Suggestion: Can we forbid the number for the first step of number

[aozen]

For example: (+XX) YYY-ZZ-WW
This is the number format.
In my country country and most of the other countries phone codes end with "0".
+70 707 70 70 or +90 909 90 90
But when people calling each other without "+9"
0707 70 70 / 0909 90 90
So my customers cant figure out default country code section and writing one more 0.
writing "+90 090 09 09" instead of "+90 909 90 90".
I hope i could express myself. I can override your code but i can use your package all the time i sure :) And other people may need to this. We need to block 0 for 4. string.
+90 X.... This X can't be 0. Can we do this? Or should i just override?
