I\'ve made an application is used to call predefined numbers upon button press. As far as i know the only way to make call inside app is to use \"tel\" or \"telprompt\". Whe
From your update, it suggests you're sending tel://... or teleprompt://... as a URL. The tel: scheme takes a series of digits. / is not a digit, so there's no reason you should be passing that as part of the number.
