SumoFiber Hosted PBX review
A hosted PBX with unlimited extensions, mobile calling, and browser-managed routing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SumoFiber Hosted PBX is a cloud-hosted business phone system for organizations replacing on-site PBX hardware, from single-line offices to multi-location enterprises. It combines business calling with auto-attendants, queues, voicemail, conferencing, and mobile apps for iOS and Android. Teams can manage greetings, queues, and routing in a browser-based admin console, while supported endpoints include desktop, mobile, desk phones, and browsers. Its unlimited extensions and included local and long-distance calling per seat make it relevant to businesses that need room to add extensions without a stated cap.
Geographic reach and continuity are notable parts of the offer. SumoFiber supports local number presence in more than 50 countries and multi-region geographic redundancy. Mobile business calling includes Wi-Fi-to-cellular handoff, and voicemail can be delivered to email or transcribed. Call management covers do-not-disturb, hold, transfer, and call park; call logging is available, with recording as an option. Integrations include Salesforce, Microsoft Teams, HubSpot, ConnectWise, Sugar CRM, Zendesk, and Gmail. These capabilities suit distributed teams that want business calling across office and mobile endpoints, though buyers seeking a highly specialized phone-only setup should compare the integration and management needs of their own workflows.
Pricing is handled through sales rather than a published product price list, and costs vary by location and are confirmed during sign-up or a sales inquiry. There is no free plan, so teams should expect to discuss their requirements before evaluating cost. Support is available by email and phone, with 24/7 support indicated, and the listed compliance capability is SSO/SAML. Choose SumoFiber if unlimited extensions, international local-number presence, browser-based routing, and mobile calling align with the organization’s needs. It is a weaker fit for buyers who require public pricing or a free tier before engaging with a vendor.
