title: CallKit error com.apple.CallKit.error.requesttransaction error 2
body: <p>I have tried many examples of starting an outgoing call on ios swift using CallKit.  I have enabled VOIP in capabilities.  In all cases it fails at:</p>
  
  <pre><code>callController.request(transaction) {
      error in
        if let error = error { print("Error requesting transaction: \(error)")}
  
   else { print("Requested transaction successfully")
              }
  </code></pre>
  
  <p>The error I get:</p>
  
  <pre><code>Error requesting transaction: Error Domain = com.apple.CallKit.error.request transaction Code=2 "(null)"
  </code></pre>
  
  <p>I can find no answer that matches Code=2.</p>
