I am working on an iOS app and writing code to make calls from that app. It is working fine for non toll free numbers, But for some number such as 18601231000 for BigBasket, it is converting the number as +1(860)1231000 which when dialed comes as wrong number. But for numbers starting with 1800 it is working fine. I am searching solution of this query and taking help from some [ Register or Signin to view external links. ] and iphone blogs. If you have answer of my query please reply me. Please check my code snippet.
