The customer calls first
A trunk silently degrades the ASR from 90% to 70%. Global thresholds never see it. The ticket arrives from the client, not from monitoring — with the SLA already expired.
SIP · SIPREC · HEP · 100% self-hosted
The agentic NOC for your voice network.
It does not just capture your calls. It watches them, investigates anomalies on its own, explains the root cause, and alerts your phone with action buttons. Acknowledge, resolve, investigate deeper, or approve a safe remediation. Every resolution makes the next diagnosis smarter.

The problem
Your client detects the fault before your NOC
Every minute it takes you to detect a voice quality problem is a minute your customer is already considering leaving.
2–4 hours per incident
Wireshark, grep in SBC, manual captures and correlation by hand. Each incident burns up senior engineer hours while traffic continues to fail.
Days waiting for the manufacturer
Without evidence of your own, the diagnosis ends in a ticket with the manufacturer of the SBC. Days of waiting, generic answers and zero control over the timeline.
Without knowing which carrier is failing
Carrier A or Carrier B? Destination or route? Without attribution by trunk and by country, conversations with suppliers are competing opinions, not evidence.
🤖 The authentic NOC
A virtual NOC engineer who runs the incident cycle from end to end
DETECT → INVESTIGATE → DIAGNOSIS → NOTIFY → ACT → LEARN
Actions are executed only after your approval — and the AI has no tools to change your network. By design, not by promise.
Incident engine
Each anomaly becomes a persistent incident with a lifecycle (open → recognized → resolved), deduplication, auditable timeline and self-resolution for stability. Dedicated Incident Tab with one-click actions.
Freelance researcher
As soon as you open an incident, VoxyWatch investigates on its own: sample failed calls, dominant SIP codes, failing IP routes, and whether other trunks were degraded as well — the local-vs-carrier signal. Using your LLM key, write down the probable root cause citing that evidence.
Telegram and mail with action buttons
Critical incidents arrive on your phone with the attached diagnosis and inline buttons: Recognize · Resolve · Investigate · plus proposed remediation when applicable. Each portal user links their own chat with a single-use code. Each action audited by real user, restricted by role.
Runbooks + case memory
Includes field runbooks that the researcher follows and cites step by step — add your own as JSON. Resolved incidents become institutional memory: “same as incident #123, resolved: carrier maintenance.”
Statistical confidence
CRITICAL must be earned: minimum sample, measurement coverage, deviation from the core's own baseline, sustained degradation. Validated with production data: −92% false critical noise.
Capacity and digest forecast
Audio retention is measured, not estimated — capacity incidents open before you run out of space. A daily/weekly digest arrives at Telegram or your webhook according to the calendar.
🛟 Secure remediation, with your approval
The proposed actions come from a closed catalog at the code level (restart the capture sniffer, recalculate baselines — never your SBC), are executed only after your tap, and remain in the timeline of the incident with who-approved-what.
Who it's for
Built for teams operating real voice networks
Carriers, ITSPs, UCaaS providers, and voice integrators. Vendor-agnostic, multi-SBC, self-hosted.
Carriers
A NOC view of every interconnect: ASR/NER by route, anomaly detection by trunk, and 5xx spikes flagged as they happen.
ITSPs
Visibility by customer, quality by destination, carrier attribution via ITU-T E.164, and audio evidence when you need to prove what happened in a call.
UCaaS providers
Auditable voice quality by tenant: MOS, jitter, packet loss, and PDD. Detect degradations before customers escalate.
Voice integrators and MSPs
Diagnose calls without escalating to the SBC vendor. Incident analysis with evidence across multiple platforms.
VoxyWatch
From a SIP packet to the action your NOC needs to execute
Capture, attribute, learn and explain — all in a single self-hosted binary.
Universal multi-source capture
Two ingestion paths: HEP v1/v2/v3 (tested with Asterisk, Kamailio, OpenSIPS, FreeSWITCH, RTPEngine, Sansay) and a native SIPREC recording server in beta (Oracle, Ribbon, AudioCodes, Cisco CUBE) — plus the included voxywatch-probe (Go + libpcap) for everything else.
Carrier and country intelligence
Load your trunks only once. Each call is attributed to its carrier by IP/CIDR and to its destination country via an ITU-T E.164 engine with longest match (197 codes). ONNET traffic marked separately.
Automatic baselines per trunk
Each trunk learns its own normal (mean ± σ per hour). Detects silent drifts that global thresholds miss — like a ASR dropping from 90% to 70% on a single carrier.
AI co-pilot for NOC — your own key
Co-pilot by trunk and summary: reads health + baseline + 48h trend, returns probable cause and action for NOC. Works with OpenAI, Anthropic, Gemini or OpenRouter. Never touch the SBC.
Embedded SNMP agent + traps
Integrated SNMP v2c/v3 agent with 30+ OIDs and traps per edge for capture loss, sniffer down, low ASR/MOS, disk/CPU/RAM pressure. Downloadable MIB. Integrates with PRTG, Zabbix, Nagios.
100% self-hosted, no exceptions
A single binary + PostgreSQL/TimescaleDB, provisioned by the installer in 60 seconds. Your hardware, your data, without cloud, without telemetry, without call-home.

