A-Z voice termination

Routes for every destination — your way

Premium routes

Direct, CLI-guaranteed termination

Tier-1 direct interconnections straight to the destination network, bypassing transit operators — for the highest ASR and call quality on the routes that matter most.

Cost-optimized

Smart least-cost routing

Balanced least-cost routing (LCR) for price-sensitive traffic, with CLI and non-CLI options per stream — quality and economics tuned to every destination.

Quality, monitored

Quality you can measure — not just claim

Live route metrics

ASR, ACD, PDD, MOS and disconnect codes tracked continuously on every route.

Anomaly detection

Machine-learning models flag ASR/ACD drops, new or decreased traffic and routing loops the moment they appear.

Continuous route testing

Automated test calls verify CLI, FAS, PDD and MOS — no manual listening required.

Real-time alerts

Subscribe to the events that matter and get notified the instant a route degrades.

CDR & signaling traces

Tens of millions of records a day, stored and searchable in seconds for fast investigation.

ML quality review

Self-learning systems score route quality around the clock — not just on spot checks.

Fraud protection

Fraud protection built into the network

Threats we detect

SIM-box, PBX and network hacking, IRSF, Wangiri, CLI-spoofing, routing loops, and false answer supervision in all its forms — classic, smart/adaptive, delayed disconnect, fake ringback and media injection.

Detect and alert, 24/7

Live traffic is watched around the clock; ML models flag abnormal patterns and revenue leakage in real time.

Full signaling storage

Every call's signaling and traces are retained for the fastest investigation and dispute resolution.

Interconnect

Standards-based interconnect

Signaling

SIP and TDM interconnects, ISUP transparency, DTMF and T.38 fax.

Codecs

G.711 and G.729, with HD voice on supported routes.

Security

SRTP and TLS encryption, with IP access control on every interconnect.
