# 21262: No AMD status callback URL provided

Log Type: APPLICATION

Log Level: WARNING

## Description

Answering Machine Detection was enabled on this call, but no AMD status callback URL was provided, so Twilio has no where to send the results when they are returned. AMD results will still be available in the /Calls resource once the call is complete.

### Possible causes

No AMD status callback URL was provided

### Possible solutions

Provide an AMD status callback URL when enabling Answering Machine Detection
