Web call from the dashboard Talk button connects but ends immediately with ‘Customer ended the call’ — no audio either direction. Assistant is set to ‘speaks first’ so it should greet on connect, but it’s silent then ends. Tested on both mobile Safari and desktop Chrome, mic permission is Allowed in Chrome, account has credits. Config: Deepgram transcriber, GPT-4.1, Elliot (Vapi) voice. Call ID 0557033e-1572-433a-8ba8-f54ef8ba4d857. What’s causing the instant disconnect?

Suggestion: Check your assistant configuration for conflicting server message settings. Specifically, make sure your assistant's config does not include

"phone-call-control"

in the

serverMessages

array, and that

phoneCallProviderBypassEnabled

is set to

false

. Here’s an example of the correct configuration:

json
{
  "phoneCallProviderBypassEnabled": false
}

After updating, retry the call to see if the disconnect issue is resolved.

Hey Khalaf, since you're hitting this on both desktop Chrome and mobile Safari the issue is likely network-side rather than device-specific. can you try reproducing on a mobile hotspot (completely different network)? that'll tell us quickly whether your current network is blocking the WebRTC audio path. also did this ever work before or has it always failed for this assistant?
