Every managed service provider, PBX operator, and carrier eventually runs into the same wall. The switch works, the trunks are provisioned, the margin is fine, and then the customer opens a calling app that carries somebody else's name across the top of the screen. That app is the only part of the service most end users ever see, which makes it the part of the service that decides whether the relationship feels like yours or like a rental. A white-label softphone is how providers take that screen back. We looked at how the current crop of vendors actually behave once you get past the marketing page: what they let you rebrand, what they publish about price, what they run on, and where each one stops being a good idea.

What a White Label Softphone Actually Is

A white label softphone is a VoIP calling application that one company builds and another company rebrands and resells as its own product. The reseller supplies the logo, the colour scheme, the app store listing and, in most cases, the support relationship. The vendor supplies the client software, the push notification infrastructure and the ongoing platform work. The end user downloads an app with the reseller's name on it and never learns who wrote the code.

Underneath the branding, almost every product in this category rests on one of two call technologies, and often on both at once.

SIP, the Session Initiation Protocol, is the signalling standard that sets up, changes and tears down a call between endpoints. It is documented by the IETF, and if you want the exact behaviour rather than a vendor summary, the specification that defines it describes SIP as an application-layer control protocol for creating, modifying and terminating sessions with one or more participants. Anything that registers against your existing PBX is almost certainly speaking SIP.

WebRTC is the newer of the two, and it is what allows a call to run inside a browser tab with no installed client at all. It is standardised at the W3C, and the browser specification behind it defines a set of ECMAScript APIs that let media and generic application data be sent to and received from another browser or device. In practice, most of the vendors below use SIP for registration against the PBX and WebRTC for the web client, video, or both.

How We Compared These Platforms

We worked from each vendor's own published material as of September 2026, plus the public review profiles on Capterra, G2, Software Advice, and SourceForge. We recorded the platforms each product ships on, how deep the rebranding goes, whether the vendor publishes a price or hides it behind a quote form, and what the review base actually says. Every entry below is a genuine white label or rebrandable offer sold to resellers, not a retail app we padded the list with. Ratings are quoted as published and are not linked, because a rating is a data point rather than a recommendation. Where a vendor publishes no price, we say so rather than leaving the column blank.

White Label Softphone Providers at a Glance

The 8 Best White Label Softphone Providers

1. iotum

Best for: PBX providers, VoIP resellers and MSPs who want a branded end-user app without touching the switch underneath it.

iotum Communicator sits in front of the phone system rather than replacing it, and that distinction is essentially the whole pitch. The product page describes it as one hundred percent white-label and SIP-compatible with any PBX or carrier, which means the reseller keeps the infrastructure it already paid for and replaces only the part the customer looks at. Video conferencing is bundled into the same app rather than sold as a separate line item, which is unusual in this category and matters if you are trying to hold a customer who is being courted by Teams. The vendor sells to the channel rather than to end users, so the commercial model assumes you are reselling, not deploying internally.

What you get:

• Full-featured SIP softphone for iOS, Android, Windows, Mac and web
• Inbound and outbound calling, call routing, transfers, hold and resume, voicemail and call recording
• Enterprise-grade video meetings included in the app rather than added on
• Your logo, colours and brand styling, deployed on your own white-label domain

Rating: 5.0 out of 5 from 19 reviews on Capterra, on the vendor-level listing rather than a softphone-specific one.

Pricing: No public price list. Partner terms are quoted, and the model is per-user wholesale with the reseller setting its own retail price.

Not a fit if: you want to embed calling inside your own application rather than resell a finished app, or you need a published rate card before you will take a sales call. The public review base also reflects the wider vendor rather than this specific softphone, so there is less independent evidence about the app itself than there is for the older names on this list.

2. Ringotel

Best for: small and mid-sized providers who need to know the wholesale number today.

Price transparency is rare enough in this category that it deserves to be rewarded. Ringotel publishes per-user rates on its own site, which means a small provider can model margin on a spreadsheet before it ever speaks to a salesperson. The platform is built to sit on top of standard SIP systems including FreePBX, FusionPBX and 3CX, and branded apps are offered specifically to resellers and VoIP providers.

