I never had to configure anything on the previous versions to properly call International numbers. I am not going to change all my phone numbers and put 00 in front since that does not work in every country! That would be a waste of time. My cell phone works with these numbers and the previous version of your software worked.
Also, who ever wrote the new version does not know how to write and configure the new software. It should work like the previous version and only if you want to play around to change setting then you can change it!
