Call search (edit)

If you or your agents receive an error message in the dialer, you can use Warehouse Calls to track what went wrong using SIP codes.

  1. Go to Warehouse in the menu on the left and choose Calls.

  2. Go to Columns in the Warehouse menu on the right and add the column SIP code. Every call has its own SIP code which is used for controlling communication sessions.
