# DialStack

> DialStack is embedded Phone System and VoiceAI for vertical SaaS platforms. Partners launch a fully branded phone system and voice agent for their own customers in days, on our carrier, compliance, and telephony engine. Built by telecom veterans who integrated voice into 100+ platforms serving 100,000+ small businesses.

DialStack runs the hard parts of a regulated voice offering (carrier networks, number porting, E911, STIR/SHAKEN, robocall mitigation, taxes and fees) beneath a clean REST API, TypeScript SDK, and a white-label admin portal. Voice lives inside the partner's product: calls arrive with matched customer context (Screen Pop), any number becomes a button (Click-to-Call), calls log themselves, and an included VoiceAI agent answers, schedules, and summarizes. Partners can also bring their own voice agent and connect it through the API.
