Refactoring validity check and prefix processing of dialed number
...
Command line help shows how many digits and what prefixes can be dialed.
Giving a station ID via command line will be checked for being valid.
The number to call the mobile statione will be checked for being valid.
Prefixes that are defined for a nework will be removed from station ID
automatically.
Multiple station ID lengths are supported:
* C-Netz: 7 or 8 digits, depending on area code length
* A-Netz: 5 or 7 digits; number is truncated to last 5 digits.
* IMTS/MTS: 5 or 7 digits, depending on phone's selector switch.
