Hail.so has announced version 0.15 of an open-source system for phone, SMS, and email communication intended for both AI agents and human users. The project was submitted to Hacker News as a Show HN item. The listing currently shows a score of 1 and one comment. The supplied material does not establish its architecture, supported providers, deployment model, reliability, abuse controls, or security posture, so the release should be treated as an early project signal rather than validated infrastructure.
