Abbax Business Phone System review
A feature-rich cloud phone system for mid-size teams that still need deskphone support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Abbax Business Phone System is a cloud-based VoIP service for distributed teams and businesses that need more than basic calling. It combines inbound and outbound HD calling with multi-level IVR, auto-attendant, ring groups, call queues, time-of-day and holiday routing, number support, SMS and MMS, voicemail transcription, call recording, and softphone apps. Mid-size teams can also connect SIP devices and deskphones, making the service a fit for organizations combining traditional phone hardware with browser, desktop, and mobile calling.
Pricing is paid and extension-based. The published monthly plans show Mid-Size Business at $19.99 per seat, Small Business at $21.99 per seat, and Starter at $24.99 per seat. Each listed plan includes unlimited local and long-distance calling and all listed features. Annual billing is offered at 20% off. A 14-day trial gives teams a defined period to review calling workflows before committing, while the per-seat model keeps costs tied to the number of extensions required.
Abbax’s strongest fit is for teams that want phone-system controls alongside business software. Integrations include Salesforce, HubSpot, Zendesk, Intercom, Gong, Slack, Microsoft Teams, Google Workspace, and Notion, with CRM integrations and screen pops supporting customer-facing workflows. The platform also includes an API, optional SSO, team messaging, video calls, and AI features. Choose it when routing depth, messaging, transcription, recording, and deskphone compatibility matter together. Teams seeking a free service or a simpler, flat-priced calling tool should look elsewhere.
