Hi Denis,
Thanks for your answer.
Actually 24.008 states that the Called party BCD can have a maximum length of 43 octets,
we are far from the 20 characters supported by Ofono.
The Calling party BCD is not mandatory when making a mobile originated voice call
(24.008).
I hope this could help.
Regards,
Alain

Is there a particular motivation for Ofono to limit the max length of

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.
Regards,
-Denis
