Just wanted to add some more details to what Dovid mentioned. Many European countries do offer a non surcharge rate for US and Canada originated traffic. There are a few countries that put US/Canada in a different bucket where there is a surcharge, but its not the maximum. Then there are some countries where certain mobile carriers offer reduced rates but landlines and other mobile carriers don't. Some countries haven't implemented A number billing and just have a single rate no matter where the call originates from. Its a mess.
As for increasing your call completion problems, make sure you and your upstream are sending the call in full E164 format for your A number and B number. I've worked the past couple years to build a product that offers US/Canada originated traffic the non surcharge rate. Its hard to market due the complications of explaining it and then potential customers not being able to normalize their A Numbers appropriately. Unfortunately its not geared for self serve low volume customers that want to put in a credit card and go because of the fraud risks I'm not ready to assume. ~Jared On Fri, Jul 14, 2023 at 6:36 AM J.
