This guide is part of our series on AI call quality score.

A call quality score is a normalized numerical rating—typically evaluated from 0 to 100—that measures how effectively a sales representative or support agent conducted a phone conversation against company standards. Rather than relying on subjective gut feelings, Indian sales organizations implement automated AI call scoring to evaluate opening greetings, discovery questions, objection handling, and follow-up commitments across 100% of calls.

How a 0–100 Call Quality Index (CQI) Is Calculated

A comprehensive Call Quality Index breaks down customer phone conversations into five observable phases, awarding weighted points for specific conversational milestones:

1. Opening & Verification (15 pts): Did the rep clearly state their identity, company name, and reason for calling within the first 15 seconds?

2. Needs Discovery (25 pts): Did the rep ask open-ended questions and identify the prospect's commercial pain points?

3. Pitch & Solution Mapping (20 pts): Was the product benefit tied directly to the prospect's stated problem?

4. Objection Handling (25 pts): Did the rep address pricing, competitor, or timing pushbacks without becoming defensive?

5. Closing & Next Step (15 pts): Did the conversation end with a specific agreed date and time for follow-up?

Scaling Quality Audits Across Contact Centers

In high-volume BPOs and outbound call centers, manual sampling reviews only 2% to 3% of conversations. Automated platforms audit 100% of audio, enabling 100% call audit coverage that eliminates compliance blind spots.
