Start a VoIP company this weekend.
We're the rest of the stack. Carrier-grade SIP, multi-carrier DID inventory, visual call flows, zero-touch provisioning, white-label billing, mobile apps, STIR/SHAKEN, E911 — all under one platform. Sign up, claim your subdomain, and start billing customers the same afternoon.

The whole stack, already wired up.
SimuWave isn't a phone system. It's a phone company in a box. Every line below is something you'd otherwise build, integrate, and maintain yourself before you could sign your first reseller customer.
Building this stack yourself: ~$300k in engineering, 12–18 months to a working v1, plus ongoing maintenance, carrier contracts, and compliance overhead. Tomorrow vs. eighteen months from now.
Everything you need to run a VoIP business.
Not a thin shell over an open-source PBX. A full reseller platform with tenant isolation, billing, provisioning, and compliance baked in from day one.
Visual call flow designer
Drag-and-drop IVRs, time conditions, ring groups, and voicemail. Ship complex call routing without writing dialplan.
Instant DIDs & toll-free
Search by area code or rate center. One-click purchase, automatic dialplan provisioning, and E911 registration baked in.
Zero-touch phone provisioning
Ship phones cold. Grandstream and Yealink auto-configure on plug-in with button layouts and expansion modules pre-baked.
True multi-tenant white-label
Custom subdomains, branded portals, isolated billing per tenant. Your customers never see SimuWave — only your brand.
Find Me / Follow Me
Per-extension FMFM with simultaneous or sequential ring strategies. Mobile failover, custom no-answer actions, voicemail fallback.
Recording, transcripts & CDRs
Per-tenant call recording with searchable transcripts. Real-time CDRs, usage reports, and per-extension billing breakdowns.
Fax over IP
T.38 fax with email-to-fax, fax-to-email, contact lists, and cover sheet templates. Per-tenant fax users with role-based access.
Built-in fraud protection
Per-DID E911 enforcement, automatic IP banning, fail2ban integration, suspension cascades, and partner-level firewall rules.
Automated billing
Stripe-backed subscriptions with prorated upgrades, flat-rate or pay-as-you-go tenant plans, and 14-day grace periods.
Every feature, fully scriptable.
A complete REST API with an OpenAPI spec covers every surface of the platform — tenants, extensions, phone numbers, call flows, queues, ring groups, voicemail, fax, invoices, webhooks, and call records. Build internal tooling, automate onboarding, or wire SimuWave into your existing OSS/BSS stack.

Pick your subdomain
Sign up, claim your white-label portal at yourname.simuwave.com (or bring your own domain), and pick a plan.
Buy DIDs & spin up tenants
Search by area code, register E911 in the same flow, then create branded tenants for each customer with isolated billing and call routing.
Provision phones & go live
Add extensions, ship phones, and they auto-configure on first boot. Build call flows visually. Start billing your customers from your dashboard.
Pick the stage you're in.
Plans map to where your VoIP business is today — not arbitrary feature counts. Switch tiers anytime. No setup fees, no contracts.
All plans include white-label branding, visual call flows, phone provisioning, fax, and per-tenant billing. You set your retail markup — keep 100% of the margin.

SimuWave isn't for everyone.
If any of these are you, we'd rather send you somewhere better-suited than waste your trial.
If you only need phones for your own company — any size, individual or team — you don't need a reseller platform.
Try Harold Ragan CommunicationsIf you want to tinker with dialplan files on a Raspberry Pi for fun, you'll be happier with free open-source software than a commercial reseller platform.
Try FreePBXIf your average customer pays under ~$100/month, the per-tenant economics are tight. Either raise your price, or consider an end-user product instead.
