FAQ:

What use cases does the platform support (calls, messaging, contact center)?

iotum’s white-label softphone platform is designed to power a wide range of branded, real-time voice workflows under your name. Teams use it to deliver a modern white-label VoIP softphone experience for 1:1 calls, team calling, and customer support, directly inside their own product or service, without pushing users to a third-party dialer.

It supports everyday business calling and advanced voice scenarios like inbound/outbound calling, call routing, call transfers, hold/resume, voicemail, call recording (where enabled), and multi-device access, useful for sales teams, customer success, field service, and distributed operations. For service providers and platforms building communications into their stack, iotum enables embedded calling experiences that fit self-serve user journeys as well as operator-managed or admin-controlled environments.

Overall, iotum helps you launch a flexible white-label VoIP softphone solution for business calling, support, and voice-enabled collaboration, fully branded and product-ready.

Can we use our own logo, colors, and domain?

Yes. iotum’s white-label softphone platform is built so the calling experience looks and feels like your product, not iotum’s. You can apply your own logo, colors, and brand styling across the softphone UI so users experience a consistent identity from login to dial pad to call controls.

For deeper brand control, iotum can support deployments using your own white-label domain, so users access the white-label VoIP softphone through a URL aligned with your product or service. And if you’re embedding voice into an existing app, iotum’s API/SDK approach is designed to help you deliver a fully integrated white-label VoIP softphone solution with UI and workflows that match your product design.

Does it support HD voice quality?

Yes. iotum’s white-label softphone capabilities are built to deliver high-definition VoIP audio so you can offer a premium calling experience under your own brand. With a white-label VoIP softphone, call clarity and consistency are core expectations, so the platform is designed for modern, reliable voice performance that fits business calling, customer support, and everyday team communication.

This makes iotum a strong option when you want a white-label softphone solution that feels professional and polished, without forcing users to download or switch to a third-party calling app.

What are the user, agent, and concurrent call limits?

A white-label VoIP softphone platform is typically structured around provisioning, meaning limits depend on how many users/agents you enable and what concurrency you need. With iotum, capacity is commonly aligned to your deployment and plan configuration, so you can scale from a small internal team to a larger customer-facing voice operation.

In practical terms:

  • User/agent capacity is based on the number of accounts or seats you provision.
  • Concurrent calling capacity is based on how many simultaneous calls your environment is configured to handle.
  • Admin/manager roles can be set up across your organization depending on how you structure teams and customers.

Because iotum supports white-label softphone deployments, these limits can be mapped to your packaging, so you can offer different call capacity tiers across customers and plans.

How stable is the platform at scale with many active users and calls?

iotum’s white-label softphone platform is designed for stability across different usage levels, from low-volume internal calling to high-volume customer interactions. The underlying voice architecture is built to support consistent performance as your user base grows, helping maintain call quality and continuity even as you add more agents, endpoints, and simultaneous conversations.

For providers offering a white-label VoIP softphone solution, this matters because scale isn’t just “more users”, it’s more concurrent sessions, more routing scenarios, and more real-world network conditions. iotum’s approach is positioned to keep voice quality dependable across geographies and usage spikes, so your customers get a solid calling experience that still looks and feels like your brand.

What browsers and devices are supported? Any limitations on mobile?

iotum’s white-label softphone platform is built to meet users where they work, on desktop and on mobile, so you can deliver a consistent white-label VoIP softphone experience across common devices.

  • Desktop/Laptop: Users can typically access calling through modern web and desktop environments, making it easy to deploy a branded softphone without requiring specialized hardware.
  • Mobile (iOS/Android): Native mobile app support enables on-the-go calling with a more consistent feature set and performance than mobile browsers in many real-world conditions.

Mobile limitations: as with most VoIP and real-time communications experiences, results can vary on mobile browsers depending on the device, OS version, and browser behavior. For the most reliable call quality, notifications, and background calling behavior, iotum’s white-label VoIP softphone deployments generally favor native mobile apps for smartphones and tablets.

Do you support call features like transfer, recording, chat, and call controls?

Yes. A modern white-label softphone solution needs more than “dial and talk,” and iotum supports the core calling and collaboration capabilities businesses expect under your brand.

Common softphone features include:

  • Call transfer (warm/blind, depending on configuration)
  • Hold / resume / mute
  • Voicemail and call history
  • Call recording (optional, deployment-dependent)
  • In-app messaging / chat for quick coordination during customer calls and internal collaboration
  • Admin controls for managing users, numbers, and calling policies (based on your setup)

These features help you package a full white-label VoIP softphone offering for sales teams, support desks, and distributed organizations, without sending users to an external calling app.

Can we control user permissions and roles?

Yes. iotum’s white-label softphone platform supports role-based control so you can manage who can place certain types of calls, access recordings, use advanced call handling features, or administer teams and accounts.

Typical controls include:

  • Admin vs. user/agent roles
  • Permissions for recording, call routing actions, and feature access
  • Team-level provisioning so different departments or customer accounts can have different rules

Because it’s a white-label VoIP softphone solution, you can align these roles and permissions with your own product tiers and governance requirements, so the experience scales cleanly across multiple customers, teams, or tenants.

Can we embed a white-label softphone directly inside our product?

