VoIP & Call Analytics — Signature Capability

Telephony as a Measurable Channel

VoIP and telephony engineering — SIP optimization, real-time CDR analytics, AI-driven call QA and compliance, predictive lead scoring on call data, cost-per-call intelligence. The signal hiding in every call is finally readable.

// Overview

The Approach

Telephony is where most operations leak value silently. A broker, a contact center, an inside-sales floor — every one is sitting on a stream of call data that, in principle, should be the cleanest performance signal in the business. In practice it sits in the PBX, in a CDR file nobody reads, in a dashboard that hasn't been opened since onboarding. The result is teams managed by gut feel on the one channel where the data is most measurable.

I close that gap from the SIP layer up. Trunks tuned for latency, jitter, and MOS the way a network engineer tunes a production link — because that is what they are. CDR streams piped into purpose-built analytics, not generic BI. ASR, ACD, agent-talktime, queue health, cost-per-call surfaced in dashboards leadership opens daily. AI sits on top: every conversation transcribed, scored against QA and compliance rubrics, and the ones that need human attention flagged within minutes of hang-up.

Then the loop closes. Predictive scoring on the call corpus tells the dialer which leads to surface first. Compliance flags route into the right inbox before the regulator gets there. Carrier cost is renegotiated against real per-route economics rather than rate-card fiction. Telephony stops being an overhead line on the P&L. It becomes the most accountable channel the business runs.

This is the signature engagement. The brokers and contact centers I work with measure the lift in two places that matter — ASR and conversion — and both move materially within the first quarter.

// What's Included

Capabilities In Scope

  • SIP & Telephony Engineering

    Trunking, routing, codec choice, NAT traversal, and the per-route tuning that makes voice quality a non-event across countries.

  • Real-Time CDR Ingestion

    Streaming call-detail records into a warehouse the moment the call ends — no nightly batches, no stale dashboards.

  • ASR / ACD / Agent Dashboards

    Answer-seizure ratio, average call duration, queue health, agent talk time — the metrics that drive an inside-sales floor.

  • AI Call QA & Compliance

    Every call transcribed and scored against the QA rubric and compliance ruleset. Flags surface within minutes — not next week.

  • Predictive Lead Scoring

    Models trained on call + CRM data rank leads by genuine conversion likelihood — the dialer surfaces the leads worth a human call.

  • Fraud & Toll-Abuse Detection

    Anomalies on traffic patterns, destinations, and identity flagged before a carrier bill reaches the board.

  • Cost-per-Call Intelligence

    Per-route, per-queue, per-campaign economics — so carrier negotiation is decided, not discovered at renewal.

  • Squaretalk & CRM Wiring

    Squaretalk, EspoCRM, click-to-dial, screen-pop, post-call workflows — the integration glue that makes the rest measurable.

// VoIP Intelligence Pipeline

From Dial Tone to Decision

Every call enters as raw signal and exits as structured intelligence — without a human in the loop until one is genuinely needed.

  1. 01

    Call

    SIP traffic answered, recorded, and tagged with route, queue, and agent metadata.

  2. 02

    CDR Capture

    Streaming call-detail records into the warehouse the moment the call ends — no nightly batches.

  3. 03

    Analytics

    ASR, ACD, queue health, cost-per-call surfaced in dashboards leadership opens daily.

  4. 04

    AI Scoring & QA

    Transcription, compliance rubric, QA scoring, and lead-intent classification within minutes of hang-up.

  5. 05

    Dashboard & Loop

    Decisions surface in BI; predictive scores feed back into the dialer queue. The loop closes.

// Process

Engagement Roadmap

  1. 01

    Trunk & Topology Audit

    Inventory every trunk, route, codec choice, dialplan, and PBX. Establish baseline ASR, MOS, jitter, and per-route economics.

  2. 02

    SIP Tuning & Routing

    Re-tune routing, codecs, and trunk failover for measurable lift in voice quality and answer rates. Cleanup pays for the rest of the engagement.

  3. 03

    CDR Pipeline Build

    Streaming ingestion, schema design, warehouse modelling, and the BI surfaces leadership will actually open every morning.

  4. 04

    AI QA & Scoring Layer

    Transcription pipeline, QA rubric, compliance ruleset, scoring model, and the human-review queue that makes the output trustworthy.

  5. 05

    Predictive Models

    Lead scoring trained against real call+CRM outcomes. Dialer integration, A/B framework, and the lift measurement that closes the loop.

  6. 06

    Operate & Optimize

    Continuous tuning — trunks, models, dashboards, cost. The platform compounds quarter over quarter.

// Outcomes
