I have two Vapi phone numbers attached to assistants. Neither one is working today. I just get a call failed without it ever ringing. Is this a known issue?

Yes, there are several known issues that could be affecting your Vapi phone numbers 📱 Based on recent reports, users have experienced: - Outages affecting phone number functionality - Calls failing without ringing (similar to your issue) - Issues with voicemail detection - Calls dropping with HTTP 413 errors - Calls timing out unexpectedly Some troubleshooting steps you might try: 1. Check your network latency to ensure there are no significant delays 2. Review your configuration settings, particularly if you're using Google Voice or Twilio forwarding 3. Check your SIP URI formatting if you're using forwarding 4. Examine call logs from both Vapi and any connected services for specific error messages These issues might be related to either Vapi's system or Twilio's infrastructure, as there have been reports of interaction issues between the two services [source](
