OpenClaw v2026.5.16 Beta: xAI Grok OAuth Login, Multilingual Setup Wizard, Cron Run Controls

OpenClaw v2026.5.6+ added Telnyx real-time voice streaming, xAI Grok OAuth, and multilingual setup wizards. The infrastructure pieces are there, but deploying an OpenClaw agent as a production phone agent still requires stitching together voice plugin config, phone number provisioning, Telnyx/Twilio credentials, language routing, cron scheduling for outbound calls, and call analytics. This platform automates the entire stack. You point it at an existing OpenClaw instance, pick a phone number, set business hours and language preferences, and your agent is live on the phone network with its existing memory, tools, and skills intact. The AI voice agent market crossed $4.8B in 2026 at 38% CAGR, but existing platforms (Retell, Vapi, Aircall) are standalone and none connect to an existing OpenClaw agent runtime.
