Dare to Be Different.
We're built different.
High-performance VoIP that scales with you.
Reseller-tier SIP trunking, hosted seats, DID provisioning, call recording, and a white-label mobile app — all on Giant's VoiceCloud platform. Multi-tenant by design, geo-redundant SBCs, TLS / SRTP encrypted on the wire, ionCube-encoded provisioning modules, real-time billing via webhooks. Production-ready in a week.
Encoded provisioning modules. Encrypted SIP + media on the wire.
Every PHP module ships ionCube-encoded — proprietary IP, no readable source. Voice paths use TLS for SIP signalling and SRTP for media as standard. OAuth2 scoped tokens for the API.
Built for resellers, not retro-fitted from retail.
Same VoiceCloud platform our retail business runs on, but the reseller surface is a top-level concern, not a tacked-on tenant model. Architecture built for multi-tenant, audited from the schema up.
Built for sustained throughput
Geo-redundant SBCs across UK PoPs handle reseller-scale call concurrency without back-pressure. The same platform fronts our retail VoiceCloud — battle-tested at production load.
Multi-tenant by design
Every reseller account is a top-level tenant — your own customers, your own number ranges, your own routing rules. Cross-tenant access is impossible by architecture, not just policy.
Encrypted by default
TLS for SIP signalling, SRTP for media, OAuth2 scoped tokens for the API. Call recordings + CDR encrypted at rest. Provisioning modules ship ionCube-encoded so your reseller credentials never end up in browseable PHP.
Real-time billing API
Per-call CDR pushed to your webhook within seconds of cleardown. Margin calculated on ingest using your published rate-deck. Reconciles to the penny against monthly invoices.
Everything you'd expect, plus webhooks for everything.
The voice platform exposed via a JSON-first API + signed webhook event stream. No screen-scraper, no nightly CSV import, no Excel-via-email reconciliation. Lights-out ops by default.
SIP trunking
Reseller-tier SIP trunks with elastic concurrency. UK + international termination via tier-1 carriers. STIR/SHAKEN attestation passed through end-to-end. Failover routing per-trunk.
Hosted seats
Per-seat hosted PBX provisioning — extension, voicemail, hunt groups, IVR, time-of-day routing, 75+ features. Provision via API; the customer's first SIP REGISTER lights it up.
DID provisioning
UK + international number allocation through one API. Local geographics (every UK area code), 0330 / 0800 non-geo, mobile (07x) for SIP-to-mobile, plus international DIDs across a wide range of countries.
Call recording + CDR
Optional encrypted call recording per-trunk or per-seat, retention windows you set per-tenant. CDR streams via webhook for real-time billing or batch CSV export for accounting.
White-label mobile app
VoiceCloud iOS + Android app re-skinned with your branding — your logo, your colour scheme, your app-store listing. End-users see you, not Giant. Bundled at the seat tier.
Live rate-deck
Per-destination wholesale rates updated weekly, exportable as CSV / JSON / PDF. Build your retail markup on top, push back to your billing system via the API. No surprises at month-end.
Webhook-first ops
Provisioning, port-completion, fault-raised, CDR ingest, fraud-flag — all push as signed webhooks to your endpoints. Resellers run lights-out ops without polling.
Geo-redundant SBCs
Active-active SBCs across UK PoPs, with media anchored close to the call leg for low latency. Fast failover on PoP outage.
Three tiers. Move up as you grow.
Tiers gate concurrency + features + support cadence — not capability. Every reseller starts on the same platform; your tier just unlocks more of it. No re-platforming when you outgrow the entry tier.

Specific concurrency caps + per-minute rates per tier are published to active reseller partners. Tier upgrades are a config change — never a re-platform.
Sandbox to first production tenant trunk.
Sandbox keys within 24h of approval. Test calls into sandbox the day after. Production OAuth2 + first tenant typically inside 7 working days from signed reseller agreement.
Pairs natively with the rest of the wholesale stack.
Wholesale Voice isn't a standalone product — it's the voice layer on the same platform that delivers wholesale broadband, mobile, and numbers. Provision via the same API, bill via the same WHMCS module, support via the same reseller portal.
Real questions, honest answers.
