● Production voice infrastructure · senior engineers

Stop dropped calls, dialer crashes, and carrier waste before they hit revenue.

Asterisk · VICIdial · FreePBX · SIP. In 48 hours, we isolate the voice-stack issues costing you uptime, margin, and agent time — plus Legacy-to-AI modernization. Fixes in hours, not tickets.

What we do for high-volume voice

Productized engagements. Pricing anchors below — final scope on a short call.

48-Hour Voice Stack Review

from $2,500

In 48 hours we find where your dialer loses uptime, margin, call quality or scale.

▹Read-only review of Asterisk/VICIdial/FreePBX, trunks, dialplans, queues, IVR, logs
▹CPS/concurrency capacity + AMD/ASR, answer-rate & carrier waste analysis
▹Risk map + prioritized action plan

Fee credited toward implementation. If we can't find ≥3 concrete fixes, it's free.

Critical Voice Stabilization Sprint

from $8,000

We stabilize the legacy voice stack your revenue depends on — without forcing a migration.

▹Root-cause fixes: crashes, dead air, phantom audio, dropped calls, trunk saturation
▹Hardening, backups, rollback, SIP routing cleanup, carrier failover, CPS tuning
▹Documentation + operator handoff

Most chosen

Managed Critical Voice Stack

from $5,000/mo

Senior Asterisk/VICIdial operators on retainer — your dialer stops depending on one person or slow tickets.

▹Monitoring, alerting, health checks, backup verification, incident response
▹Controlled changes: dialplan, carriers, caller ID, queues/IVR, rollback
▹Monthly review: uptime, dropped calls, cost leaks + roadmap

Legacy-to-AI Voice Modernization

from $12,000

We add AI to your existing voice operation — without replacing the core that runs your business.

▹AI call summaries, dispositions, classification, follow-up triggers
▹CRM/reporting integration; AI alerts for failed transfers, hot leads, risk
▹Optional AI voice agent for first-touch / after-hours

If this is your operation, we should talk

Dialer instability

Crashes under load, dead air, phantom audio at 200+ CPS.

Carrier & CPS bottlenecks

Trunk saturation capping concurrency and answer rates.

AMD / pacing waste

Paying for calls that never reach a human.

Undocumented dialplans

A critical system nobody wants to touch.

Slow vendor tickets

Weeks for changes that should take hours.

No AI layer

Manual QA, manual reporting, no automation.

Representative work (anonymized)

VICIdial + Asterisk · 300+ seats

Problem: nightly crashes at ~200 CPS, phantom audio.
Fix: CPS/trunk config, AMD re-tune, SIP failover, monitoring.
Result: stable 300+ CPS, ~18% fewer dropped calls, 9 days — no migration.

Cross-border BPO · MX↔CA

Problem: DNC + area-code compliance without losing throughput.
Fix: dialplan rules, automated scrubbing, audit logs.
Result: passed review, kept dialing, zero manual list-checks.

Contact center · AI layer

Problem: stable legacy stack, no AI, manual QA.
Fix: AI voice agent (LLM + speech) over Asterisk for first-touch.
Result: 24/7 first-touch, agents on qualified calls only.

Best fit if you…

▹Run 500+ calls/day on Asterisk, VICIdial or FreePBX
▹Depend on outbound voice for revenue (BPO, lead-gen, collections, insurance, solar, appointment setting)
▹Need senior help fast — and continuity beyond one internal person

Compliance-aware by design

Technical controls for DNC/opt-out, caller-ID & area-code routing, audit logs, and campaign safeguards. (Implementation — not legal advice.)

Production outage? Same-day triage for qualified stacks.
