Platform

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, Yealink, Poly 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.

Developer-first

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.

Questions

Everything you wanted to ask.

How long does it take to launch?+

Minutes. The moment you finish signup your branded portal is live, your subdomain is provisioned, and you can buy a DID and route your first call. No waiting on carrier paperwork, no engineer required. Phones provision themselves on first boot — Grandstream and Yealink ship cold and come up configured.

Do I need to bring my own carrier?+

No. SimuWave includes carrier connectivity for North American numbers and toll-free out of the box. Bring-your-own-carrier (SIP trunking) is supported on Business and Enterprise tiers.

Is the platform truly white-label?+

Yes. Each partner gets a branded subdomain (you.simuwave.com or your own custom domain), branded email templates, and a tenant portal with your logo and color palette. Your customers never see the SimuWave brand.

How does billing to my customers work?+

You set the markup. Each tenant can be billed flat-rate (monthly fee with included extensions/DIDs/minutes) or pay-as-you-go. SimuWave bills you wholesale; you keep 100% of the margin.

What about E911?+

E911 address registration is required per DID before outbound calls (including 911) are allowed. The platform syncs to the carrier automatically and blocks outbound at the dialplan level until an address is on file. PSAP-compliant by default.

Can I migrate from another platform?+

Yes. Number porting is supported via standard LOA forms, and we will work with your existing provider to coordinate cutover. Configuration import tooling for FreePBX, 3CX, and Asterisk is available on request.

Is there a public API?+

Yes — every feature is exposed through a versioned REST API with an OpenAPI 3.0 spec. Provision tenants, extensions, DIDs, call flows, queues, and ring groups programmatically; subscribe to webhooks for call events, voicemails, and faxes. Per-partner API keys with scoped permissions. See /api-docs for the full reference.
