Questions to ask any provider
Is recording included?
Some plans add call recording only on higher tiers or as an add-on.
What about AI?
Check which tier includes transcription, summaries, or an AI receptionist, and whether AI is billed per minute or per conversation.
How is texting billed?
Look for per-user text caps, pooled allowances, and registration fees.
Is there a term?
Annual prices often need a 12-month commitment. D Line is month to month or annual, your choice.
Does porting cost anything?
D Line does not charge to port your number in. Ask your current provider about port-out fees.
Who answers support?
D Line has 24/7 live human support on every plan.
Questions
Frequently asked questions
How much does a business phone system cost per user?
Published small-business plans we checked in Oct 2026 range from about $10 to $75 per user per month, depending on the provider, the tier, and whether you pay monthly or annually. D Line is $20 or $35 per workspace, not per user.
When is a per-user plan cheaper than D Line?
Usually for one or two people on an entry plan. For example, one user on a $10/user plan costs less than D Line Base. The calculator shows the break-even point for your team size.
Does the calculator include taxes and fees?
No. It compares list prices only. Taxes, regulatory fees, add-ons, and hardware vary by provider and location.
What does D Line include for the workspace price?
Unlimited users and extensions, one US number, unlimited US and Canada calling under fair use, call recording, voicemail with transcription, call menus and ring groups, and an AI agent with 2,000 AI minutes a month. Advanced adds AI transcription and summaries, auto recording, call queues, and team video calling.
