The business case

Why providers build their multi-tenant business on HoduPBX

HoduPBX runs every tenant, reseller, phone, carrier, and billing rule from one administration portal. That is why ITSPs, MSPs, and telecom operators use it to add customers without adding systems.

  • HoduPBX auto provisioning. Yealink, Grandstream, Fanvil, Snom phones, and many such brands pull each tenant’s settings through auto provisioning.
  • Billing built into HoduPBX. Prepaid and postpaid billing and least cost routing per tenant, with no separate billing system.
  • The HoduPBX Reseller Module. Resellers run their own sub-tenants on your platform, under their own brand.
  • Tenant admin portals. Each customer manages its own users and IVR; your team keeps platform-wide oversight.
  • BYOP (Bring Your Own Provider). Connect your own SIP trunks to HoduPBX and assign them per tenant.

Platform capability

A multi-tenant IP PBX system built for large extension counts

Whether you host a few enterprise groups or a long tail of small businesses, the platform grows by configuration. Add tenants, extensions, and sites without re-architecting the deployment.

Strict tenant isolation

Extensions, numbers, recordings, and call records stay inside the tenant that owns them.

Per-tenant resource limits

Cap channels, extensions, and concurrent calls per tenant so one busy customer never crowds out the rest.

Three-level hierarchy

Platform, reseller, and tenant levels, each with its own administrators and access rights.

Auto provisioning at scale

Supported IP phones configure themselves from per-tenant templates, so large rollouts need no desk-by-desk setup.

APIs for your OSS/BSS

Automate tenant creation, number assignment, and usage export from the systems you already run.

Provider branding for tenants

MSPs, ISPs, and ITSPs add their logo and brand assets to the portal their tenants sign in to.

How it works

One instance, as many independent phone systems as you need

HoduPBX runs as a single software instance divided into tenants. Each tenant behaves like its own phone system, with dedicated extensions, users, IVR, and reports, while the core underneath is shared, patched, and monitored in one place.

Isolated
  • Dedicated configuration per tenantEach tenant keeps its own dial plan, IVR, business hours, music on hold, and voicemail rules.
  • Separate users and credentialsTenant users sign in to their own portal and never see another customer’s users, numbers, or data.
  • Numbers that belong to the tenantDIDs are assigned per tenant, and inbound calls follow that tenant’s routing rules alone.
  • Reports scoped to each customerCall records, recordings, and reports are filtered by tenant, with a platform-wide view for your team.
  • Shared core, single upkeepUpdates, security patches, and carrier changes are applied once at platform level for every tenant.
  • Phones provisioned per tenantAuto provisioning hands every phone its own tenant’s settings, so extensions work the moment they are plugged in.

Infrastructure

Infrastructure built to carry a whole book of customers

When many businesses share one platform, isolation, provisioning, carrier control, and deployment choice come first. HoduPBX is engineered around all four.

Isolation

Separation at every layer

Extensions, dial plans, recordings, call records, and admin rights are partitioned by tenant. A change made for one customer never reaches another.

Carriers

BYOP: Bring Your Own Provider

Connect the SIP trunks you already buy, assign carriers per tenant or share a pool, and let least cost routing choose the best route for every call.

Deployment

Cloud, on-premises, or hybrid

Host the platform in your own data center, in a cloud region, or across both, so tenants with residency requirements sit exactly where they need to.

Provisioning

Phones that configure themselves

With auto provisioning, each tenant sets up its own supported IP phones, which pull their extension and feature settings on first boot. Rolling out desk phones across many customers never queues behind your team.

Resilience

Failover inside the call path

Automatic failover across routes and network links keeps every tenant’s calls connecting when a carrier or link degrades.

Tenant administration

Four screens run every tenant on the platform

Tenant setup, routing, billing, and reporting share one administration portal. Every view rolls up across the whole platform or filters down to one tenant in a click.

Every tenant, one login

Your operations team moves between tenants without moving between tools. Tenant administrators see only their own corner of the platform.

