All external calls routes to Attendant instead of directly going to intended DDI number.I have checked the features,routing,public and internal numbering plan parameters with no solution(OmniPcx R10.x).Please help

Make trace - you will see CALLED number (length, type..).
Describe management - public/private/restricted numbering plan according CALLED number (especially if called number length more then 8 digits).
