The server where I want to store asteriskcdrdb (MySQL): avts.com
The server where I want to store asterisk MySQL-database: emeaasterisk.com

Note: before I had all databases on avts.com. This morning I separated the two databases by mysqldumping "asterisk" from avts.com to "emeaasterisk.com". So, in emeaasterisk.com "asterisk" is the only database that exists (besides schema and that stuff of course).
