Hi my fellow Agency owner If you're building AI voice agents — or trying to — this is for you.
Let me guess you've hit at least one of these on Vapi:
→ You built your agent, it worked perfectly in testing —
then after a platform update it started breaking randomly
and support took 2 days to reply (if at all)
→ Your Google Calendar tool says a slot is available and
books it — but the appointment was already taken
→ You're getting deepgram-transcriber-failed errors mid-call
and have no idea why it worked fine yesterday
→ Your knowledgebase file uploaded correctly, the agent
calls the tool — but returns "No document found" every time
→ You're posting in the Discord support channel and getting
no response while your client is waiting
Quick fix for the transcriber error — go to your assistant
settings and add a transcriber fallback plan. Set Deepgram
as primary and Gladia or AssemblyAI as backup. It won't stop
the root cause but it keeps calls alive while Vapi sorts
their end.
The full fix for all of these including the calendar
booking bug, knowledgebase issues, and how to actually get your agent stable in production — is inside
VoiceAgent Lab.
Inside when it goes live:
→ Step-by-step build guides for Vapi, Retell,
Voiceflow, ElevenLabs & Bland AI
→ How to stack platforms so you're never dependent
on one breaking
→ Real prompts and scripts you can deploy immediately
→ Pricing strategies and how to close clients
→ A community of builders who actually respond
Founding members get in at the lowest price it'll
ever be — locked in for life.
