Enterprise VoIP Solutions Built for Modern Business Communication
Telecorenetwork runs a privately operated voice backbone across 42 points of presence, delivering SIP trunking, hosted PBX, DID numbers and programmable communications with carrier-grade reliability — and none of the legacy complexity.
Interoperable with the platforms enterprises already run
One communications layer for every part of your organisation
Most enterprises end up with a patchwork: a legacy PBX in headquarters, a regional carrier for each subsidiary, a separate CPaaS vendor for notifications, and a contact centre that talks to none of it. Telecorenetwork replaces that with a single interconnect, one contract and one portal.
- Consolidate voice, messaging and contact centre onto one platform and one invoice
- Port existing numbers with zero downtime using parallel-run cutover
- Keep the handsets, PBXs and CRMs you already own — we interoperate, not replace
- Scale channels on demand instead of buying PRI circuits 23 channels at a time

Explore SMSSix reasons enterprises move their voice to us
We are not a reseller with a dashboard. We own the switching layer, the routing logic and the escalation path.
We own the network
Our own softswitch fabric, session border controllers and direct carrier interconnects. When something needs fixing, we fix it — we don't open a ticket with a wholesaler and wait.
Audible quality, measured
Every call is scored for MOS, jitter and packet loss. Routes that drift below threshold are automatically demoted before your users notice a thing.
Humans on shift, always
A 24/7/365 NOC staffed by voice engineers, not a call-deflection bot. Median first response of 4 minutes on P1 incidents, with a named escalation contact.
Pricing you can audit
Published per-destination rates, no minimum spend traps, no ambiguous "regulatory recovery" line items. Your CDRs reconcile to the cent.
Security as default
TLS 1.3 signalling and SRTP media on every trunk, fraud velocity controls enabled from day one, and full STIR/SHAKEN attestation on US traffic.
Built for engineers
Every portal action has an API equivalent. Terraform provider, webhooks, streamed CDRs and a full sandbox so you can test before you commit.
42 points of presence. One routing brain.
Media stays close to your users. Signalling anchors at the nearest PoP, media transcodes at the edge, and traffic only crosses an ocean when the destination genuinely lives there. That is why our median edge latency sits at 18 milliseconds instead of 90.
Voice is an attack surface. We treat it like one.
Toll fraud, caller-ID spoofing and eavesdropping are not theoretical risks — they are the three most common voice incidents we remediate for new customers in their first month. Our controls are on by default, not sold as an upgrade.
Encrypted end to end
TLS 1.3 for SIP signalling, SRTP with AES-256 for media, on every trunk at no extra cost.
Fraud velocity guards
Per-trunk spend caps, destination allow-lists and anomaly alerts that trigger in under 60 seconds.
STIR/SHAKEN attestation
Full A-level attestation on US-originated traffic so your legitimate calls stop getting flagged.
Data residency control
Pin recordings, CDRs and metadata to EU, US, UK or APAC storage regions to satisfy your regulator.

What changes after the cutover
Representative results from enterprises that consolidated their voice estate onto Telecorenetwork.
We retired 46 PRI circuits across nine sites in eleven weeks. The parallel-run cutover meant not a single customer-facing line dropped, and our monthly voice spend fell by roughly a third.
The API is the reason we chose them. Our engineers provisioned 3,400 DIDs across fourteen countries with a Terraform plan. No spreadsheets emailed to an account manager.
Our contact centre handles 40,000 calls a week. Since moving, abandonment is down 22% purely because connection times improved and the routing finally respects agent skills.
