OnSIP is a hosted business phone service with phones included in a $18.95 per-user plan, sold month to month. But the plan needs 5 users, call recording and enhanced queues are paid add-ons, and the sign-up page says it does not serve anywhere outside the U.S. and Canada. - **Value for money: C.** $18.95 per user a month with a 5-user minimum, against a category middle of $19. The $49.95 pay-as-you-go account bills calls at 3.2 cents a minute on top. - **Free plan and trial: F.** No free plan and no trial on record. The listing shows only the paid Unlimited and Pay-as-you-go accounts. - **Features: C.** Auto attendants, ring groups, ACD queues, SMS and MMS are all listed. But recording is $4.95 per user a month, enhanced queues $14.95 and E911 $1.80, so the basics come with a meter. - **Ease of use: C.** No store rating on record. It needs phones or apps set up, auto attendants and rules built, and each feature switched on and priced. - **Platforms and integrations: A.** Softphone apps for Mac, Windows, Linux, iOS and Android, a browser app and any SIP device, plus HubSpot, Zendesk and Odoo and an open API.

That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 25 of the 44 other business phone systems grade higher. It costs $227.40 a year. - You could not: Phone numbers and calls carried over the phone network. - You could not: Texts from a business number, registered with the carriers. - You could not: Apps for macOS, Windows, Linux, iOS and Android that stay in step with each other. - You could not: It is priced for each person, which means accounts and billing for a team. - You could not: It plugs into other products, HubSpot, Zendesk and Odoo among them, and has an API.
