     +(91)-(44)-96217000
     +(91)-44-96217000

i try this expression is not working

    static bool IsPhone(string s)
    {
        return Regex.IsMatch(s, @"\(?\d{2}\)?[\s\-]?\d{3}\-?\d{10}");
    }

Well for one thing you're asking for a cluster of 3 digits when you expect 2 and a cluster of 10 when you expect 8 - I don't know what valid phone numbers are wherever you are but your examples won't match that.

I can also see a problem with your attempt to match the parens - with what you have both (91-44... and 91)-44... would be accepted. Regex OR | is your friend here I think.

Can't help you much more without knowing your locale, and if I were you and knew that I'd google for an appropriate phone regex - these things are non-trivial.
