You can record all of the messages for every one of those 10 languages. By default, the system installs English prompts. I have Spanish prompts recorded also. As I know, there is no source to download or get prompts already recorded.
I don’t have any experience with fax and Cisco, but I read about it, and seems to be possible.
I’m located in Quito, Ecuador, South America.
