The implementation of ActiveCall _prettyPrintNumber does not use a proper international number formatter. Instead it seems to be hardcoded to assume that the number is USA format. This affects ActiveCall.toFormatted and ActiveCall.fromFormatted.
Steps to Reproduce
Try calling an international number like +52 55-2591-9530.