Yes. iotum’s white-label softphone approach is built so you can deliver in-app calling inside your own web or mobile experience, without redirecting users to a separate dialer or third-party VoIP app. Using iotum’s integration tooling (API/SDK options depending on deployment), you can bring white-label VoIP softphone functionality into the exact places users already work: account portals, customer dashboards, agent consoles, mobile apps, and embedded support flows.

That means your customers can place and receive calls, manage call controls, and handle voice interactions while staying fully inside your branded product environment.

Can we build custom workflows on top of the platform?

Yes. iotum’s white-label VoIP softphone platform is designed to support customization so you can shape calling around your business logic, not the other way around. With API-driven provisioning and integration hooks (such as REST-style endpoints and event/webhook patterns, depending on your setup), you can create voice workflows that match your product experience, including:

  • In-app click-to-call from CRM records, tickets, or user profiles
  • Onboarding and activation flows that provision users, numbers, or calling permissions automatically
  • Support escalations that move from chat to voice with context preserved
  • Scheduling-to-call journeys (e.g., reminders → tap-to-call → post-call notes)
  • Routing and queue logic aligned to your teams, customers, or account tiers

This makes it practical to package a branded white-label softphone solution with unique workflows, role controls, and automation that differentiates your offering.

What security and compliance standards do you meet?

iotum positions its white-label softphone capabilities for organizations that require enterprise-grade privacy, security, and compliance, especially in regulated industries where voice data and user identity must be handled carefully.

Commonly emphasized areas include:

  • GDPR alignment for personal data handling in global deployments
  • Published privacy policies outlining how data is collected, used, and protected
  • Healthcare-ready compliance posture, including support for HIPAA-aligned workflows (deployment dependent)

If you’re launching a white-label VoIP softphone for regulated customers, the key advantage is that you can keep voice interactions inside a controlled, branded environment with governance options that match your security requirements.

What level of support do we get during onboarding and after launch?

iotum’s white-label softphone programs are typically backed by hands-on enablement during rollout and continued assistance once your white-label VoIP softphone is live under your brand.

During onboarding

You can expect a guided implementation path to help you launch a branded white-label softphone solution faster and with fewer surprises.

Onboarding support commonly includes:

  • Setup and configuration help for your white-label environment (branding, tenant structure, roles, and feature policies)
  • Developer resources for API/SDK-based embedding and provisioning (docs, quick-start guides, integration references)
  • Technical alignment on call flows, user management, and deployment requirements so your softphone experience matches your product

If your go-live involves high-visibility customer usage (like a major rollout to many agents or customers), iotum’s support structure is designed to help you plan for stability and smooth adoption.

After launch

Post-launch, iotum provides ongoing operational support to keep your white-label VoIP softphone reliable at scale. This typically includes 24/7 assistance via phone, email, and chat, helping your team troubleshoot issues, maintain service quality, and respond quickly when end users need help.

Net-net: you get structured support for both the initial launch of your white-label softphone and the long-term operation of your branded VoIP calling experience.

Does the softphone reliably ring on iOS and Android?

Yes. iotum uses VoIP push notifications so an incoming call wakes the app and rings on iOS and Android even when the app is backgrounded or the phone is in battery-saver, using the operating system's native incoming-call handling rather than a background process the phone can suspend. Reliable ringing is the number one thing to check in a softphone, so it is the first thing we demo.

Does iotum work with my existing PBX, including NetSapiens?

Yes. iotum is a SIP-based white label VoIP softphone, so it registers to the PBX and carrier you already run, and iotum is a listed integration partner of NetSapiens. You keep your switch, your numbers and your routing, and iotum becomes the branded app your customers use. There is no back-end migration and no rip and replace.

How much does a white label softphone cost, and how is it priced?

iotum is priced on a wholesale, per-seat model. You license the platform at a wholesale rate and resell it at a price you set, so the margin is yours. One rate covers softphone, video, messaging and webinars, rather than an add-on charge for every feature, with minimal startup costs. There is no fixed public price because every reseller packages differently, so your partner demo covers the numbers for your volume.

Should we build our own softphone or white-label one?

For most service providers, white-labeling is faster and cheaper than building. A softphone that rings reliably on every operating system and handles push, provisioning and app-store publishing, and keeps pace with every iOS and Android change, is a large and ongoing engineering commitment. With iotum you brand and ship an existing, maintained white label VoIP softphone in days and keep your PBX.

How is iotum different from Acrobits or Bria?

Acrobits and Bria are established softphone apps. The practical difference for a reseller is packaging and ownership: iotum bundles softphone, video, messaging and webinars under one price and one brand, runs on the PBX you already operate, and is sold through a partner model so you own the customer, not just a dialer.

How much does iotum cost?

iotum is sold to resellers on a wholesale, per-seat model. You license the white label VoIP softphone at a wholesale rate and resell it at a price you set, so the margin is yours to keep. One rate covers softphone, video, messaging and webinars, rather than an add-on charge for every feature, and startup costs are minimal. There is no rigid public price list because every reseller packages differently, so your partner demo covers the exact numbers for your volume. That single-price model is the practical difference resellers feel against Acrobits-style pricing, where video and messaging are billed on top.
