) with specific query parameters to filter for calls that might have ended with errors? This endpoint allows you to retrieve multiple calls and might provide more filtering options than the "Get Call" endpoint.
Also, have you checked if the endedReason
field is available in the response from the "List Calls" endpoint? Sometimes different endpoints provide different sets of data fields.

Waited 300s But Transport Never Connected.
The log message Call waited 300s But Transport Never Connected
reveals the actual technical problem.
What's happening:
1. When Vapi initiates a call through Twilio, it waits for a transport connection to be established
2. In these cases, the system waited 300 seconds (5 minutes) for Twilio to connect the call
3. The transport connection never established, so the calls timed out
4. These calls ended with "unknown-error" status because the system couldn't determine exactly why Twilio failed to connect
This explains why you saw calls with "unknown-error" in the dashboard but they showed as "queued" in the API - they were stuck in an intermediate state where Twilio never properly connected the call.
This has been repeating for all of your calls.
You have to check with the Twilio team regarding these call failures, and if it's related to your Argentina phone numbers issue that you've mentioned.Ger贸nimo
