Ooma

Ooma Office is purpose built for the smallest end of the business phone market: offices from one phone to a few dozen that want a professional system, auto attendant, extensions, mobile app, voicemail to email, without involving IT, because there is no IT. Setup is genuinely self install, hardware options include preconfigured desk phones, and administration stays simple enough for whoever happens to run the office. The pricing model is its quietest differentiator: flat published tiers from roughly twenty to thirty dollars per user per month, month to month, with no annual contract required, which is increasingly rare in this category and exactly right for a small business that does not want to model multi year scenarios. The company is a stable, publicly traded specialist in exactly this market and has been expanding it through acquisitions of other small business phone providers. The honest limits are the flip side of the simplicity: complex routing, deep integrations, and larger multi site deployments are not what it is for, and growing companies eventually graduate to the platform vendors. For the small office that wants the phones handled without a project, a consultant, or a contract, Ooma is the shortest path.
