We build the software that runs under the carriers you’ve never heard us talk about.

▍ Scope · 01

Thirteen disciplines. Thirty-five repositories. One inbox.

vici.tel is a small engineering studio that designs and operates telecommunications and messaging applications for carrier services — wholesale voice, real-time observability and fraud detection, contact-center floors, AI agents on top of switches, number lifecycle, message delivery, and the reference data carriers run on.

Most of what we ship runs under another brand. We do not advertise the products and we do not have a sales team. Email is the fastest way to reach us — hello@vici.tel.

What we build

13 lines of work
01 Flagship
№ 01 Observability

Carrier observability and fraud detection.

A real-time NOC platform watching every CDR, SIP flow, and media stream a carrier network produces. Nine purpose-built detection engines surface false-answer supervision, audio-verified fraud, call-stretching, routing loops, traffic-pattern anomalies (CLI flooding, wangiri, TDoS), media-quality regressions against baselines, post-dial-delay drift, and SIP signaling shifts. Detections feed multi-brand ticketing with SLA enforcement, a vendor-and-client CRM, and AI-assisted email workflows.

Operating doctrine

Three rules · unrevised since day one
i.

The system has to keep working at three in the morning.

We design for the night shift — health endpoints, idempotent tasks, structured logs, replayable queues, and quiet failovers.
ii.

Every minute is a CDR somewhere.

We treat call-detail records, rate decks, and billing reconciliation as primary artifacts, not afterthoughts. Margins live or die in those files.
iii.

Pick technology that ages well.

Postgres, Kamailio, FreeSWITCH, Asterisk, RTPEngine, PJSIP, Django, Next.js, Go. The modern parts wrap stable cores; the stable cores outlive the modern parts.
