Unlimited calling and texting under fair use. No per-minute or per-text overage charges.

Calling and texting are unlimited under fair use of 5,000 minutes and 2,000 texts per active user per month. Billing is per workspace with free unlimited users, so fair use is measured per active user, and unusually high per-workspace usage is reviewed, not charged. Very high-volume teams (call centers, bulk or autodialer calling, 24/7 outbound) should contact us for a custom plan.

  • 30-day money-back guarantee on your first plan charge.

Questions

Business phone system questions, answered.

The short version. The full list, with porting, hardware, and fair-use details, is on the FAQ page.

What is D Line?

D Line is a cloud business phone system (VoIP) for small teams. One price per workspace covers unlimited users and extensions, a business number, unlimited US and Canada calling under fair use, voicemail, apps for the browser, desktop, and mobile, and an AI receptionist. It is available in 4 languages and made by DaVinci Tech Solutions in New York.

How much does a D Line business phone system cost?

Base is $20/month and Advanced is $35/month per workspace, or $200 and $350 per year with two months free. Extra numbers are $2/month each and business texting is $5/month per 10DLC campaign.

Does D Line charge per user?

No. Both plans are priced per workspace with unlimited users and extensions, so adding a teammate does not raise the bill. Calling and texting are unlimited under the fair-use policy, with no per-minute or per-text overage charges.

Does D Line include AI call summaries, transcription, and an AI receptionist?

Both plans include an AI agent that answers calls (the Base AI agent on Base, the Advanced AI agent on Advanced) with 2,000 AI minutes per workspace per month. Advanced adds AI call transcription and summaries for about 1,000 minutes a month, and you can ask AI questions about past calls.

Which devices does D Line work on?

The browser, Windows and macOS desktop apps, iOS and Android apps, a Chrome click-to-call extension, and supported IP desk phones. Team video calling between teammates is included on Advanced.

Can I keep my existing business number?

Yes. Porting a number in is free, and eligibility and timing are confirmed before the move. You can also try D Line first: the trial is 14 days for $3, and the first plan charge has a 30-day money-back guarantee.
