The best white-label VoIP and business phone reseller programs in 2026

A white-label VoIP reseller program lets you sell phone service under your own brand while the provider runs the network, the numbers and the compliance. Some programs sell a simple business line that forwards to any phone; others sell a full cloud phone system with softphones, desk phones and a contact center. Here is how the main options compare in 2026.

Quick comparison

1ResellPortal

ResellPortal sells a business phone line under your brand: a real local number in the US or Canada, or a US toll-free number, that rings any phone the client chooses. Each line includes 500 minutes a month with usage alerts, voicemail with transcripts, a phone menu with up to five options, missed-call texts, outbound calls that show the business number and a log of the last 100 calls. Wholesale is $10 a month per number, or $27 quarterly, $50 for 6 months and $90 a year, with no monthly platform fee and a $20 wallet to start (a first deposit of $20 or more gets a $10 bonus).

Clients pick their number on your store and run it from a phone dashboard in your brand, in any browser, with no hardware or app to install. When a client also owns the CRM, every caller becomes a contact automatically. Clients pay you through your own Stripe or PayPal, and the REST API and MCP server let you automate orders. The trade-off: this is a business line that forwards calls, not a full cloud phone system. Calls are not recorded, two-way texting is not available, and UK and Australia local numbers need a one-time regulatory registration first.

2SkySwitch

SkySwitch, a BCM One company, is a white-label UCaaS platform that MSPs, ISPs, VARs and office equipment providers brand as their own. It covers voice, contact center, business SMS, virtual fax, video, mobile and desktop softphones and a Microsoft Teams connector, plus brandable billing and taxation and an API. Pricing is not published; you start with a demo.

3Intermedia

Intermedia offers several partner models for its Unite phone system and contact center. In the CORE reseller model you sell under your own brand: Intermedia bills you a wholesale price, you set the customer price and it handles the telecom taxes. In the Advisor model you sell the Intermedia brand and earn a one-time spiff plus a monthly recurring commission.

4Viirtue

Viirtue is a white-label VoIP, UCaaS and AI voice platform for MSPs, ISPs and resellers, with your brand on portals, softphones and invoices. Its ViiBE engine handles quoting, billing, usage rating and telecom tax. Viirtue advertises 70 to 75% margins; platform pricing is not published.

5Telnyx

Telnyx sells phone numbers plus voice and messaging APIs directly to developers. Numbers start at $1 a month with a $0 platform fee, and local, toll-free and international numbers come from one API. It is a set of building blocks, so you build the customer-facing product and the brand around it.

63CX

3CX is phone system software that partners run on premise, in a private cloud or as 3CX Hosted, licensed by simultaneous calls with a flat annual fee rather than per user. Partners choose their own SIP trunk provider and move through five levels with revenue targets starting at 1,000 EUR, USD or GBP a year, with no long-term contract.

7Nextiva

Nextiva's partner program pays channel partners recurring commissions, lifetime margins and SPIFFs, with flat payouts for referral partners and affiliate commissions through PartnerStack. You sell the Nextiva brand with co-branded marketing rather than your own, so it fits partners who want commission income without running the service.

How to choose

• Selling to small local businesses: a number with voicemail, a phone menu and missed-call texts covers most needs. ResellPortal sells that at $10 wholesale with no platform fee.
• MSP selling full phone systems: SkySwitch, Intermedia, Viirtue or 3CX.
• Building your own phone product: Telnyx numbers and APIs.
• Commission without owning the customer: Nextiva or Intermedia's Advisor model.

Common questions

Can I resell VoIP phone numbers under my own brand?

Yes. ResellPortal sells local US and Canada numbers and US toll-free numbers on your store, with your brand on the phone dashboard and the emails. SkySwitch, Viirtue and Intermedia's CORE model also let MSPs sell a full phone system under their own brand.

How much does a white-label business phone number cost?

On ResellPortal it is $10 a month per number at wholesale, including 500 minutes, against an example retail price of $29. Telnyx numbers start at $1 a month for developers who build their own service. UCaaS platforms such as SkySwitch and Viirtue price through their sales teams.

Do my clients need a desk phone or an app?

Not on ResellPortal. Calls ring whatever phone the client chooses, and the dashboard works in any browser on a computer or a phone. UCaaS platforms such as SkySwitch include softphones, and Intermedia offers pre-configured devices for offices that want them.

Can I try a white-label phone dashboard before I sell it?

Yes. ResellPortal has a live demo of the full phone dashboard with sample calls, voicemails and settings, and nothing in it is saved.
