To make domestic calls, dial 1+area_code+number or area_code+number. To make international calls, dial country_code+area_code+number.
As Wengo is a French company, all French numbers must be prefixed with 0 and other countries must be prefixed with 00.
Question to audience (or Martin), please explain:
If I move 2nd and 3rd plans to the end, user loses the ability to make international calls, with an immediate busy tone. They are not forwarded to the provider. Test button on "Dial Plan" setup page shows no problem even with this order. Why?
