No valid call flow at the current time 1. Account/plan suspended or credits exhausted 1. Routing to an empty queue or all agents unavailable 1. A policy block (blacklist, geo-restriction, caller-ID rule) Follow the checklist below and confirm success with a test call. ## When should I use this guide? Use these steps if callers report β€œit rings once, then hangs up” or your Call Logs show Rejected / No-flow events. --- ## πŸ“•Table of Contents 1.
