Delay_answer when try import DIDs

Hi,
When i try to import DIDs, i get the following message:

Whoops\Exception\ErrorException
Undefined index: delay_answer
File:/var/www/html/admin/modules/core/Core.class.php:1968

  • Freepbx 13, asterisk 11.

Thanks.

You are missing some necessary columns in your csv file. First do an export of your DID file to get the necessary column headings.
