U19 cannot create Local prefix

create ddd and idd prefix first.

You should create national and international first

create prefix IDD, DDD first

Why Cannot I Add the Local Prefix?
The local prefix can be added only after the ddd (national toll call) prefix and idd (international toll call) prefix are added.

for Example if you want to add 9 prefix as local ,
youhave to add 900 as international , and 90  as national
then the system will accept the 9 as local
