Business phone systems, compared honestly

How to read this

Three things decide most of these purchases, and none of them is the headline price.

What you commit to. A twelve-month term against a seven-day trial is a bigger difference than five dollars a seat. Some of these providers will not sell you anything without a conversation and a contract.

What the headline price excludes. Toll-free numbers, unlimited minutes, analytics, call recording and meeting capacity are add-ons at several providers. Price the configuration you would actually run.

Whether you can test the thing you care about. A trial with texting disabled does not tell a small business what it needs to know.

Entry pricing and terms

Every figure from each provider's own published pricing page, 22 October 2026. Prices move; re-check before you decide.

Two entries in that table are doing something unusual. Grasshopper prices by account rather than by user, with unlimited users on a flat rate, and charges for extra numbers and extensions instead. Aircall will not sell fewer than three licenses, so its real entry cost is ninety dollars a month rather than thirty. Neither is hidden; both are easy to miss.

And one is doing something worth noticing. 8x8 publishes no prices. Its pricing page offers custom packages and a quote request. That is a normal way to sell to enterprises and an obstacle for a small business trying to compare.

Contracts

If you are not certain you will still want this in a year, the term matters more than the rate. One of these mistakes costs you a month. Another costs you eleven.

Texting

The row most small businesses get wrong, because it is rarely on the pricing page.

Aircall and Grasshopper beat us here and we are not going to pretend otherwise. If outbound texting volume is the center of your business, price those two properly before you decide.

And the row worth staring at is RingCentral's. Twenty-five outbound messages per user per month on their entry plan, roughly one a day. Their Business SMS Booster add-on is $25 per user per month, more than the Core plan it is fixing, and their trial terms switch SMS off, so a prospect cannot discover this while testing.

Which to choose, by situation

You are one person, or two. SoundLine, Quo or Grasshopper. Aircall will not sell you fewer than three licenses. Grasshopper is the cheapest if you want several people answering and do not need video, scheduling or desk phones.

You run more than one business. SoundLine. This is the thing the product is organized around rather than a feature bolted on, and it is the reason this page exists on our site rather than someone else's.

You are running a contact center or a sales floor. Dialpad or Aircall, or 8x8 at larger scale. Skills-based routing, queue priority, callback requests and power dialing are real products and we do not have them.

You want deep CRM workflows wired into the dialer. Aircall's integration catalog is larger than ours.

You want live AI transcription above all else. Dialpad, where it is mature and included on the entry plan.

You have a procurement process and an account team. Nextiva, RingCentral or 8x8 are built for that way of buying. RingCentral in particular prices in bands by user count and its catalog runs to contact center, webinars, events and rooms.

You want a clean second line for a small team. Quo. It does that well and you will not be unhappy.

You want desk phones, routing and someone to call, without an annual contract. SoundLine or Ooma.

Where SoundLine loses

Stated plainly, because a comparison page that never concedes anything is an advertisement.

• Aircall includes four times our outbound texting per user, and Grasshopper publishes unlimited texts.
• Dialpad and RingCentral give twice the trial length, fourteen days against our seven.
• Grasshopper is cheaper for several people if you want unlimited users on a flat rate.
• We have no free tier, and several competitors have one or something close to it.
• We are smaller than RingCentral, Dialpad, Vonage and 8x8. For some buyers the bigger company is the right answer, and we would rather say so than argue otherwise.
• No contact center product. If you need one, we are not the answer.

Where SoundLine wins

• One seat. No minimum, no annual commitment required to get the published rate.
• Several businesses, each its own account, with its own number, greeting, routing and voicemail, and one login that reaches all of them, on every plan including the entry tier.
• Under five minutes to a working number, measured on video rather than estimated.
• Our own network since 2008, so a call delivery fault is investigated by the company you pay.
• Texting registered with the carriers for you, rather than handed to you as a form.

Comparing two of these in particular

If you have narrowed it to a specific pair, each of these goes deeper than the table above, with the same rule: SoundLine is not one of the two names and appears once, near the end, as a third row rather than a conclusion.

• RingCentral vs Dialpad — the largest pair, decided mostly on texting shape and whether automatic recording matters
• RingCentral vs 8x8 — one publishes prices and one does not, which is most of the comparison
• RingCentral vs Nextiva — five dollars a seat against a twelve-month term
• RingCentral vs Grasshopper — per user against flat rate, which is arithmetic rather than opinion
