this field is used for those countries
there there is more than one possible masks
e.g. Brazil. In most cases this field is null
IMPORTANT! all masks MUST be placed in an ascending order
e.g. the shortest possible mask must be placed in a phoneMask
variable, the longer ones must be in altMasks list starting from
the shortest. That's because they are checked in a direct order
on a user input
this field is used to store real phone code
for most countries it will be the same as internalPhoneCode
but there are cases when system need another internal code
to tell apart similar phone code e.g. Russia and Kazakhstan
Kazakhstan has the same code as Russia +7 but internal code is 77
because most phones there start with 77 while in Russia it's 79
