$25 is Starter on annual billing; Essential is $29 and Expert $49. Preview, power and parallel dialers, branded caller ID and AI conversation intelligence are add-ons, and CRM integrations do not turn on until Essential. Calling is still usage on top.
What we noted
Not the right fit for
Worth keeping in mind: Unlimited US and Canada calling with local numbers in 160-plus countries on a published seat price. HubSpot, Pipedrive, Salesforce, Close, and WhatsApp are named.

$15/user/mo Free trial API
Why it comes up: Voice plus SMS if you need texting with the dialer for recruiting.
Stands out: Dialer plus SMS with Bullhorn named next to HubSpot and Salesforce: agency recruiting actually shows up in the connector list.
Watch out: Engage is $15/user/mo; the $47 rung is the fuller sales/HR suite. Conversational AI, cadence, and CRM autofill are add-ons.
Best for
$9/user/mo Free trial MCP API
Why it comes up: CRM plus dialer if you do not want a standalone phone system.
Stands out: Calling inside the CRM (not a bolted-on dialer), plus WhatsApp, Calendly, HubSpot, and a first-party MCP.
Watch out: Phone lines are $1/line/month, which is not the CRM seat. Solo annual is $9/user. Calling is usage-based on top.
Best for
$30/user/mo Free tier Free trial
Why it comes up: US CRM-native calling and bulk SMS if CloudTalk's international story is unused.
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
$15/user/mo 7 day free trial
Why it comes up: Simpler shared calling if a call-centre SKU is overkill.
Stands out: Every plan includes one local or toll-free number per user, US and Canada calling and SMS, voicemail transcripts, the Quo API, and the Sona AI agent with 1,000 automation credits. ChatGPT and Claude MCP is listed on the cloud-VoIP feature page. Capterra (still filed as OpenPhone, titled Quo) is 4.2 from 64 reviews.
Watch out: Monthly Starter is $19, not $15. Business and Scale AI summaries, call analytics, and advanced CRM integrations start at $23/$35 per user per month annual. Extra numbers are $5/month. US texting needs 10DLC registration fees on top.
