Where they actually differ
Three places, and one of them will probably decide it for you.
Texting allowance. Ooma's published plans list 250 messages a month on Pro and 1,000 a month on Pro Plus. Ours is 1,000 outbound per user per month under fair use, pooled across the account. On a three-person account that is 3,000 against 1,000, and Ooma's entry Essentials plan does not list texting at all.
Trying it. We publish a seven-day self-serve trial. Ooma's plans page publishes no trial. If you want to test a phone system with your own number and your own calls before committing, that difference is the whole conversation.
Running more than one business. Ours is built around it: a separate number, greeting, routing and voicemail for each business inside one account and one app, on every plan. Ooma is positioned around one business with users in it.

Where Ooma wins, said plainly. Their included toll-free number with 500 inbound minutes a month is a real inclusion that we charge for, and their published no-contract terms match ours. If a toll-free number is central to how you present the business, price that difference properly.
What you are actually choosing between
A tested trial against a quoted plan. Seven days with your own number tells you things no specification sheet does: whether the app rings when your phone is locked, whether the transcription is any good, whether support answers. We publish that trial; their plans page does not.
Texting at the volume a business actually sends. Appointment reminders, confirmations and follow-ups add up faster than people expect. Check the allowance against a normal week before choosing on the headline price, with either of us.
One company against several. If you run one business, this difference costs you nothing and you should decide on the rows above. If you run two or three, it is the reason this page exists.
When Ooma is the better choice
If a toll-free number with inbound minutes included matters more to you than texting volume, Ooma includes one and we do not. If you want a hardware-first setup with physical handsets as the main way people work, that is a product they have built around for a long time. And if your business is one company with a stable team rather than a founder running several things, most of our differentiator does you no good.
Choose SoundLine if you want to try it before you buy it, if you text customers at any volume, or if there is more than one business.
Questions founders ask
Does Ooma Office have a free trial?
Their plans page does not publish one. SoundLine's is seven days, self-serve, with every Growth feature switched on.
How many texts does Ooma include?
Their published plans list 250 messages a month on Pro and 1,000 on Pro Plus. SoundLine's fair-use allowance is 1,000 outbound per user per month, pooled across the account.
Is Ooma cheaper than SoundLine?
At the entry tier they are four cents apart, $19.95 against $19.99 monthly. SoundLine's annual rate of $14.99 is lower, and the comparison that matters is the texting allowance and whether you can trial it.
Does Ooma require a contract?
Their pricing page states no contract is necessary. Ours is month to month as well.
Can I run two businesses from one Ooma account?
Ooma is positioned around a single business with users. SoundLine gives each business its own number, greeting, routing and voicemail inside one account.
