Best Virtual Phone System software

Virtual numbers from 100+ countries with local, mobile, and toll-free options make an international presence affordable

A free plan lets teams test the system before committing to paid tiers

Independent review data from G2, Capterra, and Trustpilot was unavailable at review time, so user sentiment is hard to verify

The listed pricing range tops out at $64,503/month, and combined per-seat plus usage-based billing makes total costs harder to forecast at scale

250+ native integrations—including Salesforce, HubSpot, Zendesk, Pipedrive, and Shopify—sync conversations and customer data automatically, so reps don't switch tabs or update records by hand

AI Assistants coach reps in real time during live calls with suggested responses, transcriptions, and sentiment, topic, and key-moment analysis, instead of only providing notes after the fact

Essentials and Professional require a three-license minimum and the Custom plan requires 25 licenses, so teams smaller than three users can't buy in at all

Usage-based AI costs stack up on top of seat prices: AI Voice Agents run from $0.19 per minute, AI Messaging Agents from $0.15 per conversation, and add-ons like AI Assist ($9), AI Assist Pro ($49), Analytics+ ($15), and WhatsApp ($10) are billed separately

Every plan includes unlimited minutes and a free professional greeting recorded by their voice talent studio, so a one-person business can sound polished without extra fees

The Team plan includes unlimited users at no extra charge, which avoids per-seat costs as a startup adds staff

Plan prices are not listed on the homepage, so buyers must dig into a separate compare-plans page to see what each tier actually costs

There is no integration marketplace highlighted — CRM and third-party tool connections aren't advertised, so teams dependent on those workflows should verify compatibility with support first
