver, guaranteeing the highest level of privacy and security against unauthorized access.

Service redundancy and load balancing

Provides built-in safeguards with redundant services and intelligent load distribution across the system. This minimizes the risk of service interruptions and optimizes performance by efficiently managing network traffic.

High availability and real-time

Guarantees an industry-leading 99.999% uptime, ensuring that the system is almost continuously operational and communications are delivered in real-time, even during peak demand or unexpected events.

Automated backup and recovery

Implements automatic processes for data backup and system recovery, protecting against data loss and enabling swift restoration of services in the event of a system failure.

Operational Efficiency

Full API support – manage the system programmatically and seamlessly integrate with third-party solutions
