It is requested preferably to route the first and second choice IDD call to India, based on the two digit area code, to VSNL gateway switches as given below: 

It is recommended to use the 2-digit Area Code analysis table for routing & screening out invalid Indian numbers dialed by your IDD callers. However, if technically this is prohibitive, 1-digit Area Code analysis is also given below for amendment of the switch database.
