A network operations centre staffed by voice engineers
Our NOC runs 24 hours a day, 365 days a year across three follow-the-sun shifts. The person who answers a P1 call can read your SIP trace, check the route in the switch and make a change — there is no tier-one script and no queue to be escalated out of. Median first response on a P1 is four minutes.
Three ways in, depending on urgency
Use the right route and you skip triage entirely. All three are available to every customer regardless of plan.
NOC emergency line
For service-affecting faults only: trunks down, one-way audio across a site, mass call failure or suspected fraud. Answered live, day or night, by an engineer with switch access. Median first response four minutes.
Support email and portal
Portal ticketing included on every account
Configuration changes, quality investigations, interop questions, new trunks, number orders and API issues. Ticket raised automatically on receipt, first response within 30 minutes for P2 and four hours for P3.
Account and billing
Invoices, rate queries, CDR reconciliation, contract changes, service credit claims and adding capacity. Monday to Friday, 08:00–20:00 in your local time zone, with a response inside one business day.
How we classify and respond
Severity is set by business impact, not by who is asking. If you believe a ticket is under-classified, say so and we will re-grade it without argument.
| Severity | First response | Definition |
|---|---|---|
| P1 — Critical | 4 minutes | Total loss of service on a trunk group or site, mass call failure, emergency calling unavailable, or suspected toll fraud in progress. Worked continuously until service is restored, with 30-minute updates. |
| P2 — Major | 30 minutes | Service is up but materially degraded: audio quality below acceptable MOS, elevated call failure on specific destinations, failover not behaving as designed, or a single site down while others are healthy. |
| P3 — Minor | 4 hours | Individual user or extension affected, non-urgent configuration change, number order, routing adjustment, portal or reporting anomaly with a workaround available. |
| P4 — Request | 1 business day | Questions, documentation requests, interop guidance, feature enquiries, scheduled work with no time pressure and planning support for upcoming migrations. |
Response targets apply to every customer on every plan. Restoration times vary by fault and are tracked individually in each incident review.
What the 99.999% commitment actually means
Availability is measured per calendar month, per trunk group, from our own SBC and media telemetry rather than from an external ping test. 99.999% allows roughly 26 seconds of unavailability in a 30-day month.
Unavailability starts at the first failed call attempt recorded against a healthy configuration and stops when calls complete normally again. Because trunks are anchored in a primary PoP with a hot standby in a second region, most PoP-level events re-anchor sessions in under 400 milliseconds and never register as downtime at all.
Excluded from the calculation: scheduled maintenance announced with the required notice, faults on your LAN, PBX, firewall or internet circuits, force majeure events, and outages caused by configuration you changed without a change record. Everything else counts, including our own failed deployments.
- Measured monthly per trunk group, published in your portal alongside MOS and ASR
- Availability data retained for 24 months and exportable for your own audit
- Written root cause analysis for every P1 within five business days, whether or not you ask
- Custom SLAs with additional financial remedies available on enterprise agreements
Service credit tiers
Credit is calculated against the monthly recurring charge for the affected trunk group.
Claiming a credit
- Email support@telecorenetwork.com within 30 days of the month end, quoting the affected trunk group
- Reference the incident ticket numbers, or ask us to identify them from the availability report
- We verify against platform telemetry and confirm in writing within five business days
- Approved credits appear on the next invoice — no cheque process, no negotiation
Credits are the contractual remedy for missed availability. Tiers shown are the standard published terms; enterprise agreements may specify different thresholds.
Self-service before you need us
Most of what our engineers know is written down. These are the resources customers open most often.
SIP interoperability guides
Tested configurations for 60+ PBX and SBC platforms including Asterisk, FreeSWITCH, 3CX, Avaya Aura, Cisco CUCM, Mitel MiVoice and Genesys, with version-specific notes.
API reference and SDKs
REST endpoints for call control, number provisioning, recording and CDR retrieval, webhook payload schemas, sandbox credentials and SDKs for Node, Python, Java, Go, PHP and .NET.
Number porting handbook
What a CSR must contain, common rejection reasons by market, realistic timelines per country, batching strategy for large ranges and how cutover windows are scheduled.
Live status page
Per-region and per-service health, current and historical incidents, scheduled maintenance calendar, and email, SMS or webhook subscriptions you configure yourself.