What you get:

• Branded mobile and desktop apps for resellers and VoIP providers
• Advanced call handling, SMS through SIP SIMPLE or API, push notifications, and cloud call recording
• Centralised provisioning through a portal or API, with onboarding emails and QR codes
• CRM integrations and single sign-on on the higher tier

Rating: 5.0 out of 5 from 14 reviews on Capterra.

Pricing: Essentials at EUR 2.49 per user per month for three devices, Pro at EUR 4.98 per user per month for six devices. No minimum commitment, with volume discounts for providers.

Not a fit if: you need a heavily bespoke interface. The customisation here is branding and feature toggles rather than a redesign, and the review base is still small enough that a single unhappy customer would move the average noticeably.

3. Acrobits Cloud Softphone

Best for: carriers and larger service providers who want to control fine detail across a big deployment.

Acrobits is the name that shows up on almost every roundup in this category, and the reason is depth rather than novelty. The company states that its platform powers more than 140 million endpoints and exposes more than 300 customisation options, which is the largest published customisation catalogue of anything we looked at. Features are modular, so a carrier that needs 911 location reporting and multi-party messaging can buy those specifically instead of taking a bundle.

What you get:

• Native iOS, Android, Windows and macOS applications
• More than 300 documented customisation options for branding and behaviour
• Modular features including push notifications, video, unified login, external provisioning, contact hub and 911 location reporting
• A separate Softphone SDK for teams embedding voice and video into their own product

Rating: 4.7 out of 5 from 10 reviews on Capterra.

Pricing: Usage-based, billed on active users rather than registered accounts. Third-party listings put the generic full-feature app at USD 69 per feature per month and the white label application at USD 549 per feature per month, so the branded tier is a significant step up.

Not a fit if: you are a small reseller. The per-feature model rewards scale, and the price gap between the generic bundle and the branded application is wide enough that a provider with a few hundred seats may struggle to make the branded tier pay.

4. Tragofone

Best for: resellers in price-sensitive markets who need volume economics more than they need bespoke design.

Tragofone competes on cost, and it does so openly. The published tiers put the entry plan under one US dollar per user per month and the middle plan under two, which is the lowest published pricing of anything in this comparison. White label branding does not appear on the entry plan, so a reseller who actually wants its own logo starts on the Standard tier.

What you get:

• Android, iOS, Windows, macOS and Linux support across the range
• WebRTC with a SIP gateway, auto provisioning and push notifications
• White-label branding, calling, video, SMS and one-to-one chat from the Standard tier
• Group chat, conferencing, CRM integrations and custom infrastructure on Premium

Rating: 5.0 out of 5 from 6 reviews on Software Advice.

Pricing: Basic under USD 1 per user per month, Standard under USD 2 per user per month, Premium quoted.

Not a fit if: you need the branding on your cheapest tier. Buying the entry plan and discovering that rebranding sits one level up is an avoidable surprise, and the review base of six is thin enough that the perfect score should be read as encouraging rather than conclusive.

5. Fonimo

Best for: providers who want to own the deployment outright and stop paying per seat.

Fonimo sells a different commercial shape from everyone else here. Instead of a per-user subscription, it offers a one-time ownership licence that covers server deployment, full rebranding, feature customisation, resell rights and unlimited users, with source code available as a separate add-on. For a provider that expects to run the same app for five years, the arithmetic on that can look very different from a monthly seat charge.

What you get:

• Android, iOS and a progressive web app
• Full white label rebranding with feature customisation
• Deployment on on-premises servers or cloud platforms
• Resell rights and unlimited users under the licence, with optional source code access

Rating: 4.8 out of 5 from 5 reviews on SourceForge.

Pricing: A one-time ownership licence with no recurring fees, quoted per project. The vendor states that deployment runs three to seven business days depending on customisation scope.

Not a fit if: you want the vendor to carry the operational burden. Owning the deployment means owning the upgrades, the app store submissions and the incident response, and the public technical documentation is vague about which protocols sit underneath, which is worth resolving before you sign anything.

6. Bria by CounterPath

Best for: buyers who value a long track record and broad desktop coverage over novelty.

