is a letter like that enough sir? will they actually call whoever contact number provided in the reference letter?coz there's a rumor i read about that they will trace, call the person or they will even check or investigste or validate or whatever they call it if you really worked on that company.is this true?
They would be perfectly within their rights to do so. Part of VO's duty is to ensure all documents (including letters) they receive are real. A phone call is a good way of verifying experience that has been claimed. So they may or may not do it. It's at their discretion. What you read is not a rumour, it's a fact for many applicants.
