    I have recently experienced this exact behavior. There doesn't need
    to be any active calls. It does seem related to the fact that an
    outbound call was previously made through google voice. A restart
    also resolves the issue for me as well.<br>
    <br>
    If there is already a JIRA ticket for this, can someone post the
    link? I can try and help by providing more testing details.<br>