Device provisioning
Zero-touch provisioning profiles for Yealink, Poly, Cisco, Snom and Grandstream handsets, plus firmware policy, DHCP option 66 setup and softphone deployment notes.
Security whitepaper
Encryption model, fraud detection thresholds, data residency options, retention schedules, sub-processor list and our SOC 2 Type II scope. Full report available under NDA.
How new customers get up to speed
Every account runs the same four-stage onboarding, whether it is 10 channels or 5,000.
Kick-off and design review
Within two business days of signature you meet your named engineer, walk through sites, PBXs, number ranges and peak concurrency, and receive a written design with a dated migration plan.
Sandbox and interop testing
You get a test trunk, 500 free minutes and API sandbox keys. Our interop lab validates your platform version and publishes a configuration guide specific to it before anything touches production.
Admin and NOC training
Two live sessions, recorded for your own library: portal administration, routing and failover configuration, reporting and CDR export; then escalation paths, severity grading and how to open a P1 correctly.
Go-live and 30-day review
Your engineer is on the bridge for cutover and stays reachable for two weeks. At day 30 we review measured MOS, ASR, concurrency and spend, and tune routing and capacity against real traffic.
Support questions, answered plainly
The things customers ask in their first month, and the things they wish they had asked before signing.
Everything on our side of the demarcation point: trunks and SBCs, routing and carrier selection, number provisioning and porting, the portal and API, billing accuracy, and call quality across our network. If a call is degraded anywhere between our edge and the terminating operator, that is ours to fix.
We also help with the part that is technically yours. Our engineers will read your SIP traces, check codec and DTMF negotiation, review your QoS marking and tell you plainly when the fault is in your LAN, firewall or PBX. We will not close the ticket the moment we can prove it is not our network — we would rather help you find it than win the argument.
Two routes, both immediate. Reply to the ticket with ESCALATE in the subject line, or call the NOC on +1 (800) 555-0111 and quote the ticket reference. Either action raises the severity by one level and pages the on-duty shift lead straight away — it does not put you into another queue.
P1 tickets also escalate on their own. If service is not restored within 30 minutes the duty manager joins, and at 90 minutes the VP of Network Operations is paged and takes ownership of communication. Enterprise accounts additionally have a named engineer and their direct number, so escalation does not depend on the general line at all.
Standard maintenance runs Tuesday to Thursday between 02:00 and 05:00 in the local time zone of the affected PoP, and you receive at least ten calendar days' notice by email and portal notification. Because trunks are anchored across two regions, the overwhelming majority of maintenance is performed with sessions drained to the standby PoP and no customer impact at all.
Emergency maintenance — an active security fix or an imminent hardware failure — can proceed with as little as one hour's notice, but it is always announced before work begins and never applied silently. Enterprise customers can nominate blackout periods such as quarter-end or a peak trading week, and we will schedule around them.
Through the status page, which you control. Subscribe as many email addresses, SMS numbers and webhook endpoints as you need, and filter by region and by service so your network team is not paged about an SMS issue in a market you do not operate in.
During a P1 we publish an initial notice within 15 minutes of declaring the incident, update at least every 30 minutes until resolution, and follow up with a written root cause analysis within five business days. That RCA states what failed, what customer impact was measured and what we have changed to prevent a recurrence — it is sent whether or not anyone asks for it.
Yes, and porting standard geographic and toll-free ranges is included at no charge. A porting coordinator is assigned to your project: they validate your customer service records before submission, submit and track each order, chase rejections with the losing carrier and book cutover windows with you rather than around you.
Ports are run as parallel migrations. Your new trunks are live and tested before any number moves, and large estates are ported in scheduled batches so a single problematic range cannot hold up the whole project. Typical timelines are 7–15 business days in North America and 2–6 weeks internationally, and the handbook lists realistic expectations per market.
We do not administer your PBX or contact centre application, we do not manage your LAN, firewall, SD-WAN or internet circuits, and we do not provide desktop support for handsets we did not supply. Custom development against our API is your work; we will review your integration and answer questions, but we will not write and maintain your application.
For the SLA specifically, outages caused by your own undocumented configuration changes, third-party equipment failure, ISP outages or force majeure do not accrue service credits. That said, exclusion from the SLA is not exclusion from help — our engineers will still work the ticket with you until the cause is identified.
The NOC is staffed right now
If service is affected, call the emergency line and you will speak to an engineer with switch access. For anything else, open a ticket and you will get a written answer inside the response target for its severity.
