                    //print(self.arrDict)

                    if (self.arrDict.count>0)

                cell1.vendorAdress.text=arrDict[indexPath.section] .valueForKey("address") as? String
                //cell1.externalView.hidden = true

                print("non premium user") 
                return cell1 
            } 
        }

Have a variable in premiumUsercell like as follows,

class premiumUsercell: UITableViewCell {
    var phoneNumber = ""
}

in cellForRowAtIndexPath add this code,

cell1.phoneNumber = arrDict[indexPath.section] .valueForKey("phone") as? String

in premiumUsercell, CallbuttonTap method

@IBAction func CallbuttonTap(sender: AnyObject) {

        var phoneString = "tel://\(phoneNumber)"
        let openURL = NSURL(string:phoneString)
        if openURL == nil {
            return
        }
        let application:UIApplication = UIApplication.sharedApplication()
        if (application.canOpenURL(openURL!)) {
            application.openURL(openURL!)
        }
    }

you can get the row number by getting the cell object from the button clicked. once you get the row number you can get the respective phone number from you json object.

UIApplication.sharedApplication().openURL(NSURL(string: @"tel:<your telephone number>"))
