Question 1

What is Hosted PBX security, and why is it important in 2026?

Accepted Answer

Hosted PBX security ensures that all voice, video, and messaging traffic in cloud-based phone systems is protected from unauthorized access, interception, and fraud. As cyber threats evolve, enterprises must adopt encryption, SBCs, firewalls, and predictive analytics to maintain secure communications.

Question 2

How can encryption safeguard voice and video traffic in Hosted PBX?

Accepted Answer

End-to-end encryption, utilizing protocols such as TLS for signaling and SRTP for media, ensures that calls remain unreadable if intercepted. Combined with SBC validation and continuous monitoring, encryption preserves confidentiality, integrity, and compliance without disrupting user workflows.

Question 3

What role do SBCs play in securing multi-tenant Hosted PBX systems?

Accepted Answer

Session Border Controllers (SBCs) act as gatekeepers, enforcing tenant-specific routing, authentication, and policy compliance. Custom VoIP SBC development enables secure isolation for each client, preventing cross-tenant data exposure and enhancing overall Hosted PBX security.

Question 4

How does predictive analytics strengthen Hosted PBX security?

Accepted Answer

Predictive analytics identifies unusual call patterns, assigns dynamic risk scores, and triggers automated alerts to address potential issues. By integrating with SBCs and firewalls, it proactively mitigates fraud, unauthorized access, and other security threats before they impact communications.

Question 5

What steps should enterprises take to future-proof Hosted PBX security?

Accepted Answer

Future-proofing requires a multi-layered approach: continuous monitoring, AI-driven threat response, ongoing encryption updates, predictive risk analysis, and scalable SBC and firewall architecture. This ensures resilience against evolving threats while maintaining seamless communication for users.