🔒 PCI-DSS
Designed for PCI-DSS environments
When your customers dictate card numbers over the phone, the sensitive RTP is discarded at the source. The payment audio never leaves the secure environment, never travels over the network, never reaches VoxyWatch.
Maximum scope reduction
The Probe discards the RTP from the payment window at the source — the lowest possible PCI scope for your deployment.
Hot reload via JSON
Add or remove SSRCs in pci_suppress.json — Probe applies in seconds, no reboot, no maintenance window.
Defense in depth
Works with portal suppression for two-layer assurance: misconfigured Probe entries are detected on the server before storage.
CRM Ready
Your contact center system writes the SSRC when the agent activates pause. Resume removes it. No new infrastructure.
🔗 Server MCP
Your voice network, exposed to your agents
VoxyWatch includes a standalone Model Context Protocol server: connect Claude Desktop, Claude Code or any agent compatible with MCP and let it query health, KPIs, trunk status, CDRs and incidents — with evidence and diagnostics — through 6 read-only tools. Authenticated with the same scoped API keys.
voxywatch-mcp.js · 6 read-only tools · scoped API keysYour corporate AI can now interrogate your voice network.
HEP · SIPREC
Two intake routes cover practically the entire market
If your device speaks HEP or SIPREC — and almost everything does — VoxyWatch works with it.
HEP · tested
HEP — tested and supported
Validated in laboratory and production.
SIPREC · beta
SIPREC — native SRS (beta)
VoxyWatch includes a native SIPREC recording server (RFC 7865/7866). These SBCs send their recording session directly to VoxyWatch — without agent HEP. SIPREC support is in active beta; Write to us and we will validate it with you for your specific SBC.
Does your source emit neither HEP nor SIPREC? The voxywatch-probe (libpcap) captures it from the NIC. Step by step guide on the wiki.

use cases
Real use cases
From theory to diagnosis in minutes.
Debug a carrier interconnect
Filter by status = failed, open any call and the SIP diagram shows the INVITE → 100 → 486. Root cause confirmed in less than 5 minutes.
Audit recordings SIPREC
Reconstructs the audio, listens by channel, and traverses with jitter and RTCP to locate exactly where the client's audio was cut off.
Validate a new SBC
Make test calls and verify that they appear with correct numbers, high MOS and clean diagrams before going to production.
Who built it
Built by network engineers with real experience operating carrier-grade voice networks.
VoxyWatch is not a generic observability platform that SIP learned last quarter. It's designed by people who have operated voice networks — and built specifically for the engineers who do.
🔒 Early adopter pricing is locked in while we incorporate our first wave of customers.
FAQ
Frequently asked questions
What we get asked the most before we start.
How do I cancel my subscription?
Open the Paddle customer portal and cancel in one click — link below. Your license remains active until the end of the period.
Open Paddle portal →Do you accept bank transfer, PayPal or Stripe?
Yes, upon request. Write to [email protected] with the method and duration you prefer, and we will coordinate it.
Can I upgrade from Pro to Telco without losing what I already paid?
Yes. Open a support ticket and we will credit the unused portion of your Pro license towards the Telco plan.
What happens if my server breaks or I need to change hardware?
Open a support ticket. We reissue your license for the new HWID. Same plan, same expiration.
Do you issue an invoice for my accounting?
Yes. Open a support ticket with your tax information (company name, RFC/Tax ID, address) and we will send a formal invoice.
Can you bill me in MXN, EUR or another local currency?
Upon request. Open a support ticket with the currency and duration, and we coordinate outside of Paddle's default USD flow.
What happens when my license expires? Do I lose my data?
No. Your CDRs, audio recordings and settings remain intact on your server. Only new captures are paused until you refresh.
Does VoxyWatch send data to the cloud?
No. VoxyWatch is 100% self-hosted. Without telemetry, without call-home, no data leaves your network. The only way out is calls to the AI copilot — and those use YOUR API key, to YOUR chosen provider.
Is there a free trial period?
Yes. The Free tier (50 concurrent calls, unlimited CDRs) is free for life and includes all features. No card. You install in 60 seconds.
Can the AI agent change my network?
No. The AI does not have any tools to touch your SBC — by design, not by promise. The proposed remediations come from a closed catalog at the code level (restart the capture sniffer, recalculate baselines) and are executed only after explicit human approval, with full audit of who approved what.
How does the AI Copilot handle privacy?
It's bring-your-own-key. You configure your own API key of OpenAI, Anthropic, Gemini or OpenRouter. Requests go directly from your VoxyWatch to the provider you choose. VoxyWatch never sees the data and never passes through our servers.
