Call analytics, or phone call analytics, is the process of collecting and analyzing data from phone calls: where each call came from, who called and why, what was said, how long it took and what happened as a result. It applies to calls handled by people, AI voice agents or both.
In AI-powered systems, call analytics goes a step further. It can automatically classify intent, measure sentiment, detect issues, and surface coaching opportunities, without anyone reviewing calls by hand. Analyzing what is said inside each conversation, such as sentiment, topics and required phrases, is often called voice analytics.
For B2B companies handling high volumes of phone interactions, call analytics turns conversation data into operational intelligence.
Done well, using call analytics and post call analysis helps teams:
A SaaS company reviews 1,000 AI-handled support calls and sees a spike in calls categorized under “billing confusion.” Using this data, the team updates pricing page FAQs, refines agent scripts, and proactively emails customers, and those call types drop over the following weeks.
Call analytics is an essential growth tool. When tied into AI voice workflows, it enables faster iteration, more accurate targeting, and smarter automation strategies.
Every call on Retell AI produces a transcript, summary, sentiment, call outcome and any custom fields you define through post-call analysis, and the dashboard tracks call volume, duration, transfers and success rates. AI quality assurance scores calls against your own criteria.

Call tracking shows where a call came from, such as an ad or web page. Call analytics is broader: it also looks at what happened on the call and what it led to.
Common metrics include call volume, source, duration, wait time, abandonment rate, first call resolution, transfer rate, sentiment and outcome, such as a booking or sale.
Software that collects and reports this data. Call tracking tools such as CallRail and Invoca focus on marketing attribution, while contact center and AI voice platforms analyze the conversations themselves.