Walk through it with us

Create a tenant, hand over the keys, keep the oversight

Set up a tenant, allocate extensions and DIDs, apply your brand assets to its portal, and appoint a tenant administrator who provisions the tenant’s own phones. Your team sees every tenant on the platform; each tenant administrator sees only their own users, numbers, and reports.

  • Provider branding — tenants see your logo and brand assets when they sign in.
  • Tenant templates — launch new customers with routing, IVR, and features preset.
  • Role-based access — administrators, tenant admins, and users see only what they should.
  • Auto provisioning — tenants provision their own phones, which pull settings on first boot.

Evaluation

Questions providers ask about multi-tenant IP PBX

Multi-tenant IP PBX software runs many independent business phone systems, called tenants, on a single software instance. Each tenant has its own extensions, numbers, IVR, users, and reports, while the service provider manages the shared platform, carriers, and billing centrally. HoduPBX is built around this model for providers and enterprise groups that host voice for many customers or entities.

HoduPBX partitions every tenant at the configuration and data level. Extensions, dial plans, DIDs, recordings, call records, and reports belong to one tenant, and role-based access means tenant users and administrators can only see their own information. Your platform team keeps a consolidated view across all tenants.

It is designed for organizations that run voice for many customers or entities at once: ITSPs and VoIP providers, managed service providers, ISPs and telecom operators, and large enterprises that give each subsidiary, brand, or region its own phone system.

Yes. Each tenant can have its own administrators who add users, manage voicemail, and change IVR menus, queues, and business hours for their organization. Those changes apply to that tenant only, and your team retains full oversight from the platform level.

Yes. Prepaid and postpaid billing can be set tenant by tenant, with your own rate plans, multi-currency invoicing, low-balance alerts, and payment gateway integration with PayPal, Stripe, and CCAvenue. Resellers can bill their sub-tenants under the same rules.

Yes. HoduPBX supports a platform, reseller, and tenant hierarchy. Resellers create and manage their own sub-tenants, set their own rates, and operate under their own brand, while you keep control of the underlying platform. Partners can start through the HoduSoft partner program.

Yes. The multi-tenant architecture lets MSPs, ISPs, ITSPs, and other service providers run hosted PBX services for many clients under their own brand from a single platform. Providers can also add their logo and brand assets to the tenant portal, so every tenant signing in sees the provider they buy from.

Yes. HoduPBX supports BYOP (Bring Your Own Provider). You can assign dedicated SIP trunks to specific tenants, share a carrier pool across the platform, or combine both, with least cost routing selecting the best route for each call.

Each tenant provisions its own phones. Supported IP phones from Yealink, Grandstream, Fanvil, Snom, and many other brands register over SIP and pull their settings through auto provisioning, using templates set per tenant. Large rollouts across many customers and sites happen tenant by tenant from their own portals rather than phone by phone.

HoduPBX is sized to your tenant mix during planning, and it grows by adding resources as tenants and extensions increase, without moving customers to a new system. Per-tenant limits on channels, extensions, and concurrent calls keep capacity predictable, so one tenant’s peak hour does not affect another’s calls.

Yes. HoduPBX runs in the cloud, in your own data center, or in a hybrid of both. Hybrid deployments let you place tenants with data residency requirements on-premises while others run in the cloud, all managed from one portal.

HoduPBX comes with PayPal, Stripe, and CCAvenue payment gateway integration ready to use. Tenants receive invoices in their portal and pay directly through the gateway, and every transaction flows into billing reports. APIs let you pass payment records to your own accounting systems.

Yes. HoduPBX supports STIR/SHAKEN call authentication to help combat caller ID spoofing, and Single Sign-On with Google and Microsoft accounts.

Run your hosted voice business on one platform

Whether you're launching hosted PBX services, consolidating customer phone systems, or giving every subsidiary its own tenant, HoduPBX gives you the isolation, control, and scale to run them all from one multi-tenant IP PBX.
