Why it comes up: Aircall is a quoted sales dialer if you need a fuller conversation suite than Quo's Starter SMS line.
Stands out: Calls log back into HubSpot, Salesforce, Bullhorn, and Slack instead of living in a separate PBX.
Watch out: Plans start at three licenses, and no per-license price is published. AI Voice Agent minutes beyond the included bundle are consumption.
Best for
- Recruiting and SDR teams living in a CRM
- Agencies on Bullhorn that want a cloud handset
- Desks that need recording plus CRM logging

$29/user/mo 14 day free trial MCP API
Why it comes up: JustCall publishes from $29/user/mo for sales calling and SMS with a higher floor than Quo Starter.
Stands out: Calling, SMS and CRM logging on Team, a power dialer on Pro, AI coaching on Pro Plus, and a hosted MCP server.
Watch out: Two-user minimum, so Team starts at $58/mo. The AI Voice Agent is a separate per-minute add-on, and the power dialer starts on Pro.
Best for
- SMB sales and support teams that want calling plus SMS
- Desks already on HubSpot, Salesforce or Pipedrive
- Teams that want a power dialer on Pro

Why it comes up: KrispCall publishes from $12/user/mo annual if you want a cheaper seat and can skip Quo's Sona agent.
Stands out: Every plan includes one free US, UK, or CA number per user plus HubSpot, Salesforce, Zapier, Pipedrive, Intercom, Slack, Zoho, and monday.com among 100+ integrations.
Watch out: Starter is capped at 5 users. API and webhook access is listed as Coming Soon. The 14-day refund is a money-back window on the subscription, not a free trial, and usage add-ons are non-refundable.
Best for
- Solo agents and shops under 5 seats that want a US/UK/CA number for $12/user/mo
- Sales teams that need a power dialer and bulk SMS on Advance
- Support desks that want IVR, recording, and Slack or HubSpot in the same callbox

$30/user/mo Free tier Free trial
Why it comes up: Aloware publishes from $30/user/mo for power-dialer and SMS workflows aimed at sales floors.
Stands out: HubSpot/Salesforce-native calling and SMS with a 3-user package at $199/mo if you cannot hit the 10-seat Core floor.
Watch out: Core is $30/user (min 10). AloAi analytics is extra credits.
Best for
- HubSpot or Salesforce teams that call and text
- Speed-to-lead inbound
- US outbound that needs bulk SMS plus a dialer
