Sign Up & Verify Your Business
Create your account in under 5 minutes. Verify your business information for caller ID legitimacy. We check your business is real to protect call quality and compliance.
Chat With Your AI Caller
Have a conversation with Phone Stack to train your AI. Describe your business, your pitch, your ideal customer, and how you want calls to go. No forms — just talk.
Upload Your Knowledge Base
Drag and drop PDFs, pitch decks, pricing sheets, and FAQs. Phone Stack extracts the information your AI needs to answer questions accurately on calls.
Pick a Voice
Preview and select from multiple natural-sounding voices. Each voice is optimized for sales conversations — professional, warm, and engaging. Adjust speed and tone to match your brand.
Import Your Contacts
Upload a CSV with your contact list. Map fields (name, phone, company, title), validate numbers, and tag contacts for segmentation. Phone Stack scrubs against DNC lists automatically.
Set Up Phone Numbers
Phone Stack auto-provisions local numbers matching your contacts' area codes. Numbers are warmed before use to build sender reputation and avoid spam flags.
Build a Campaign
Combine your AI profile, contact list, phone numbers, and schedule into a campaign. Set calling windows, timezone rules, and concurrency limits. Preview before launching.
Launch & Monitor
Hit launch and watch your AI make calls in real time. Monitor active calls with live transcripts, track answer rates, and see meetings get booked as they happen.
