The verdict
For a lean B2B team, Quo is the default pick. It starts at half the price, drops the three-user minimum that makes Aircall expensive before you've made a call, and its Sona AI agent actually answers the phone rather than just transcribing it. That's the right shape for a founder or a small team running shared numbers and texting without a legacy PBX.\n\nAircall earns its higher price in exactly one situation: a sales or support team putting real volume through a power dialer, wired into a deep CRM and helpdesk stack with strong analytics. If that's you, the 250+ integration catalogue and the auto dialer are worth the 30-USD-a-seat, three-seat floor. If it isn't, you're paying for a call-centre engine you won't run.