Bria has been in enterprise deployments for years and has the review volume to prove it, which is the main argument for choosing it. CounterPath runs a branding portal that lets a partner change the product name, logos, colours, call control functions, codecs, available features, provisioning settings, languages and defaults, with a support team attached to the process. The client itself runs on more platforms than most, including Linux and rugged devices.

What you get:

• Mac, Windows, Linux, iOS, Android, tablets and rugged devices
• A branding portal covering name, logo, colour, codecs, features, provisioning, languages and defaults
• Optional messaging, screen sharing and video conferencing modules
• A separate desktop API for automation work

Rating: 4.4 out of 5 from 69 reviews on G2, the largest review base in this comparison.

Pricing: The retail plans are published at USD 2.95 per user per month for Bria Solo and USD 4.95 for Bria Teams on annual terms. White label deployments are quoted separately by the sales team.

Not a fit if: you need the branded tier priced without a conversation. The retail numbers are public and the white label numbers are not, which makes early margin modelling harder than it needs to be. This is also the name that appears on nearly every competing roundup, so being on it will not differentiate your service from the reseller down the road.

7. Zoiper

Best for: OEM projects with a defined user base and an internal development team.

Zoiper's white label work is genuinely OEM in character. The company offers branding as an outsourced service or SDK access for teams that would rather build the interface in house, and the enquiry form asks for a projected user count in bands running from under a thousand to over a hundred thousand, which tells you plainly that pricing scales with volume. Customisation covers logo, corporate colours, custom fonts, icons and per-group feature provisioning, and the client is IMS, RCS and VoLTE ready.

What you get:

• Windows, Mac, Linux, Android and iOS clients
• Logo, colour, font and icon customisation plus custom interface development
• Smart provisioning that assigns different features and licences to different user groups
• IMS, RCS and VoLTE readiness for carrier-grade deployments

Rating: 4.4 out of 5 from 53 reviews on G2.

Pricing: The retail client is free for non-commercial use, with premium licences at EUR 11.11 for desktop, EUR 7.99 for Android and USD 4.99 for iOS. Branded OEM versions are priced on demand against your projected user band.

Not a fit if: you are small. A vendor whose smallest published band starts at zero to one thousand users and runs to over a hundred thousand is optimised for the top end of that range, and the free tier being non-commercial means it gives you nothing to test a reseller model with.

8. Linphone

Best for: organisations with in-house developers, an auditing requirement, or both.

Linphone is the open source option, and the trade it offers is control in exchange for time. The core software is open source and free to build against, which means a team with the right skills can put a branded client into the field without paying a licence at all. The commercial white label programme sits on top of that: logo, app name, colour scheme, custom login flows including QR code and SSO, selective feature enablement and help with Apple and Google store submissions.

What you get:

• iOS, Android, macOS, Windows and Linux support
• HD voice and video, video conferencing for up to 50 participants, messaging with file sharing
• End-to-end encryption and an auditable open-source codebase
• Logo, name, colour and login customisation, with app store submission assistance

Rating: 4.0 out of 5 from 15 reviews on Capterra, the lowest average here.

Pricing: The core software is open source and free. The white label programme is quoted per project, with an annual maintenance contract for ongoing support. The vendor puts first delivery of a branded version at roughly eight weeks.

Not a fit if: you need something in the field this quarter. Eight weeks to a first build is before your own testing and store review; reviewers repeatedly describe the interface as dated, and support responsiveness is the most common complaint in the public reviews. Open source is only cheap if your team's time is free, which it is not.

Pricing Models for White Label VoIP Phone Solutions

There are four commercial shapes in this market and they are not interchangeable.

The per-user subscription is the most common. Ringotel and Tragofone both publish theirs, at EUR 2.49 and under USD 1 respectively at entry level. It is the easiest model to resell, because your cost scales with your revenue and you can price retail at a fixed multiple of wholesale.

The per-feature or usage model is what Acrobits uses, billing on active users rather than registered accounts. It suits providers with a large but partly dormant base, and it punishes providers who want every feature switched on for a small deployment.

The one-time ownership licence is Fonimo's approach. You pay once, you deploy it yourself, and you stop paying. The catch is that you also inherit the operational work, so the real cost is the licence plus whatever your engineers spend keeping it alive.

