VoIP, SBC & SIP Trunking

Voice interconnection, mastered end to end.

SBC, carrier SIP trunks and unified communications: we design voice architectures that hold under load, resist attacks and respect your budget.

VoIP Engineering, SBC & Carrier-Grade SIP Trunking

A poorly architected voice interconnection means jitter, dropped calls, five-figure telecom fraud bills, and teams reverting to GSM. Voice over IP is an engineering discipline, not a checkbox.

Certified unified-communications engineers, with recognized expertise in carrier SIP Trunk deployment.

Session Border Controller (SBC)

Sizing, deployment and hardening of edge SBCs: topology hiding, TLS/SRTP encryption, voice fraud and DDoS protection, SIP flow normalization and transcoding.

Carrier SIP trunking

Interconnection with national and international carriers, channel sizing, numbering plans, least-cost routing, multi-carrier redundancy.

Core voice engineering

Carrier-grade architectures, end-to-end QoS management, perceived quality monitoring (MOS, jitter, packet loss).

Enterprise IP telephony

On-premise or cloud IPBX, migration from legacy systems with zero service interruption, fixed-mobile convergence.

Unified communications

Presence, instant messaging, video conferencing, Microsoft Teams and Google Workspace integration.

Contact centers

IVR, call queues, legal recording, real-time monitoring, CRM integration.

What you gain

In practice

Optimized interconnection costs
Telecom fraud blocked at the edge
Quality measured continuously, not assumed
Site-by-site scalability without a redesign
