Outbound Sales Dialer

Overview

A B2B SaaS company had a 12-person sales team spending the majority of their day manually dialing prospects from a CRM list. Most calls went to voicemail, and reps were burning out from the repetitive grind. We built an AI-powered outbound dialing system that autonomously works through prospect lists, detects whether a human or voicemail answers, leaves personalized voicemails when appropriate, and only connects live prospects to human reps with full context displayed on screen. The system integrates directly with their CRM to log all activity and update lead scores in real-time.

The Challenge

The system needed to handle complex call routing logic, detect voicemail systems with high accuracy across hundreds of different carrier configurations, generate natural-sounding personalized messages, and integrate with a CRM that had rate-limited APIs. Compliance with TCPA regulations was also critical.

Our Approach

We built the dialer on Twilio's programmable voice platform with a custom AI layer. The voicemail detection uses audio analysis combined with timing heuristics for 97% accuracy. Each call script is dynamically generated by an LLM using prospect data from the CRM — company name, industry, pain points from previous interactions. When a live human answers, the AI conducts the first 30 seconds of qualification before warm-transferring to a rep with a screen pop showing all context.