The quote-only model covers iotum Communicator, the branded tiers at CounterPath, Zoiper's OEM work and Linphone's commercial programme. There are defensible reasons for it. Branded deployments vary enormously in scope, and a published number would be wrong for most buyers. It is still worth naming the cost to you, which is that you cannot model margin until you are already several conversations deep with a vendor.

One thing to watch across all four: the reseller sets the retail price, so the wholesale rate is only half of the calculation. A vendor charging EUR 2.49 that you resell at EUR 9 is a better business than a vendor charging EUR 1 that your market will only bear EUR 3 for.

How to White Label a Softphone With Branding Guidelines

Rebranding a softphone turns out to be more of a compliance exercise than a design one, and the order in which you do the work matters quite a lot.

Start with the brand assets themselves. Every vendor here wants a logo in several resolutions, a primary and secondary colour, and an app icon. The icon is the constraint people underestimate: Apple and Google both reject icons that are too close to an existing listing, and a generic blue handset on a white circle has been submitted several thousand times already. Give the designer the store guidelines before the brief, not after.

Then decide who owns the developer accounts. Some vendors publish under their own account and hand you a listing you do not control. Others ask you to hold your own Apple Developer and Google Play accounts and publish on your behalf, which costs a little more administratively and leaves the listing, the reviews and the update schedule in your name. The second arrangement is almost always worth the extra paperwork, because an app store listing you do not own is a customer relationship you do not fully own either.

Next, work through the feature set you are exposing. Most platforms let you hide functions as well as rename them, and resisting the temptation to enable everything is usually correct. Every feature you turn on is a feature your support desk has to explain.

Finally, deal with the regulatory layer before launch rather than after. In the United States, providers of interconnected VoIP carry emergency calling obligations, and the FCC states that they must obtain a customer's physical location before service activation and provide easy ways to update it, and must transmit all 911 calls along with a callback number and the caller's registered physical location to the appropriate emergency call centre. Read the rules covering registered caller location properly, because your branded app is the interface where that location gets captured and where a regulator will look first. Ask any prospective vendor how their client handles registered location and whether it supports 911 location reporting natively, then get the answer in writing.

Comparative Features of Top White Label Softphones for SMBs

Most resellers in this market are not carriers. They are managed service providers and PBX operators selling to businesses with somewhere between five and two hundred seats, and that changes which features actually matter.

For an SMB-focused reseller, published per-user pricing is worth more than customisation depth, because margin has to be provable on a small deployment. Ringotel and Tragofone are the two that let you do that arithmetic before a sales call. Bundled video is the second differentiator, because SMB customers compare your service against Teams and Zoom whether or not that comparison is fair, and a calling app with no video attached loses that comparison instantly. iotum Communicator and Linphone both include video in the base product rather than selling it separately.

Desktop coverage matters more than most vendors admit. An SMB with a mixed fleet of Windows and Mac machines will have somebody on Linux, and Bria and Zoiper are the two here that cover all three. Provisioning is the last one. Onboarding a twenty-seat customer by hand is tolerable once and intolerable at the tenth account, so QR code or API provisioning is a real operational saving rather than a spec sheet item.

Where SMB resellers usually overbuy is customisation. Acrobits offers more than 300 options, which is a genuine advantage at carrier scale and a distraction at forty seats.

The Bottom Line

The market has settled into two camps. One group sells deep customisation to carriers and prices it accordingly. The other sells a fast, cheap branded app to resellers and keeps the configuration surface small. What has been missing from most roundups is the middle case, which is the provider that already owns a working phone system and wants a better app on  top of it without a migration project attached.

If that is your situation, and the search that brought you here was best white label softphone solution rather than a shopping trip for a new switch, iotum Communicator was designed for exactly that buyer: a white label softphone with bundled video for PBX providers, VoIP resellers and MSPs, sitting on the infrastructure you already run. If your priority is a published per- seat number you can model this afternoon, start with Ringotel. If you are operating at carrier scale, Acrobits remains the benchmark for a reason.

Whichever way you go, ask two questions before you sign. Does the vendor register against my existing system, or does this become a migration? And whose name is on the app store listing when we are finished?
