In the ever-evolving landscape of telecom, security is no longer a technical afterthought. It is a business-critical function. Every second, voice and messaging data is transmitted, routed, and stored across complex infrastructures that are vulnerable to threats. As organizations migrate to cloud-based telecom systems, security challenges increase in both scope and sophistication.
That’s where Opentact shines. Beyond its well-known benefits as a robust Class 4 VoIP switch, PBX, media server, and API-powered telecom platform, Opentact also delivers next-gen telecom security in ways that are built-in, not bolted on.
Here are five telecom security features you might not realize are quietly protecting your communications on the Opentact platform:
⛔️ 1. SIP & Media Stream Encryption
Complete End-to-End Encryption with TLS & SRTP
Opentact supports TLS (Transport Layer Security) and SRTP (Secure Real-Time Transport Protocol) to encrypt both signaling and media streams. This ensures that:
SIP INVITE and REGISTER requests are hidden from prying eyes.
Audio packets can’t be intercepted or tampered with.
Your voice and video communications remain private, even over public internet links.
With Opentact, encryption isn’t optional—it’s embedded by default.
🛡️ 2. Real-Time Fraud Detection & Blocking
AI-Powered Pattern Recognition for Unusual Activity
Telecom fraud can cost businesses millions annually. Opentact actively scans your call activity for unusual behaviors such as:
Traffic spikes from unexpected regions
Sudden changes in call duration or frequency
Pattern-matching against known fraud profiles
When a suspicious activity is detected, Opentact takes action automatically: rate limiting, rerouting, or blocking calls before damage can escalate.
🧰 3. Isolated SIP Domains for Tenant Security
Custom Subdomain Segmentation for Each SIP Group
Opentact allows organizations to create multiple SIP domains, each with custom routing logic, SIP users, and access controls. This multi-tenant isolation approach ensures:
Each domain is protected from spillover risks.
SIP routing logic is sandboxed.
You can assign different policies and features per customer or department.
Perfect for resellers, partners, and enterprise clients needing isolated infrastructure.
📈 4. API-Level Access Control & Audit Logging
Full Session Control via Secure APIs
APIs are powerful, but they must be secure. Opentact's developer-centric API ecosystem is backed by:
Token-based authentication
Role-based permission models
Call detail logging and audit trails
You can programmatically create users, configure routing, and monitor usage—with full traceability for compliance and audits.
🧳 5. Secure Call Routing & Failover Logic
Dynamic Rules to Prevent Downtime and Intrusions
Using Opentact's smart routing engine, admins can:
Set call failover routes in case of endpoint failure
Dynamically reroute calls based on time, location, or traffic thresholds
Prevent toll fraud by whitelisting or blacklisting call destinations
These routing rules act like a firewall for your call flows, adding resilience and control.
