a phone number to 20 digit ?
The limit to 20 digit for a phone number could be a potential risk since according to
IUT-T a phone number can have up to 15 digit + international prefix. Some country have
international dialing prefix greater than 6 digit.
Limit of 20 was chosen for several reasons:
- That is the maximum incoming party number size (24.008 Calling Party
BCD Number)
- Most networks do not support Calling Party BCD number more than 20
characters (24.008 Calling Party BCD Number)
- SMS Address is limited to 20 characters (23.040)
- oFono does not support EFadn extensions, and thus numbers are limited
to 20 characters (31.102)
There might be exceptions to this where more than 20 characters are
required. Patches are of course always welcome.
