Grok Customer Support is a Grok bot template in the Personal category. Places the call by wiring a Twilio line through to Grok Voice, so the talking on your end is handled for you. You watch from the chat window and can redirect it while the conversation is still running. It stays on the line until the problem has genuinely been sorted out.
Capabilities
Works with Twilio — Twilio Skills and MCP provide procedural knowledge for AI coding agents — which APIs to use, in what order, and what to avoid. Covers Messaging, Voice, Verify, SendGrid, and 30+ products.
Memories
Profile — Grok Voice ↔ Twilio bridge hangup gate: hang up only after the errand success or a clear dead-end is confirmed; never mid-ID / mid-reference / on hold. The voice model may request hangup; the operator (or bot) must approve before the Twilio leg ends.
Log — Outbound voice stack: Node bridge that connects Twilio Media Streams (μ-law 8 kHz) to xAI Grok Voice realtime (wss://api.x.ai/v1/realtime?model=grok-voice-latest, audio/pcmu). Place calls with POST /call; expose PUBLIC_HOST over WSS (e.g. ngrok) so Twilio can reach /media-stream.
Log — Coach mode pattern: poll a live transcript (them vs agent), accept steer text from the operator in chat, POST /steer so Grok updates mid-call without announcing that it is being coached. Operator does not need to hear raw call audio.
Log — Enable Twilio dual-channel recording on every outbound bridge call so recordings can be pulled by call SID from Twilio Monitor → Logs → Recordings.
Log — Prefer a custom Grok Voice clone from the xAI console for outbound calls that should sound like the user. Grok Voice Agent Builder free numbers are mainly inbound; Google Voice is a poor fit for this bridge. Keep Twilio and xAI secrets in .env only — never in chat.
Log — Hold-music / IVR: raise VAD threshold and silence duration so hold music does not trigger endless agent speech; cancel in-flight responses while hold music is detected.
Log — Non-marketplace services this bot uses: xAI Grok Voice (realtime WebSocket API) and a self-hosted Node Twilio Media Streams bridge. Twilio marketplace plugin covers Twilio APIs; the bridge itself is local code, not an MCP server.
