Simple phone number formats like the one used for North America can be somewhat easily described with regular expressions, but Argentina's phone numbers are quite complex. For example, area codes can be 2-4 numbers long and can overlap. A prefix is used to denote mobile verse non-mobile numbers, and this prefix changes number and position when dialing internationally. The prefix must be used when calling internationally, but not when sending SMS internationally.
This means that Argentine phone numbers are best captured with a grammar, rather than regular expressions, so NT54 uses a finite state machine to process the number like a real hardware or software dialer.
If you're curious, you can debug the phone number processing like this:
