ai-native-callcenter

rasonyang/ai-native-callcenter · ★ 283

An open-source, self-hosted AI call center: calls land on FreeSWITCH and are answered by a speech-to-speech voice model by default, with a flow deciding when to hand the caller to a real human agent in a queue. It ships as one Go binary with a REST+SSE API, OpenAPI spec, PostgreSQL and FreeSWITCH underneath.

Tel-Agent

Dpro-at/Tel-Agent · ★ 1.1K

Tel-Agent is an open-source, self-hosted gateway that connects a phone line to an AI agent: calls arrive over SIP, get checked against your routing rules, and are either passed to a human, blocked, or handled by an AI that can transfer calls, take messages, check a calendar, or call any HTTP endpoint. Every call is recorded, transcribed, and searchable.
