Carrier Voice / SMS B2O

For 25+ years, we have delivered high-quality voice termination and A2P SMS for carriers and service providers. Our wholesale platform offers stable routing, competitive rates, fraud protection, and real-time analytics across Greece and international destinations.

We operate with carrier-grade infrastructure and long-term interconnections, providing CLI preservation, DLR for messaging, and transparent billing. Interconnect is trusted by national providers of Greece and 400+ telecom partners worldwide.

Working challenge

The cybersecurity field can be broken down into several different sections, the coordination of which within the organization is crucial to the success of a cybersecurity program. These sections include the following:

  • Volatile ASR/ACD and low quality due to unstable routes.
  • Grey routing, spoofed CLI, and toll-fraud exposure.
  • No real-time visibility into KPIs, QOS, and spend.
  • Complex number portability (MNP) and inconsistent CLI presentation.
  • Incomplete DLR and filtering problems on A2P SMS.
  • Opaque rating and unpredictable costs at scale.
  • Limited NOC responsiveness and weak incident process.

Benefits with our service

We serve the best work

We combine operator-class interconnects with strict quality and anti-fraud controls.
Lifecycle: AssessInterconnectTestLaunchOptimize.

  • Voice: CLI/CLI-restricted, premium and standard A-Z, quality tiers, LCR with KPI thresholds and automatic fallbacks.

  • SMS A2P: DLR-backed routes, sender ID policies, throughput control, content filtering compliance, campaign testing.

  • Operations: real-time monitoring, anomaly detection (ASR/PDD/MOS), spend caps, incident runbooks and RCA reports.

Typical outcomes: stable ASR/ACD uplift, lower PDD, fewer disputes, predictable margin with transparent routing policy.

Questions about service

We operate with KPI-based routing and targets around ASR, ACD/ALOC, PDD, MOS by destination and tier, reported monthly.

Yes. We maintain CLI where applicable and implement anti-spoofing and test-call routines to detect grey routes.

We use real-time MNP databases and HLR-like checks to ensure correct routing and billing by current network.
